Description

[0001] Sales system, method for operating a sales system, computer-implemented method, computer programs and data processing system

[0002] Field of invention

[0003] The invention relates to a sales system for goods and digital products, comprising at least one operating device, at least one storage device, and a dispensing device, as well as a method for operating a sales system. The invention further relates to a computer-implemented method, computer programs (sales platform, operator platform, monitoring and remote maintenance platform, and management platform), a data processing system, a computer-readable data carrier, and a data carrier signal.

[0004] The sales system described in the invention is also commonly referred to as a vending machine. The invention focuses on digitalization and automation. In particular, it incorporates technologies from the Internet of Things (IoT) for real-time monitoring, artificial intelligence (AI) for inventory and maintenance management, mobile and cloud-based control systems, and digital payment systems (NFC, QR code, cryptocurrencies).

[0005] State of the art

[0006] Sales and dispensing systems are known from the prior art, for example as vending machines, which, with a limited selection of often specialized products, are found in a variety of configurations as self-contained vending machines. Furthermore, dispensing systems, e.g., for dispensing packages, are also known. While functionally connected to a network, they are likewise specifically designed for a particular type of goods, such as packages, and implemented as discrete units.

[0007] These types of vending machines have been in use for decades and are based on mechanical or electromechanical systems for dispensing goods. These machines typically consist of the following components:

[0008] • Mechanical or electromechanical dispensing system: Products (hereinafter also referred to as goods) are dispensed via spiral trays, conveyor belts, or drop mechanisms. • Payment systems: Most traditional vending machines accept coins, banknotes, and in some cases, credit cards.

[0009] • User interface: Consisting of a numeric keypad or simple push buttons for product selection.

[0010] • Cooling and heating systems: Beverage vending machines often use cooling units or heating elements for hot drinks.

[0011] • Manual maintenance and inventory management: Operators must regularly check the inventory and manually refill the vending machines.

[0012] German patent application DE 101 49 619 A1 describes a method for controlling electronic parcel locker systems, primarily aimed at enabling flexible and centralized adjustment and management of operating parameters and access rights through server-based control commands. This method includes an interface that ensures the fast and efficient transmission of these commands. Furthermore, it allows for the dynamic adaptation of operating conditions and user interface properties, enabling individualized handling for different user groups. The transmission of control commands and data is carried out using standardized protocols such as XML over HTTP.

[0013] One disadvantage of this solution is the increased dependence on the constant availability and reliability of the central server. Furthermore, the central control system potentially represents an attractive target for cyberattacks, which jeopardizes the integrity and confidentiality of the controlled parcel locker systems.

[0014] From German patent application DE 197 19 525 C2, a person skilled in the art will recognize a method and a device for controlling a system with self-cash terminals, as already known from US patent application US 4 872 541. The core of the invention lies in the cyclical assignment of a payment processing unit to different self-cash terminals within defined time intervals. This eliminates the need for the operator to select a specific terminal in advance; instead, the payment amount is automatically assigned to the terminal currently connected to the payment processing unit. This approach simplifies the operation and use of the self-cash terminals.

[0015] A potential drawback of this solution could be that users might have to wait until their desired device is available, which could lead to inconvenience and potential customer dissatisfaction. Furthermore, the fixed order of device allocation could result in uneven usage during peak times, leading to inefficient device utilization.

[0016] The German patent application DE 197 28 885 02 describes a computer-controlled lending system that enables the provision of items for temporary use while ensuring security against unauthorized removal. The system comprises a central computer, communication terminals for interacting with users, and means for identifying items and users. Machine-readable identification devices attached to the items and users allow the lending process to be automated and monitored.

[0017] A potential disadvantage of this system could be the need for continuous technical monitoring and maintenance to ensure functionality. Furthermore, the system's complexity, particularly regarding the automated capture of identification tokens, could pose challenges to user acceptance. High initial investments in the technical equipment and potentially ongoing costs for software updates and system maintenance could also be limiting factors.

[0018] German patent application DE 689 13 352 T2 describes a vending machine characterized by electronic programmability. The machine allows for the flexible allocation of storage space to specific products based on their sales rates. Using coded inputs, the machine can be programmed to provide more or less storage space for certain products. This optimizes storage space management according to the varying sales dynamics of the products.

[0019] Potential disadvantages of this system include the complexity of the programming and the need for constant updates of sales data for efficient storage allocation. Furthermore, the reliance on electronic control and programming could increase the susceptibility to errors, especially in the event of system failures, which could compromise operational reliability.

[0020] German patent application DE 692 16 399 T2 describes a system of vending or service machines consisting of several components connected via a bus system. These components can communicate independently with each other and respond flexibly to commands transmitted via the bus system in a general command mode or a direct access mode. This enables direct information exchange between the components without a central master component, thereby avoiding delays and increasing system flexibility.

[0021] A disadvantage of the system is the complexity of the bus communication architecture, which requires precise management of signal timings and exact configuration of delay times to prevent collisions and communication errors. Furthermore, the possibility that any component can initiate communication leads to unpredictable bus traffic, making system diagnostics and troubleshooting more difficult.

[0022] German patent application DE 10 2014 015 216 B4 describes a control system for vending machines or service dispensers, comprising a programmable logic controller (PLC) and a module. The module has an input and output for external protocols, enabling communication with the PLC. A key component of the module is a communication processor capable of converting signals between the external protocol and the PLC protocol. This configuration allows various sensors and actuators using external protocols to be connected to a standardized PLC, thus increasing integration and flexibility across diverse applications.

[0023] However, a disadvantage of this solution is the complexity and potential cost of the assembly, especially if it needs to support different protocols. Furthermore, the reliance on a specialized communication processor requiring specific firmware could limit the system's maintainability and scalability.

[0024] Documents EP 1 089 243 A2 and US 6 401 010 B1 describe a communication system for an automatic vending machine that includes a main control unit and several subordinate control units connected via synchronous signal lines. The coin and banknote recognition control units communicate with the main control unit at a rate of 4800 bps, while the customer service and sales control unit communicates at a rate of 19200 bps. These separate signal lines prevent communication errors that could occur if different communication rates were used in a common control section. A potential disadvantage of this system is that the separate signal paths and different rates could increase system complexity and make it difficult to integrate new control units or scale the system.Furthermore, the need to constantly monitor and adjust synchronization and communication speeds could entail additional technical effort. Additionally, the requirement for separate signal paths could lead to higher installation costs and potential sources of network interference.

[0025] Publication EP 1 335 562 A2 presents a vending machine management system that enables efficient communication between a host computer and multiple vending machines across different networks and communication protocols. A key component of the system is a protocol converter installed between the host computer and a second communication device. This converter adapts the local communication protocol of the second device to that of the first, and vice versa. This allows the network to be established using the second device without requiring any modifications to the host computer.

[0026] A potential drawback of this solution could be the added complexity of using a protocol converter, which could introduce potential sources of error into the system and make maintenance more difficult. Furthermore, performance bottlenecks could occur if the converter cannot adequately handle the data rate or the efficiency of data transmission between the different networks and protocols.

[0027] Publication WO 2015 / 051097 A1 presents a new model for vending machines that reduces the increasing complexity and costs of traditional machines by utilizing widely available mobile computing devices as mobile application platforms. This model shifts all business intelligence from the machines to a centralized computing unit (e.g., cloud-based) and a community of mobile devices used by consumers at the point of sale. This system allows the vending machines to communicate with the mobile devices via a proximity-based wireless interface, with transactions and authentication handled by the central unit and the mobile devices. However, this approach also has its drawbacks.Although the infrastructure costs for the machines themselves can be reduced, the reliance on a continuous, stable internet connection and the requirement for each user to have a compatible mobile device could limit the system's accessibility and reliability in certain environments. Furthermore, the centralization of data processing necessitates extensive security measures to protect consumer data, which again increases system complexity in other ways.

[0028] A traditional vending machine has a coin slot, a banknote slot, a debit card reader, a PIN pad for entering the item's compartment number, a PIN pad for entering the PIN, and a change compartment. The familiar vending machine is a self-contained unit and essentially has its own rudimentary client built in, which, based on the entered compartment number, tells the machine which item should be dispensed. The applications of such a solution are very limited. Furthermore, the more advanced systems described in the various publications also have several disadvantages. Specifically, there are a number of challenges and limitations, in particular: a) High maintenance costs

[0029] • Vending machines must be inspected regularly to ensure they are functioning properly.

[0030] • Problems such as blocked goods dispensing or faulty payment systems often require manual intervention.

[0031] • Malfunctions are usually only discovered through customer complaints, leading to lost sales. b) Inefficient inventory management

[0032] • Operators must either manually check inventory or rely on approximate sales statistics.

[0033] • Often, goods are restocked either too early or too late, which can lead to lost sales or spoilage. c) Limited payment methods • Many older vending machines only accept cash or basic card payments.

[0034] • Digital payments via smartphone, NFC or cryptocurrencies are often not integrated.

[0035] • A lack of change can prevent customers from making purchases. d) Lack of personalization or customer loyalty

[0036] • Traditional vending machines do not offer the possibility to analyze purchasing behavior or make individual offers.

[0037] • Customers have no way to benefit through loyalty programs or digital discount promotions. e) Lack of remote monitoring and diagnostics

[0038] • Operators have no way of monitoring the status of the machines in real time.

[0039] • Repairs are often only carried out when breakdowns occur, resulting in long downtimes.

[0040] • Troubleshooting often has to be done on-site, as remote diagnostics or software updates are not possible. f) High energy consumption

[0041] • Cooling and heating systems often run continuously, without adapting to external conditions or user frequency.

[0042] • There are no automated energy-saving modes that adjust consumption.

[0043] While there has been some progress in the digitalization of vending machines in recent years, with the integration of various technologies to address some of the aforementioned problems, these systems still exhibit significant weaknesses. For example, some manufacturers offer systems that send sales data to a central cloud to improve inventory management. However, these systems often only provide basic reports and do not allow for automated analysis or reordering. Touchscreens and digital user interfaces are already in use for a more engaging user experience. Many of these systems, however, require regular software updates, which are not always automatic. Some newer vending machines use camera and sensor integration to recognize users via facial recognition or RFID for improved interaction and personalized offers.However, data privacy concerns and high costs prevent the widespread adoption of this technology.

[0044] Although there are initial attempts to digitize vending machines, existing systems are often inadequate, expensive, or not scalable. A fully integrated digital system combining IoT, AI, and modern payment technologies is not yet known.

[0045] Object of the invention

[0046] The object of the invention is therefore to offer a sales system that is flexible, suitable, and adaptable for selling a wide variety of goods with their specific requirements, and which also helps to avoid the disadvantages of the prior art. The aim is to create a fully networked, intelligent sales system. This sales system is intended to optimize the entire sales process, from product selection and payment to inventory management, maintenance, and energy efficiency. Furthermore, the invention aims to provide a method for operating a sales system, a computer-implemented method, computer programs (sales platform, operator platform, monitoring and remote maintenance platform, and management platform), a data processing system, a computer-readable data carrier, and a data carrier signal.

[0047] Description

[0048] The problem is solved by a sales system for goods and digital products, comprising at least one operating device, at least one storage device, and one dispensing device. According to the invention, the sales system comprises a master system and at least one client system.

[0049] A client system consists solely of electrical, electronic, and mechanical components and possesses no inherent "intelligence," meaning it has no control or input devices. Furthermore, together with its associated storage system, it serves as a "warehouse" for the dispensed items. Without the master system, the client system is incapable of complex processes. The sales system according to the invention is a complete system that allows simple dispensing machines, the client systems, and the master system to be networked together. The entire system is controlled via the central master system. It is also advantageous that the complete system can control and operate additional peripheral devices.

[0050] The master system also includes a payment unit, which can be used to purchase and dispense digital products. The master system can operate completely without cash. A cashless payment terminal handles this. A receipt printer is integrated into the master system for dispensing digital products.

[0051] Another aspect is the ability to offer products subject to a minimum age requirement. For this purpose, a reader unit has been installed that verifies age using a debit card or digital ID card. The central control unit for the master system is the central, hardware-controlled computer unit through which the entire system is operated.

[0052] In the preferred embodiment, the key component is a 32-inch display. This display is covered with a glass pane, the glass having the following properties:

[0053] • chemically tempered, safety glass,

[0054] • Anti-reflective coating AG80±10 on one side,

[0055] • Opaque organic printing RAL9005,

[0056] • LIV / IR protective coating on one side,

[0057] • Thickness of 3 mm,

[0058] • Ground edge 0.3 ±0.1 x 45° ±1°.

[0059] The panel and the touch / glass unit are bonded together using optical bonding to generate a clearer and sharper image. The monitor is fixed in the machine by six customer-specific mounting points, designed as M4 threaded bolts.

[0060] The preferred touch firmware used to operate the touch input device has the following settings: one-finger functionality, water detection for outdoor use, wired interfaces, and palm rejection for improved usability. This allows for a wide range of applications, both indoors and outdoors.

[0061] The sales system according to the invention offers numerous advantages. The overall system comprises a wide variety of technology strands, which are ultimately integrated into a unified system. The sales system according to the invention is not merely a product dispensing system, but rather an integral component in many applications across numerous vertical markets. The sales system according to the invention offers the possibility of offering, advertising, and purchasing both physical and digital products. The application that controls the sales system according to the invention accompanies the consumer live throughout their entire shopping journey.

[0062] A vertical target market is gas stations, which will increasingly develop towards being "staffless" over the next few years. For this to happen, it is necessary to serve not only the additional products from the sales system according to the invention, but also the infrastructure located at the station.

[0063] The master system comprises the operating unit, which in turn has a user interface physically connected to the master system. This user interface is preferably designed as a touchscreen and displays the current user interface. The master system and the client system are connected by a signal link through which control signals are transmitted between the master system and the client system. This allows each of the client systems to be controlled by the master system, at least in its essential and system-wide functions.

[0064] As an alternative to the local operating device, a data connection to another terminal device is provided, such as a smartphone or computer, whose screen displays the user interface, whereby the connection is suitable for data transmission to the master system.

[0065] In an advantageous embodiment, the master system comprises the dispensing unit, and a client system comprises at least one storage unit designed for storing and dispensing goods from a product compartment. The master system and the client system, which is structurally directly connected to the master system, are linked by a goods transfer system for transferring the goods from the at least one storage unit to the dispensing unit of the master system.

[0066] Existing vending machine shops typically contain several individual vending machines. The goods must be removed individually from each machine because the dispensing mechanism consists of a separate dispensing flap on each individual dispensing cabinet. Against this background, it has proven advantageous to have a centralized dispensing system for goods that are available for sale in the master system and in at least one client system. The at least one client system preferably connects directly to the master system. The present invention thus represents not only a cross-network cloud solution but also offers the possibility of centrally dispensing goods from multiple dispensing devices from a single dispensing compartment.According to a preferred embodiment, the master system includes an integrated storage device for goods that cannot be openly displayed, since the master system does not have a viewing window. This applies in particular to tobacco products, for which open display is not permitted. Thus, according to a preferred embodiment, the master system includes a tobacco vending machine and also serves as a dispensing device.

[0067] The goods transfer system, by which the goods are transferred from the at least one storage unit to the dispensing unit for central distribution, is provided and installed in and between the master system and the client system. The goods transfer system comprises transport means, preferably conveyor technology, particularly preferably designed as conveyor belts, and transports the goods from the at least one client system to the master system. For this purpose, a transfer opening, preferably located in the side walls of both the master system and the client system, is provided. The transport means are individually height-adjustable, with the outer transport means or conveyor belt, which receives the goods ejected from the designated product compartment in the client system, being positioned higher than the inner transport means or conveyor belt, which receives the goods from the outer conveyor belt. The inner transport means or conveyor belt is located within the master system.

[0068] Further advantages arise if the master system includes a monitoring device that records the dispensing process and, in particular, the total volume and / or weight of the goods entering the central goods chute of the dispensing device. This is done to prevent the goods chute from overfilling, where the total volume of goods exceeds the capacity of the central goods chute of the dispensing device.

[0069] The monitoring device signals that the dispensing process pauses before the capacity is exceeded, and the operating unit prompts the user to remove the goods from the chute. This is indicated, for example, on the operating unit's display, where a message appears stating that the dispensing unit should be emptied. After the goods have been removed, the user can confirm that the dispensing process should continue. The same procedure applies if fragile goods are placed in the chute; these must be removed to prevent damage before further goods are added.

[0070] The monitoring device enables the secure dispensing of multiple fragile items in a single transaction. In contrast, conventional vending machines only allow the dispensing of one fragile or delicate item at a time, as damage or breakage could occur if several such items were to fall on top of each other during dispensing. Currently, purchasing two fragile items requires two separate transactions and two separate payment processes.

[0071] The invention is designed with digital control such that the system stores information about which goods are marked as fragile. This allows any number of fragile items to be purchased in a single transaction, as the dispensing process pauses after each fragile item is dispensed and only resumes once the customer has removed the item. To ensure double security, the system detects this through integrated sensors and also requires customer confirmation that the product has been removed. This confirmation is provided via the digital user interface.

[0072] In an advantageous embodiment, the master system and the at least one client system each have at least one temperature zone, for example, a refrigerated or deep-freeze zone, which corresponds to the required storage conditions of the goods. Such a specially temperature-controlled refrigerated or deep-freeze zone is added separately, particularly in a further client system. The temperature within the temperature zone is continuously adjustable. In particular, the deep-freeze zone is set up in a client system specifically designed for this purpose.

[0073] In an advantageous embodiment, a mobile ring scanner is provided for use by an operator. The ring scanner is used, according to a first method, to scan the goods to be placed in the storage system. The application then displays the corresponding storage location to the operator on a display device, e.g., a tablet PC, and the goods are placed in the specified compartment. The number of items placed is then entered into the application.

[0074] According to an alternative embodiment, the ring scanner is used to scan the storage compartment of the storage device for identification by a second method, wherein the application on the display device outputs the corresponding product, the goods are placed in the compartment and the number of goods placed in the compartment is entered into the application.

[0075] The ring scanner is worn comfortably by the operator like a ring on their finger and can read and transmit a code. In addition to general overviews of stock levels, sales, system status, and more, this application also offers the integrated capability to quickly and efficiently manage what is arguably the most complex process – restocking. For this purpose, the employee performing the restocking also uses the ring scanner.

[0076] The master system and at least one client system are equipped with sensors and other measuring devices for recording at least the internal temperature, external temperature, operating times, user times, error messages, and other data. The data recorded by the sensors and other measuring devices is stored in a database, particularly as evidence for inspections, especially for inspections related to the secure cold chain, and for addressing customer complaints regarding defective goods delivery.

[0077] The invention also leads to an optimization of energy consumption. Conventional vending machines often operate with fixed cooling or heating mechanisms, regardless of usage patterns. This results in unnecessarily high energy consumption. The invention offers a solution through energy-adaptive control via sensors and AI.

[0078] • Reduced lighting during low usage

[0079] • Dynamic cooling control based on temperature, sales and restocking data

[0080] • Automatic energy-saving modes outside of peak hours

[0081] For sustainable energy management, the cooling and heating systems adjust their output to usage times and outside temperatures. A standby mode outside of peak usage times further reduces power consumption. Additionally, a combination of intelligent display management and motion detectors saves further energy.

[0082] According to an advantageous embodiment, the master system's control unit is therefore equipped with an energy-adaptive control system, which is intended to provide light and cooling as needed. In this context, it has proven advantageous to prevent cold air leakage from a temperature zone in the storage unit of the master system and the at least one client system by arranging a cold airlock at least in the transfer openings of the master system and / or the at least one client system. This cold airlock opens during operation of the goods transfer system and closes again after the goods transfer is complete. Opening and closing are preferably achieved by damper panels. The temperature zone is an area with a controlled temperature for goods that must be stored at this temperature. Limiting the temperature control to this zone results in energy savings.

[0083] A preferred embodiment of the sales system provides that, in a two-part interior of the master system, a tobacco vending machine is arranged on a first side in the upper area for dispensing tobacco products to the dispensing device located in the lower area. On a second side of the master system, a control box is arranged, which includes electronic and electrical components for controlling the master system and, connected via the signal link, the at least one client system.

[0084] The front door allows the operator easy access to certain areas. Preferably, the master system's interior is divided into two sections, with a tobacco vending machine installed on one side to dispense tobacco products. This eliminates the need to house tobacco products in client systems, as they cannot be openly displayed in unmanned sales systems. It has also proven advantageous to have a control box on the other side of the master system, providing easy access to all electronic and electrical components for monitoring and maintenance. Rear access is then typically unnecessary. This design allows for less restrictive installation options, such as wall mounting.

[0085] Another advantageous embodiment of the sales system features a hardware-controlled computer unit running the Linux operating system as the central control unit for the master system, through which the entire system is operated and controlled. Advantageously, the client system includes sensors and other measuring devices, enabling the recording, reading, and transmission of indoor and outdoor temperatures, operating times, service times, error messages, and other data.

[0086] It has proven advantageous to use computer programs for controlling the sales system. A first computer program, a management platform, is intended for the system-wide control of at least one sales system, but especially of several sales systems. The management platform encompasses the control of the entire system, which includes multiple sales system locations; a specific system location, which can include several sales systems; the individual sales system at that location; the individual master system; the individual client system; and even a single product compartment in the storage facility. Functional changes, in particular temperature settings, compartment changes, product changes, and much more, can be made via the management platform through remote maintenance.Furthermore, at least one inventory, product data, price information, master data, interfaces, locations, expiration dates, users and displayed content are managed by the computer program management platform.

[0087] The computer program management platform enables dynamic pricing based on real-time data. This solves an existing problem: vending machines currently display static prices, regardless of demand or stock levels. This leads to suboptimal pricing, especially for perishable goods. The invention offers a solution by optimizing prices using AI, based on the following factors:

[0088] • Time of day (e.g., higher prices during peak hours, discounts during off-peak hours)

[0089] • Inventory levels (e.g., price reductions for products nearing their expiration date)

[0090] • Weather and demand analyses (e.g., price adjustments for cold drinks on hot days)

[0091] The computer program management platform also enables automated inventory control and intelligent restocking planning. While conventional vending machines require regular manual inventory checks, and shortages or expired goods lead to lost sales or food waste, this invention avoids these problems.

[0092] In this invention, IoT sensors capture the current inventory in real time. A preferably cloud-based platform analyzes sales data and calculates demand forecasts. Automatic orders are sent to suppliers or operators as soon as the inventory falls below a defined limit.

[0093] According to a preferred embodiment of the management platform computer program, it includes an integrated warning and notification system that removes products from a refrigerated storage facility from sale by displaying them as no longer available and issuing a corresponding system message to an operator when the minimum temperature has risen by a predefined range for a predefined period. This occurs when a maximum temperature specified for the goods is exceeded and the duration of the exceedance exceeds a predefined time limit.

[0094] A particularly advantageous embodiment of the computer program management platform provides at least one interface to one or more peripheral devices, selected from the following: hot beverage vending machine, car wash, car vacuum cleaner, car tire inflator, hotel services, and digital products, enabling fully automatic integration of additional services, in particular the dispensing of hot beverages, the use of a car wash, a car vacuum cleaner, and / or a system for checking and topping up tire pressure. Furthermore, hotel services and digital products are included, whereby the customer or...When a user selects an additional service on the system, they receive a voucher with the corresponding QR code. A QR code reader is installed in the accompanying hot beverage vending machine, car wash, car vacuum, and tire inflation machine, which scans the QR code and dispenses or executes the additional service. Alternatively, the QR code can be displayed digitally on the customer's device and shown on their screen, or printed on paper using a receipt printer.

[0095] This will be explained in more detail using the specific example of "hot drinks," a seamless integration of hot drink dispensers. The product selection is already displayed on the digital user interface. After paying for the hot drink, the customer receives a voucher in the form of a QR code. This simply needs to be held up to the hot drink dispenser, and the drink will be prepared. The technology is interconnected (cloud-based) in such a way that each QR code can only be redeemed once. Furthermore, according to the preferred design, this QR code can only be redeemed at the hot drink dispenser located within the sales outlet. The goal here, too, is to give the customer the opportunity to select a wide variety of goods in a single transaction and only have to pay once.

[0096] The invention also enables the integration of third-party peripherals, which is particularly necessary at certain locations of the sales systems. This involves the integration of existing or newly added machines and systems. For gas stations, electric vehicle charging stations, and rest stops, the integration of existing car washes has been implemented. Customers can again select all kinds of goods in a single shopping process and also obtain a coupon for, for example, a car wash. The coupon—either electronically as a QR code or on paper—can then be redeemed at the adjacent car wash. The technology is based on networking (especially via a cloud), so each code can only be redeemed once. It can also be configured that this code can only be used at the car wash located at the point of sale.

[0097] The invention also enables the integration of digital products. In addition to offering physical goods (such as beverages, food, drugstore items, and everyday necessities), the system also integrates the offering, sale, and distribution of digital products. Besides QR codes for hot drinks and coupons for car washes, the invention also offers vouchers, gift cards, and top-up functionalities for prepaid cards, such as mobile phone credit. For this purpose, the sales system according to the invention is directly connected to providers of these products via a cloud. The selection of the various vouchers and cards is made via the touchscreen, and the respective product is added to the shopping cart.

[0098] Certain cards require age verification, which is carried out immediately before the payment process. After successful age verification, the selected product is synchronized with the provider's server in real time, and the corresponding voucher code is generated via the cloud.

[0099] After successful payment, the respective voucher code is issued, preferably via the printer built into the master terminal. Redeeming the code in a store or online resynchronizes all relevant data with the provider's server and subsequently invalidates the voucher after the amount has been credited.

[0100] Furthermore, the invention provides for the integration of intelligent advertising. Within its backend, the invention features a content management platform that allows personalized advertising content in the form of images or videos to be stored across systems and locations. This CMS also allows for the storage of fixed scripts with precise sequences and defined durations. In addition to displaying content on traditional screens, which translates to a 32" screen per system, an additional option has been created to display this content in large formats. This is achieved through digital display of the glass surfaces, which preferably each have a screen size of 55". Content can also be played across multiple media, thus further expanding the overall display area.

[0101] The system reacts to motion sensors on the display, and as soon as it is touched or someone approaches, the display stops and the product portfolio is revealed through the glass pane, which was previously opaque.

[0102] According to another embodiment, a computer program sales platform is included, wherein at least the following menu items can be selected on the operating device controlled by the computer program sales platform: language selection, selection between direct purchase or collection of reserved shopping baskets, product selection, quantity selection, shopping cart, ordering a carrier bag, age verification, payment and goods issue.

[0103] The introduction of flexible and secure payment methods is planned, whereas many traditional vending machines only support cash or simple card payments. However, customers increasingly expect contactless or mobile payment options. The invention offers a solution by integrating various payment methods. These include NFC payments (Apple Pay, Google Pay), QR code-based payments (e.g., WeChat Pay, PayPal), cryptocurrency payments (e.g., Bitcoin, Ethereum), and in-app purchases with customer accounts or subscription models.

[0104] Furthermore, it has proven advantageous to include a computer program operator platform that controls at least the maintenance and restocking of goods, with the transfer of data on the goods and / or the goods compartment from a scanner, preferably a handheld scanner. Additional advantages result from the use or availability of a computer program monitoring and remote maintenance platform that monitors multiple locations and the individual systems at a location for errors, temperatures, and operating times, and logs the collected data. Moreover, changes to temperatures, compartments, and products can be made via various remote access points, preferably with different levels of expertise, into which the respective user is assigned.

[0105] Improved remote maintenance and fault diagnosis solves long-standing problems: with conventional vending machines, malfunctions are only detected when customers report a problem. Repairs often require on-site intervention, leading to extended downtime. This invention offers a solution through real-time monitoring of machine systems (e.g., temperature, mechanics, payment systems) using IoT sensors. Furthermore, automatic fault diagnosis is performed, and early warning systems notify the operator via app or cloud dashboard. This enables remote troubleshooting and software updates without physical access.

[0106] For optimized maintenance and fault detection, sensors and a cloud connection record the machine status in real time. System errors and other malfunctions are automatically detected and reported to the operator via a known communication channel, such as a push notification to a smartphone or an email to a maintenance center. A distinction is made between faults that can be resolved remotely (e.g., program flow disruptions by restarting the system) and other faults (e.g., mechanical defects) that require on-site service by a technician. This reduces maintenance costs because only a portion of malfunctions necessitate a costly on-site visit.

[0107] Effective maintenance is essential to ensure the reliable operation of the sales system and individual vending machines. This is where predictive maintenance comes into play, made possible by modern technologies, particularly networking and data analysis. Predictive maintenance is a method that uses data from various sources to monitor the condition of machines and equipment and detect potential failures early on. Unlike reactive maintenance, which only intervenes after a failure, and preventive maintenance, which is performed at fixed intervals, predictive maintenance is based on real-time data and forecasting models.

[0108] Within the scope of the present invention, predictive maintenance is implemented in various ways:

[0109] • Sensors and IoT: The sales system according to the invention is equipped with sensors that continuously collect data on temperature, fill level, noise, power consumption and other parameters. This data is sent via the Internet (IoT system) to central systems and analyzed by the management platform computer program.

[0110] • Data analysis and machine learning: Analyzing the collected data allows for the identification of patterns and trends that may indicate potential problems. Machine learning algorithms, preferably implemented in the computer program management platform, can predict when certain components might fail and recommend appropriate maintenance measures.

[0111] The data analysis for predictive maintenance of components of the sales system according to the invention comprises several steps:

[0112] • Data acquisition: Sensors in the components continuously collect data on various parameters such as temperature, fill level, power consumption and operating times.

[0113] • Data transmission: This data is sent in real time via the Internet of Things (IoT) to central servers or cloud platforms.

[0114] • Data preparation: The collected raw data is cleaned and brought into a uniform format to make it usable for analysis.

[0115] • Data analysis: Using algorithms and machine learning models, data is analyzed to identify patterns and anomalies. Various techniques are employed: o Descriptive analysis: This technique describes what happened in the past and helps to identify historical patterns. o Diagnostic analysis: It investigates the causes of problems and anomalies. o Predictive analysis: This technique uses historical data and machine learning to predict future events, such as when a component is likely to fail. o Prescriptive analysis: It provides specific recommendations for action based on the predictions of the predictive analysis.

[0116] • Visualization: The results of the analysis are visualized in easy-to-understand dashboards and reports, enabling maintenance teams to react quickly and effectively.

[0117] • Automated notifications: When potential problems are detected, notifications are automatically sent to the responsible maintenance teams, who can then take appropriate action.

[0118] This process enables operators of sales systems according to the invention to ensure that the sales systems always function optimally and that downtime is minimized. If the analysis identifies a potential problem, notifications are automatically sent to maintenance teams. They can then intervene before a failure occurs.

[0119] The sales system is modular and can be adapted for various applications, thus enabling scalability and future expansions:

[0120] 1. Food and beverage vending machines:

[0121] • Automatic cooling control for fresh products

[0122] • Dynamic price control for perishable goods

[0123] 2. Electronic items and accessories:

[0124] • Vending machines for power banks, headphones or smartphone accessories

[0125] • Smart goods dispensing with RFID or facial recognition technology

[0126] 3. Medical products and pharmacy vending machines:

[0127] • Automated dispensing of over-the-counter medications with digital age verification

[0128] • AI-powered suggestions for related products

[0129] 4. Parcel stations and logistics solutions:

[0130] • Integration with online shops for Click & Collect systems

[0131] • Blockchain-based tracking systems for transparent supply chains. The problem is further solved by a method for operating a sales system for goods and digital products, comprising at least one operating device, at least one storage device, and one dispensing device, as described above or according to one of claims 1 to 23. According to the invention, the following steps are provided for a sales transaction, which are executed or skipped by a computer program sales platform: a. User identification, which can be skipped; b. Language selection on the operating device or another terminal device; c. Selection between direct purchase and collection of reserved shopping carts, wherein in the case of the reserved shopping cart, at least steps d) and e) are skipped; d.Determining the price for the current sales transaction, taking into account boundary conditions selected from at least the following data sources to determine the change: weather, ambient temperature, time of day, sales, quantity and remaining shelf life of the goods, and user identification. e. Selection of goods and products, quantity selection, and verification of the shopping cart, whereby step f) can be skipped. f. Ordering a carrier bag, which can be skipped. g. Age verification during goods and product selection, where required and if step a) has been skipped. h. Selection of the payment method. i. Payment at the payment terminal or via the other terminal device. j. Issuance of digital products and vouchers, whereby the output is as a printout in the receipt printer (34), on the operating device, or on the other terminal device. k.Ejection of goods from the product compartment of the storage facility in at least one client system, and transport to the central goods chute of the dispensing facility in the master system. l. Verification of correct goods dispensing and provision of the goods in the goods chute. m. Checking the total volume of goods and for fragile goods in the goods chute and stopping provision if the central goods chute is at risk of being overfilled or after a fragile item has been provided. n. Resumption of provision after goods have been removed.

[0132] Following a beneficial further development of the process, the price indication for the current sales transaction is determined in the computer program management platform, thereby resulting in an automatic change of price indications for offered goods, whereby boundary conditions are incorporated to determine the change, which are selected from at least the following data sources: weather, ambient temperature, time of day, sales, remaining shelf life of the goods and user recognition, and whereby a learning system optimizes the changes and incorporates the boundary conditions as training data.

[0133] User recognition enables a personalized user experience and customer loyalty. While conventional vending machines offer no way to address customers individually or make them personalized offers, this invention eliminates this shortcoming. This is achieved through:

[0134] • Integration of a mobile app or a digital user interface with personalized recommendations:

[0135] • Customers receive suggestions based on purchase history

[0136] • Loyalty programs with discounts or free products

[0137] • Gamification approaches such as point systems or exclusive offers

[0138] The process described above in steps a) to n) constitutes a computer-implemented method and is executed as such by a computer. Furthermore, the invention encompasses a data processing system comprising means for executing a computer-implemented method comprising the described steps. Likewise, the invention encompasses a computer program comprising instructions that, when executed by a computer, cause it to execute the method according to the described steps. Further computer programs have already been described above. Finally, the invention also encompasses a computer-readable data carrier comprising instructions that, when executed by a computer, cause it to execute the method according to the described steps, and a data carrier signal that transmits the computer program.

[0186] By using modern technologies and intelligent data analysis for predictive maintenance, operators can significantly increase the efficiency and reliability of their sales systems. This leads not only to savings in effort and costs, but also to a better customer experience and a longer lifespan for the sales systems and their components.

[0187] The significant advantages of the sales system according to the invention compared to conventional vending machines, the combination of IoT, AI and modern payment systems, are summarized in tabular form below and compared to the respective technical problem and the solution provided by the invention.

[0188] Notwithstanding the individual sub-problems that are addressed, the unified problem of the invention as a whole is as explained above.

[0189] Examples of implementation

[0190] The invention is explained in more detail below with reference to the description of exemplary embodiments and their illustration in the accompanying drawings. The drawings show:

[0197] Fig. 7: schematically a block diagram of a sales system of the multiple system type according to the invention; and

[0198] Fig. 8: schematically a block diagram of a sales system according to the invention of the type conveyor dispensing system.

[0199] Fig. 1 schematically shows a perspective view of an embodiment of a sales system 1 according to the invention. This system comprises a master system 20 and four client systems 40, which are controlled in their essential functions by the master system 20, but the client systems 40 also have their own control devices, in particular for the mechanical components. The master system 20 has on its front, which is formed by the front door 21, an operating device 22, which here is designed as a touch input device 22, and a user terminal 30 (see Fig. 3). The touch input device 22 displays all necessary information and is touch-sensitive, so that operating areas can also be displayed interactively and dynamically and selected accordingly by finger pressure.

[0200] Furthermore, the master system 20 includes a dispensing unit 26, which is designed as a concealed opening easily accessible to customers. The selected goods, supplied from the client systems 40, are collected in the dispensing unit 26 and made available for removal. The goods are supplied by means of a goods transfer system 52, 54 (see Fig. 2).

[0201] Each of the client systems 40 has an internal storage unit 42 into which the offered goods can be placed and automatically retrieved by means of appropriate control. A viewing window 43 on the front of each client system 40 provides a view into the storage unit 42 and of the goods offered therein, thus supporting the customer's visual selection and information in addition to the display of the goods on the touch input device 22. The side walls 44 of the client system 40 as well as of the master system 20 have transfer openings 46 (see Fig. 2).

[0202] The entire vending system 1 is equivalent to a single conventional vending machine, but offers great flexibility regarding the quality and quantity of the products offered. This means that a single machine can provide several different temperature zones. Various systems are possible, and the configuration is not limited to these specifications:

[0203] • System S: 2 temperature zones, sufficient for 118 different goods,

[0204] • System M: 3 temperature zones, sufficient for 180 different goods,

[0205] • System L: 5 temperature zones, sufficient for 328 different goods.

[0206] Each temperature within its own zone on the respective Client System 40 is continuously adjustable from +2°C to +18°C. A separate deep-freeze zone in another Client System 40 is also available (-22°C). Furthermore, an unlimited number of digital products can be integrated into each system. The number of vending machines connected in series is unlimited, as the Master System 20 is not restricted in this respect.

[0207] A standard refrigerated display case features a cooling unit with a continuously adjustable temperature between +2°C and +18°C. Additionally, the system includes a dispensing system that can be set to temperatures as low as -25.8°C in the freezer compartment. Therefore, each system offers numerous temperature settings within a total range of -25.8°C to +18.0°C.

[0208] To comply with general regulations and laws regarding the cold chain and frozen food chain regulations, the temperature data of each system is checked and digitally logged every 5 seconds. According to these regulations, goods that have been outside the prescribed refrigerated or frozen temperature range for a certain period of time may no longer be sold. These regulations are integrated into the overall system. Should a technical malfunction cause the temperature to exceed a predefined value, the system detects this and immediately removes the goods from the digital assortment, making them unavailable for purchase.

[0209] The sales system's architecture is modular and consists of several intelligently networked components. This architecture combines IoT sensors, cloud computing, AI-supported data analysis, modern payment technologies, and an adaptive user interface to ensure smooth, automated, and efficient operation of the sales machine.

[0210] The system architecture can be divided into five main areas:

[0211] 1. Hardware subsystem (physical components and sensors)

[0212] 2. Software subsystem (control, AI and cloud platform)

[0213] 3. Communication infrastructure (networking of components)

[0214] 4. Security mechanisms (data, transaction and operational security)

[0215] 5. Scalability and modularity (expandability of the system)

[0216] The hardware subsystem comprises the physical components of the vending machine as well as the embedded sensors and actuators for controlling product dispensing, payment processing, and environmental sensing. The overall system consists of two key mechanical core components: the master system and the client system. Each master system can operate and control any number of client systems. Conventional master-client systems can only control a maximum of four clients. The master system contains the digital control unit and serves as the command center for all connected client systems. The client systems are used for product storage, product cooling, and product dispensing. According to the invention, three standard sizes of the vending system are provided, with either one master and one client system operating together, or alternatively, two or four client systems.

[0217] The storage system is equipped with a dispensing mechanism for each product compartment, which can be implemented as a spiral mechanism, a conveyor system, or a sliding mechanism. The dispensing of physical products is digitally controlled and can therefore be carried out using spiral technology, miniature conveyor belts, or sliding technology.

[0218] In the conveyor system (also known as belt technology), a motor-driven conveyor belt moves, carrying the goods to be dispensed. This conveyor module is equipped with microswitches that signal to the master system as soon as a product leaves the belt. The pusher mechanism consists of a screw spindle which, when rotated, moves the rear pusher forward, thus conveying the product towards the dispensing point. In spiral technology, the goods are stored in the spaces between a wire spiral, so that the products are ejected when the wire spiral rotates. A variety of different spiral sizes (diameter, length, pitch, and resulting number of goods) are available for product storage and dispensing.

[0219] For safe and reliable operation, automatic detection of successful product dispensing is essential. The sales system according to the invention therefore has electronic and optical sensors throughout the entire goods transport and dispensing area. The dispensing of physical goods goes through many individual steps, directed by the control unit of the master system, each of which is checked for success or failure in parallel. The master system can thus automatically repeat any step that has been identified as unsuccessful. The entire system therefore has automated self-monitoring control of each individual step. A failed or missed dispensing is therefore impossible, except in cases of human error during stocking or incorrect entry of initial stock levels.

[0220] Storage and temperature systems also ensure safe and reliable operation, in particular intelligent cooling / heating modules with adaptive control and sensors for monitoring temperature, humidity and product shelf life.

[0221] Access systems for maintenance and refilling include electronically secured compartments with RFID or QR code access and automatic door opening for authorized service personnel.

[0222] For safe and reliable operation, IoT sensors will continue to be used for environmental and status monitoring. These preferably include:

[0223] • Inventory sensors (weight sensors to detect the fill level of each product line and optical sensors to detect removed products)

[0224] • Environmental sensors (temperature and humidity sensors for fresh products, brightness sensors for adjusting the display and interior lighting)

[0225] • Fault sensors (vibration and noise analysis for detecting mechanical problems, voltage sensors for monitoring the power supply)

[0226] • User interaction sensors (proximity sensors to activate the display when a customer approaches, optional facial recognition or RFID for personalized user experience)

[0227] In a preferred embodiment, the payment module, as part of the master system, is implemented as a multi-payment system and features an NFC terminal for contactless credit cards, Apple Pay, and Google Pay, a QR code scanner for wallet payments (PayPal, WeChat Pay, crypto wallets), and (optionally) fingerprint or facial recognition for registered customers. Security mechanisms for payments are particularly preferred, especially end-to-end encryption of transaction data and PCI-DSS-compliant payment interfaces. The software subsystem is of paramount importance to the sales system according to the invention; it is the core component and consists of a combination of embedded control programs (firmware of the master and client systems), a cloud platform for data processing, and AI algorithms for optimizing sales processes.Specifically, the software subsystem includes firmware and embedded software, cloud backend and data platform, user interface or mobile app, and communication infrastructure.

[0228] In this context, firmware and embedded software (edge ​​computing) take over the real-time control of the mechanical components, the control of the product output at high speed, the self-calibration of the sensors to reduce errors, the local preprocessing of sensor data (edge ​​AI), the detection of faulty product outputs, and immediate fault diagnosis without cloud connectivity.

[0229] The cloud backend and data platform handle IoT data management, including the storage of sales, inventory, and maintenance data, and real-time synchronization with all vending machines in the network. Furthermore, it offers AI-supported inventory analysis and restocking planning, including automatic demand forecasts based on sales trends, weather data, holidays, and other factors, as well as a smart logistics interface for managing supply chains. The cloud backend and data platform also utilize machine learning for price optimization. This includes adjusting prices based on demand, time of day, weather, and inventory levels, as well as dynamic discount campaigns, for example, for products nearing their expiration date.

[0230] The user interface and mobile app, according to the preferred design, offer a) a touchscreen interface for interactive product presentation with 3D views and content information, designed for multilingual operation and barrier-free control. For users of the mobile app, additional features include the storage of personal purchase history and recommendations, digital loyalty points and special offers, as well as remote pre-ordering of goods and products with a reservation option, for later retrieval and collection at the master system. The communication infrastructure is also essential, serving to network the components and ensuring reliable and fast communication between them, which is crucial for the smooth operation of the machine.The preferred communication protocols are: MQTT (Message Queuing Telemetry Transport) for real-time transmission of sensor data, REST API & WebSocket for communication between the cloud backend, mobile apps, and the machine, and Bluetooth & NFC for direct interaction with mobile devices. A network connection offers a flexible and straightforward setup option without geographical limitations: 4G / 5G or Wi-Fi module for cloud connectivity, including a fallback solution using local edge computing processes if no internet connection is available.

[0231] Since the digital vending machine processes sensitive data, comprehensive IT security measures are integrated, particularly regarding data, transaction, and operational security: end-to-end encryption for all cloud communications, anonymization of user data for compliance with local data protection laws, and multi-factor authentication for operator access.

[0232] Hardware tamper protection: Sabotage and theft protection through motion sensors and GPS tracking, automatic locking mechanisms in case of unauthorized access, and real-time alerts to operators in case of tampering attempts.

[0233] Scalability and modularity: The architecture of the digital vending machine is designed so that it can be easily expanded or adapted to new business models.

[0234] Modular design: Flexible configuration for different product types (food, electronics, pharmaceuticals), easy remote software updates via OTA (over-the-air) mechanism, expandability through additional sensors and modules (e.g., biometric identification)

[0235] Integration with external systems such as API interfaces for ERP and CRM systems, compatibility with online marketplaces for omnichannel commerce, and linking with delivery robots or drones for autonomous restocking: The invention offers a modern architecture that fully digitizes and automates vending machines as components of the sales system. The combination of IoT sensors, AI-supported optimization, flexible payment systems, and a secure cloud infrastructure makes the machine a future-proof, efficient, and customer-friendly sales system.

[0236] Fig. 2 schematically shows a detail, the transfer device 52, 54, of an embodiment of a sales system 1 according to the invention. The transfer device is necessary because the sales system 1 has a single dispensing hatch, which is centrally located in the master system. Thus, the master system is the central unit for the ordering process, the payment process, age verification, dispensing of digital products, and ultimately also dispensing of all physical goods.

[0237] For this purpose, the goods must be moved from the respective dispensing units 26 to the central master system 20. The challenge here is to maintain the respective refrigerated temperatures at which the goods are stored and not to unnecessarily increase them during the dispensing process. Furthermore, an "overflow" of the dispensing chute at the central system must be prevented.

[0238] The side wall 24 of the master system 20 and the side wall 44 of the client system 40 each have a transfer opening 46, which is closed by bulkhead dampers 48 to prevent unwanted outflow of the cooled air. The bulkhead dampers 48 are activated and opened at the time of goods transfer and closed after the goods transfer is complete. The timing of the damper opening and closing is controlled by the control unit in the master system 20.

[0239] After completion of the payment process and at the start of the goods issue, both bulkhead flaps 48 are automatically opened, the conveyor belt 52 is moved by the control system through the transfer opening 46 into the adjacent master system 20 and at the same time the conveyor unit starts transporting the goods to the dispensing device 26.

[0240] Both conveyor belt 52, used for transferring goods from the storage facilities, and conveyor belt 54, which receives the goods in the master system 20 and prepares them for dispensing in the dispensing chute, are offset in height to ensure a smooth transfer from one conveyor belt 52 to the other conveyor belt 54. As a result, the goods always fall downwards by the height of the offset during transport, thus preventing jams or jamming. In the diagram, the arrow direction indicates the direction of movement of the upper section of the conveyor belt, on which the goods rest during transport.

[0241] In this way, the transfer of goods is carried out both from one client system 40 to another, and from the client system 40 adjacent to the master system 20 to the master system 20. The transport of goods is stopped when the capacity of the output device 26 is reached. Only after the goods held there have been removed and corresponding confirmation is the transport of the remaining goods continued.

[0242] Two integrated functionalities prevent the output tray in the master system from overflowing when multiple items are purchased:

[0243] • Storage of goods and packaging dimensions in the backend of the merchandise management system and simultaneous algorithmic start of an analysis to calculate the space requirement.

[0244] • Integrated sensors and light barriers that continuously monitor the fill level in the master system.

[0245] If the system detects an impending overflow, the dispensing process is interrupted and the customer is notified of the necessary removal of goods, in particular by a display on the control unit 22 in the master system 20. During this removal of goods from the goods chute, which is accessible after opening the front flap, a protective barrier mechanically prevents the customer's hand from coming near moving parts.

[0246] After the first items have been removed, the customer confirms this on the digital display of the operating unit 22. The system then uses sensors and a light barrier to verify the accuracy of the entry. If this is confirmed, the dispensing process continues. Once all items have been dispensed and removed, the customer is notified that the dispensing process is complete. The conveyor belt 52 returns to the dispensing unit, the client system 40, and the bulkhead flaps 48 between the master system 20 and the client systems 40 are closed, and the sales system 1 is ready for the next customer. Fig. 3 schematically shows a detail of the user terminal 30, an embodiment of a sales system 1 according to the invention. The user terminal 30 includes the payment terminal 38 on the left side, which is suitable for all types of payment.It includes, for example, a card reader, a corresponding PIN pad and an NFC reading device, which allows both cards (e.g. credit cards, debit cards) and smartphones to be read contactlessly for the payment process.

[0247] Optionally, a unit that allows payment with bills and coins, including change, can also be included. However, this is not desirable in many cases, but could still be provided in other situations, e.g., in a hotel where there is no security risk and customer comfort is to be increased.

[0248] The right side of the user terminal features an ID card reader 32 (required, for example, for the purchase of tobacco products and alcoholic beverages with age restrictions), a receipt printer (for printing receipts as well as issuing vouchers, tokens, and similar products). For entering and using such vouchers and tokens, the user terminal 30 includes a payment terminal 38 and a QR code reader 36.

[0249] Fig. 4 shows a flowchart of the four computer programs that control the sales system 1: the management platform, the sales platform, the monitoring and remote control platform, and the operator platform. The flowchart also represents a computer-implemented method. Furthermore, the invention includes a data processing system comprising means for executing a computer-implemented method comprising the steps described below. Likewise, the invention includes a computer program comprising instructions that, when executed by a computer, cause it to execute the method according to the steps described below. Finally, the invention also includes a computer-readable data carrier comprising instructions that, when executed by a computer, cause it to execute the method according to the steps described below, and a data carrier signal that transmits the computer program.The management process via the computer program management platform encompasses the administration of users and customers, the locations of master systems (including associated client systems), and the master data of these systems. Furthermore, it manages merchandise and product data, as well as the associated price information, which is then transferred to the sales platform (see description below), also taking flexible pricing into account.

[0250] For automated inventory management, the following are required:

[0251] • Sales data is continuously analyzed to optimally plan refills.

[0252] • AI algorithms predict the demand for goods based on

[0253] Sales trends and seasonal trends.

[0254] • Operators can centrally control the filling process and thus reduce unnecessary journeys.

[0255] The sales process, digitally controlled by the computer program sales platform, unfolds as follows:

[0256] • Customer arrival: The customer approaches the sales system and sees a digital user interface, the control unit 22, which displays the available products and their prices, but initially offers a language selection as well as the option "Pick-up or product selection". The customer authenticates themselves via app, NFC, or biometric recognition.

[0257] • Product selection: The customer selects the desired product by tapping the corresponding icon on the touchscreen or digital display. The user interface can also display additional information such as nutritional information or special offers. Product selection is made via touchscreen or app. A shopping cart is displayed, and age verification is performed if required due to the selected items.

[0258] • Payment process: o Digital payment: The customer has the option to pay using various digital payment methods, e.g., credit card, debit card, mobile payment systems such as Apple Pay or Google Wallet, or even contactless payment via NFC. o Payment processing: The payment via digital payment methods is processed. Once the payment is confirmed, the machine processes the transaction. For digital payments, a secure connection is established with the payment service providers to authorize the payment.

[0259] • Product release: After successful payment, the selected product is automatically released. The machine activates the necessary mechanisms to transport the product from the storage area to the dispensing compartment. After the product is automatically dispensed, sensors detect the removal. The product dispensing process is shown and described in detail in Fig. 5.

[0260] • Notification: The digital user interface displays a message indicating that the product is ready for collection. An audible signal may also sound to alert the customer.

[0261] • Product removal: The customer opens the dispensing tray and removes the product. The user interface can also display a thank-you message to the customer and invite them to make another purchase or provide feedback.

[0262] • This completes the purchase process for the customer. The following additional processes also take place internally within the system.

[0263] • Data recording: The machine records the transaction, including product selection, payment details, and time. This data is sent in real time to central servers or cloud platforms to monitor inventory and plan future maintenance or restocking needs.

[0264] • Maintenance and inventory management: The collected data is analyzed to monitor product stock levels and schedule restocks in a timely manner. Maintenance teams are notified as needed to ensure the vending machine is always operational. This process makes the sales process at a digitally controlled vending machine efficient and user-friendly, increasing both customer satisfaction and operational efficiency.

[0265] The computer program monitoring and remote control platform allows, after selecting a station or sales system, an error query to obtain information about current or (possibly automatically) resolved malfunctions.

[0266] Furthermore, individual sensors can be queried, for example, to obtain information about temperatures in specific storage facilities. This data is logged, allowing for historical analysis and documentation. In addition, remote maintenance, such as a restart, or remote control of the sales system becomes possible.

[0267] The computer program "Operating Platform" is used when loading the sales system with goods. It helps the operator assign goods to the correct storage unit and the corresponding product compartment. Preferably, a scanner is used that either scans the product compartment identifier and then displays the corresponding item on the operator's device or on the screen of the master or client system. An alternative embodiment provides for scanning the product itself to then display the corresponding product compartment.

[0268] Preferably, a ring scanner is used for scanning, which the operator wears on their hand.

[0269] Fig. 5 schematically shows a flowchart of a goods issue process within the sales platform of a sales system according to the invention, following confirmation of the shopping cart, age verification, and completion of the payment process. The process described below corresponds to the steps "Issue Check" and "Ejection / Check" that belong to the "Sales Platform," as shown in Fig. 4.

[0270] The process begins in the upper left corner with the calculation of goods dispensing by a control unit of the master system 20. The goods to be dispensed are assigned by the sales system 1, or its control unit, to the individual dispensing systems and sorted accordingly. This applies particularly to the number of goods to be taken from each system cabinet or dispensing system. The master system 20 and the client systems 40 are referred to as system cabinets when physical goods are stored in the associated storage unit 42 for dispensing via the dispensing unit 26. The calculations specifically check whether the selection includes fragile goods. Furthermore, a calculation is performed based on the physical dimensions and weights stored in the sales system or the control unit. From this information, the dispensing sequence is determined in the next step.The focus is on ensuring that heavy goods are handed out first to prevent them from falling on and damaging other goods. Fragile goods are handed out last to prevent any other goods from falling on them, which could also damage the fragile items.

[0271] Once these calculations are complete, the actual goods issue begins (see box, middle right). The items in the shopping basket are retrieved from storage unit 42, which is configured here as product compartments, in the calculated sequence, for example, by lift. The lift delivers the relevant items to the goods transfer system, conveyor belt 52, specifically to conveyor belt 54. The maximum number of items that can fit on conveyor belt 54 has already been calculated in advance.

[0272] In the next step, the bulkhead flaps 48 of the transfer openings 46 are opened in both the master system 20 and the client system 40. This allows the conveyor belt 52 from the client system to be inserted into the transfer opening 46 of the master system 20, so that the transfer from the conveyor belt 52 of the client system 40 to the conveyor belt 54 of the master system 20 can take place.

[0273] Meanwhile, the control unit of the master system 20 continuously monitors for any potential overflow of the conveyor system, in particular the conveyor belts 52 of the client system 40 and the conveyor belt 54 of the master system 20, as well as the dispensing unit 26 in the master system 20. This prevents malfunctions that would lead to a blockage of the goods dispensing and thus of the entire sales system 1.

[0274] Furthermore, the system checks whether the maximum permissible number of goods or the maximum permissible total weight of all goods in the dispensing unit 26 has been reached. If either of these criteria—an overflow or a maximum value for number or weight—is reached, the goods transport is stopped. To do this, the conveyor system is stopped, conveyor belts 52 and 54 come to a halt, and at least conveyor belt 52 is retracted into the client system 40. The transfer openings 46 are then closed to maintain a stable climate inside the respective system cabinets, particularly the temperature. If an excessive temperature increase is detected, rapid cooling is initiated after the complete dispensing process to prevent the permissible temperature range from being exceeded or remaining below it for an unacceptable period.

[0275] At the same time, the customer is prompted to remove the goods already dispensed from the dispensing unit 26. The sales system 1 verifies the removal via a light barrier and weight; the customer is also prompted to manually confirm the removal. If the removal is successful, the dispensing process continues until all goods have been dispensed or a maximum number or weight of goods is reached, requiring another dispensing. Once the last item has been removed, the customer is prompted to confirm, and this is simultaneously verified by a light barrier. When the dispensing process is completely finished, the conveyor belt 52 is retracted into the client system 40, and the bulkhead flaps 48 of the transfer openings 46 in the side walls 24, 44 are closed.

[0276] Fig. 6 shows a system architecture of a sales system 1 according to the invention, in particular the linking of the central multi-tenant system as a superior control and management instance, which is linked to and can influence a plurality of sales systems 1. The administrator has access to the central multi-tenant system, through which the sales systems 1 (hereinafter referred to as System 1, System 2, etc.) of various customers (Customer 1, Customer 2, etc.) can be accessed, with each customer operating one or more sales systems 1. The administrator can access, control, and monitor the sales systems 1. This enables the management of hosting, data storage, monitoring, and the system itself, as well as security, user management, statistics, and system logic. The system logic includes the management of login, reservation, checkout, and other functions.

[0277] For each customer, both the administrator and the customer themselves can influence the branding and corporate identity, edit the product range and prices, and set up an ERP interface (a connection that enables data exchange between an Enterprise Resource Planning (ERP) system and other software applications, such as CRM systems, e-commerce platforms, or logistics software) and payment providers. The most important terms from this presentation are defined and explained below. In sales, the term "bundle" refers to a strategy in which several products or services are combined into a package and offered at a discounted price. The goal is to increase the overall value for the customer while simultaneously boosting revenue. An example of a bundle would be an electronics store offering a laptop together with a mouse, a bag, and software at an attractive package price.This method can motivate customers to buy more, as they feel they are getting a good deal.

[0278] White label customers are customers who sell another company's products or services under their own brand name. This means the manufacturer or service provider (white label provider) produces or offers something. The white label customer (often a retailer, reseller, or platform operator) buys this product or service and resells it – under their own brand (branding) and often with their own design.

[0279] An ERP system or ERP application is software that helps companies integrate and manage their business processes. It includes modules for various areas such as finance, human resources, production, warehousing, and sales. The goal is to increase efficiency and create a central data source that enables better decision-making.

[0280] A CRM system is an integral part of this. A CRM application is software that helps companies manage their customer relationships. It offers functions for capturing, storing, and analyzing customer data, automating sales processes, and conducting marketing campaigns. The goal is to improve customer interactions and increase efficiency in customer management.

[0281] Branding refers to the process of creating and maintaining a brand. It encompasses everything that constitutes a brand, including its name, logo, design, language, and how it communicates with the outside world. The goal is to create a unique identity that stands out from others and leaves a lasting impression on target audiences. Corporate identity (CI) is a part of branding and refers to a company's visual and communicative appearance. It includes elements such as the logo, colors, fonts, and the design of business stationery, websites, and other communication materials. CI ensures that the company is perceived as consistent and professional.

[0282] The checkout process in a purchase is the process by which a customer pays for their selected products and completes the purchase. This can take place both in a physical store and online. At checkout on the sales system according to the invention, the goods are placed in the shopping cart, payment is made, and the transaction is completed.

[0283] A login is the process by which a user signs up to a system, website, or application to gain access. This is usually done by entering a username and password. The login serves to verify the user's identity and ensure that only authorized individuals have access to specific information or functions.

[0284] A WebSocket is a communication protocol that enables a bidirectional, persistent connection between a client (e.g., a web browser) and a server. This connection remains open, allowing both sides to send and receive data at any time without needing to establish a new connection. WebSockets are commonly used for applications requiring real-time communication, such as chat applications, online games, or live data feeds.

[0285] In IT, a fallback solution is a backup plan or alternative method that is activated when the primary system or main solution fails or becomes unavailable. The goal is to ensure business continuity and minimize downtime. Fallback solutions can take various forms, such as redundant servers, alternative networks, or manual processes.

[0286] Payment service providers are companies that offer solutions for processing payments at vending machines. These providers enable the acceptance of various payment methods, such as credit cards, mobile payments, or contactless payments. They ensure that transactions are processed securely and efficiently. Cross-selling is a sales technique in which a customer is offered additional products or services that complement what they have already purchased or intend to purchase. The goal is to increase revenue and maximize customer value by selling related or complementary products. An example would be if a customer buys a smartphone and is also offered a matching protective case or headphones.

[0287] The customer system, referred to as "Customer 1" in the diagram, can be used to control both a webshop and brick-and-mortar retail systems (e.g., "System 1"). Items selected in the webshop can then be reserved and picked up at a specific location within brick-and-mortar retail system 1. Within brick-and-mortar retail system 1, inventory management, product range, pricing, bundles of different goods, and cross-selling can be controlled.

[0288] Fig. 7 schematically shows a block diagram of a sales system 1 of the multi-system type according to the invention, in which the sales system operates with distributed goods dispensing. The goods are dispensed separately in each of the client systems. This simplifies the technical equipment because the goods do not have to be gathered and transported for a central dispensing point, a task handled by the hardware control system, among others. Each client system also has a control unit, implemented here as a Raspberry Pi computer.

[0289] The master unit includes all higher-level functional modules, including a mini-PC for central control, an operating unit designed as a touch interface, an EC terminal for payment functions, a receipt printer for issuing vouchers, a QR scanner for scanning QR codes, and another scanner.

[0290] Fig. 8 schematically shows a block diagram of a sales system 1 according to the invention, of the conveyor dispensing system type with unified goods dispensing in the master system. In addition to the components that the conveyor dispensing system described in Fig. 7 also has, a conveyor system 1 and a hardware controller are also present. The hardware controller of the master system controls the equipment required for the central dispensing of goods from the client systems, i.e., the transport equipment, in particular the conveyor belts 52, 54, and the bulkhead flaps 48, which open the transfer openings 46 in the master system 20 and in the client system 40 for goods dispensing and then close them again. This is shown in Figures 1 and 2.
