[0031] Reference will now be made in detail to the exemplary embodiments, as illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to any one preferred embodiment. On the contrary, the invention is intended to cover alternatives, modifications, and equivalents, which may be included within the spirit and scope of the embodiments as defined by the appended claims.

[0032] Vending machines are typically used to dispense products to consumers in an on-demand manner in a variety of locations, such as grocery stores, convenience stores, shopping centers, sports or concert venues, gas stations, offices, and movie theaters, among others. Vending machines may be used to dispense any of a wide variety of products, such as food and beverages, or merchandise, such as toys or electronics. While vending machines may provide consumers with a convenient way to purchase products, existing vending machines have several drawbacks.

[0033] Vending machines generally do not allow consumers to physically select a specific product to purchase. Instead, consumers simply pre-select the type of product to purchase via an interface, and the vending machine dispenses the selected type of product. As a result, consumers cannot physically pick up and inspect the product before purchasing it. This may be undesirable if the consumer is unfamiliar with the product and would benefit from the ability to inspect the product, its packaging, nutritional information, and ingredients. Furthermore, consumers may prefer to personally select the product to purchase to ensure the product is not damaged and to ensure they are purchasing the desired product.

[0034] Existing vending machines often require consumers to enter a code corresponding to a desired product. Taking the time to determine a product code and enter the product code adds a step to the process of purchasing a product and introduces the possibility of user error. A consumer may accidentally enter the wrong product code, resulting in the dispense of an incorrect product. Similarly, because a consumer cannot physically select and remove a product from the vending machine, there is a risk that the vending machine will be unable to dispense the selected product, or that the dispensed product may be damaged, expired, or otherwise defective. Once dispensed, a consumer cannot return the incorrect or defective product.

[0035] Furthermore, vending machines are generally configured to dispense a single product at a time. If a consumer wishes to purchase multiple products, the consumer must repeat the steps of entering payment, identifying the product code, and entering the product code to have the products dispensed. This can be time-consuming and inconvenient, and consumers may prefer to purchase multiple products in a single transaction.

[0036] Some embodiments described herein relate to a product vending system having a product storage cabinet and a handle including a digital display, a control unit, and a payment processing unit, where upon receiving payment or pre-authorization at the payment processing unit, the control unit unlocks the cabinet door and allows a consumer to physically select one or more products for purchase. In this manner, the consumer can pick up and inspect the products to be purchased, ensuring that the correct products are selected and dispensed to the consumer. Furthermore, when a consumer accesses a storage compartment, the consumer can easily select and purchase multiple products in a single transaction. Some embodiments described herein relate to a handle with a digital display, a control unit, and a payment processing unit that can be retrofitted to an existing cabinet to convert the cabinet into a product vending system. As a result, a product vending system can be formed by integrating the handle with the cabinet, allowing the operator of the product vending system to sell products from an existing cabinet or cooler without having to purchase a traditional vending machine.

[0037] Some embodiments described herein relate to a handle 100 for a product sales system 200. The handle 100 includes a digital display 122 for displaying instructions and / or product information to a consumer. The handle 100 further includes a payment processing unit 140 configured to receive a payment source from a consumer to purchase a product. The handle 100 may be integrally formed with or retrofitted to a cabinet 220 for storing products 400 available for purchase. In operation, the door 224 of the cabinet 220 is configured to unlock when an authorized user is detected, which may be, for example, when a payment is received or detected by the payment processing unit 140. In response to detection of an authorized consumer, the consumer may select a product in the cabinet 220 for purchase. A product removed from the cabinet 220 is automatically identified by a product sensor 270 of the cabinet 220, and the display 122 of the handle 100 may show product information corresponding to the removed product. When the consumer has finished selecting the products, the consumer may close the door 224 of the cabinet 220 and complete the purchase on the digital display 122 of the handle 100 .

[0038] In some embodiments, a handle 100 for use with a product vending system 200 includes a housing 110, a display 122 disposed on the housing 110, a control unit 150 for controlling the operation of the product vending system 200, and a payment processing unit 140 disposed on the housing 110 and configured to detect a payment source, as shown in FIG. 1 . In some embodiments, the housing 110 may enclose the control unit 150 and other components of the handle 100. In some embodiments, the control unit 150 may be electrically connected to the housing 110 of the handle 100 and its components and may be located external to the housing 110. For example, the control unit 150 may be located on or within the cabinet 220 or the door 224 of the cabinet 220. The housing 110 of the handle 100 may have a generally rectangular shape. However, the housing 110 of the handle 100 may be formed to have any of a variety of shapes, including, but not limited to, square, circular, semicircular, wedge-shaped, U-shaped, and L-shaped. When the handle 100 is secured to the door 224 of the cabinet 220, the handle 100 is configured to extend from a surface of the door 224 so that the handle 100 can be grasped by a consumer to open the door 224 of the cabinet 220.

[0039] In some embodiments, the display 122 may be located on the front 112 of the housing 110 of the handle 100. The display 122 may show instructions for operating the product vending system and may also show product information to the consumer during the product vending operation. The display 122 may include a liquid crystal display (LCD), a light emitting diode (LED) display, or an organic light emitting diode (OLED) display, among other types of displays known in the art. In some embodiments, the display 122 may be part of the user interface 120 for receiving user input. The display 122 may be a touchscreen display such that a consumer may touch a portion of the display 122 to enter user input.

[0040] The display 122 may be configured to display a graphical user interface (GUI) 130 for a product vending system, as shown in FIG. 2 , for example. The GUI 130 may provide instructions for operating the product vending system in which the handle 100 is installed. The GUI 130 may display text, images, or video providing information about the product vending system. For example, the instructions may include text 136 describing steps for purchasing a product, such as providing a payment source, selecting a product, and completing a purchase. Each step may also include corresponding images 134 or animations depicting the consumer providing a payment source, selecting a product, and completing a purchase. Additionally, the GUI 130 may display one or more icons for receiving user input, such as an input to confirm a product selection or complete a product purchase. In embodiments with a touchscreen display, a user may touch a portion of the display 122 where an icon is displayed to enter user input. In some embodiments, the user interface 120 may further include one or more actuators for receiving user input, such as a push button, lever, dial, switch, or the like. In embodiments having actuators, a user may utilize the actuators to navigate through options shown on display 122 or to enter user input.

[0041] In some embodiments, the handle 100 is configured to detect the presence of an authorized user. The presence of an authorized user may be determined, for example, in response to receiving a payment by the handle 100. The handle 100 may include a payment processing unit 140 configured to detect a payment source and receive a payment from a user, as shown in FIG. 1 . The payment processing unit 140 is disposed on the housing 110 of the handle 100 and may be configured to detect and receive one or more types of payments. The payment processing unit 140 may include a magnetic stripe reader 142 for reading credit cards, debit cards, gift cards, ATM cards, etc., a chip reader 144 for reading credit cards, debit cards, and other debit cards with an electronic chip, i.e., chip cards (e.g., Europay, Mastercard, and Visa (EMV) chip reader), and a near field communication (NFC) reader 146 for contactless payments. The payment processing unit 140 may also be configured to receive mobile payments, such as payments made using Apple Pay or Google Pay, and may include an RFID sensor configured to read or detect RFID tags, or a QR code reader configured to scan QR codes or barcodes displayed on printed membership cards, shopping bags, bottles, among other items, or QR codes on a mobile device, such as a software application (or "app") on a mobile device. Additionally, the payment processing unit 140 may be configured to receive an indication that a consumer has made a payment, such as a remote payment or a payment made on a smartphone or smartphone application, and the remote payment indication is transmitted to the handle 100 to enable the consumer to purchase a product without entering a payment at the handle 100 of the beverage dispensing system.

[0042] In some embodiments, an authorized user may be determined by entering a user's identification information, such as by entering the user's name where the user's name is stored in a database, scanning an identification such as a driver's license or passport, or entering an identification code. Additionally, the handle 100 may include a biometric sensor 170 (see FIG. 3 ) configured to determine the consumer's identity and thus the presence of an authorized user. The consumer's identity may be tied to a payment source, such that, in response to the consumer's identification, the consumer's payment source can be automatically accessed to purchase products. The biometric sensor 170 may be configured to identify an individual based on a fingerprint, palm print, retina, iris, face, or facial features, among other biometrics.

[0043] In some embodiments, handle 100 includes indicator light 160, as shown in FIG. 1 . Indicator light 160 may be, for example, one or more light emitting diodes (LEDs). Indicator light 160 is configured to indicate the status of a product dispensing operation. Indicator light 160 may be configured to illuminate in a manner that indicates one or more different steps in the product dispensing operation. In embodiments, indicator light 160 may illuminate in different colors and may blink or flash to provide additional visual feedback to the consumer during the product dispensing operation. For example, indicator light 160 may illuminate a first color, such as green, when product vending system 200 is available for use, indicator light 160 may illuminate a second color, such as blue, when product vending system 200 is in use, and indicator light 160 may illuminate a third color, such as red, to indicate an error, such as a declined payment, the detection of an unauthorized item in storage compartment 235, or to provide a warning to indicate that a purchase is about to be completed or that door 224 of cabinet 220 is about to lock.

[0044] In some embodiments, the audio unit 190 may be configured to emit or generate an audible alert or tone. The audio unit 190 may be located on or within the housing 110 of the handle 100, or may be positioned external to the handle 100, such as in a portion of the cabinet 220 or the door 224 of the cabinet 220. In such embodiments, the audio unit 190 may be in wired or wireless communication with the handle 100. The audio unit 190 may include memory for storing one or more pre-recorded sounds, tones, or messages, among other audible alerts. The audio unit 190 may be configured to play a greeting or welcome to the consumer upon detection of the consumer or upon receipt of a payment source. Additionally, the audio unit 190 may play a message to thank the consumer upon completion of a purchase. As discussed in more detail below, the audio unit 190 may also be configured to generate an alert when a product is removed from or returned to a product storage compartment of a product vending system.

[0045] Product vending system 200 includes a handle 100 described herein and a product storage cabinet 220, as shown, for example, in Figure 4. Cabinet 220 defines a product storage compartment 235 for storing product 400 and includes a door 224 movably connected to storage compartment 235, whereby door 224 can move between a closed configuration, in which the product in storage compartment 235 is enclosed within cabinet 220 and inaccessible to consumers, and an open configuration, in which door 224 slides or pivots away from storage compartment 235 to allow consumers to access product 400 therein. Cabinet 220 can have any of a variety of geometric shapes, such as a rectangular prism, a cube, a cylinder, or the like, or cabinet 220 can have a cross-sectional area that is semicircular, triangular, or elliptical, among other cross-sectional shapes. Cabinet 220 may store any of a variety of products, such as beverages, including canned or bottled beverages, or food products such as bags of chips or pretzels, energy bars, candy, cookies, granola bars, snack mixes, and protein bars, among other food or beverage products. Cabinet 220 may also store products such as reusable containers or bottles, e.g., water bottles or sports bottles, for consumer purchase. In some embodiments, door 224 of cabinet 220 may include a transparent portion 226 so that a consumer can view product 400 in storage compartment 235 without having to open door 224. Door 224 may be pivotally connected to cabinet 220 by a hinge, or door 224 may slide on a track in cabinet 220.

[0046] In some embodiments, storage compartment 235 may be a temperature-regulated compartment, such as a refrigerated compartment, for storing perishable food or beverage products, such as dairy-based products, produce, or for maintaining food or beverage products at low temperatures. In such embodiments, cabinet 220 may be a refrigerated cooler that includes a cooling unit, such as a vapor compression or thermoelectric refrigeration system, for maintaining storage compartment 235 at a predetermined temperature for storing food and beverage products. In some embodiments, cabinet 220 may not have a dedicated cooling unit, but may be insulated and / or provide passive cooling. Cabinet 220 need not be a refrigerated compartment and may be maintained at ambient temperature if used to store products such as chips, pretzels, candy, cookies, granola bars, protein bars, energy bars, among other products that do not require refrigeration.

[0047] In some embodiments, the cabinet 220 includes a lock 240 (see FIG. 3 ) to maintain the door 224 in a closed configuration to prevent unauthorized users from accessing the storage compartment 235 and the products 400 therein. The lock 240 may be an integral part of the existing cabinet 220, or the lock 240 may be obtained separately and installed on the door 224 of the cabinet 220 to form the product vending system 200. The lock 240 may be, for example, an electromagnetic lock or an electromechanical lock, among other types of locks. The lock 240 may be in communication with the control unit 150 of the handle 100 such that the handle 100 can control the operation of the lock 240.

[0048] The cabinet 220 may also include a cabinet light 250 (see FIG. 4 ) within the storage compartment 235 that illuminates the storage compartment 235 to allow for easier viewing of the products 400 therein. The cabinet light 250 may be, for example, one or more LEDs, incandescent bulbs, fluorescent lights, or arc lamps. The cabinet light 250 may be an integral part of the cabinet 220, or the cabinet light 250 may be obtained separately and installed in the cabinet 220 to form the product vending system 200.

[0049] In some embodiments, the product sales system 200 includes one or more product sensors 270 configured to detect when a product 400 is removed from or returned to a storage compartment 235 of a cabinet 220. In some embodiments, the product sensor 270 can be an optical sensor, such as a camera, configured to detect and identify a product removed from the cabinet 220. For example, the optical sensor can capture video of the product as it passes the sensor while being removed from or inserted into the storage compartment 235 and compare the product in the captured video to an image library, such as an edge or cloud-based image library. Alternatively, the optical sensor can capture images of the product in the storage compartment before and after a consumer purchase to determine which product has been removed. However, as will be readily understood by one of ordinary skill in the art, various types of sensors 270 can be used to detect the removal and return of a product 400 from and to the cabinet 220. For example, other types of sensors 270 that can be used instead of or in addition to optical sensors include weight sensors to determine the weight of products in a storage compartment before and after product removal, or radio frequency identification (RFID) tags and RFID readers / scanners to detect product removal and return. In some embodiments, product sensor 270 may identify products by detecting the shape and / or color of the product being removed from cabinet 220. Product sensor 270 may be positioned adjacent door 224 on a front portion of storage compartment 235, such as a corner of storage compartment 235 or on a shelf 232 of storage compartment 235. Product sensor 270 may define a plane parallel to the front of cabinet 220 and detect when product 400 passes through the plane, indicating that product 400 has been removed from or returned to cabinet 220.

[0050] In some embodiments, the handle 100 may be retrofitted to an existing cabinet 220, thereby converting the cabinet 220 into a product vending system 200 for storing products upon installation of the handle 100. In this manner, any of a variety of types and styles of cabinet 220 may be converted into a product vending system for selling products to consumers by installing the handle 100. The handle 100 may be secured to the door 224 of the cabinet 220 having the storage compartment 235 via mechanical fasteners such as bolts or screws, or may be secured using adhesives or epoxies, among other fastening methods. Additionally, one or more of lock 240, cabinet light 250, and product sensor 270 may be installed in cabinet 220 to form product dispensing system 200, or cabinet 220 may already include one or more of lock 240, cabinet light 250, and product sensor 270. Handle 100 may be positioned in communication with lock 240, cabinet light 250, and product sensor 270 via wired or wireless communication to control the operation of product dispensing system 200.

[0051] However, in some embodiments, the handle 100 may be integrally formed with or built into the cabinet 220. The handle 100 may be integrally formed with the door 224 of the cabinet 220, as shown in FIG. 4, and may be located on the side of the door 224 opposite the hinged side of the door 224.

[0052] A control unit 150 of the handle 100 coordinates the operation of the product vending system 200, as shown in FIG. 3 . In some embodiments, a single control unit 150 may control the operation of all components of the product vending system 200. In some embodiments, more than one control unit 150 may be used, with multiple control units 150 being used to control different operations or components of the product vending system 200. For example, a first control unit may control a payment processing unit and a digital display, while a second control unit may control the operation of door locks, cabinet lights, and / or product sensors. It is understood that multiple control units 150 may be used, but for convenience, the description herein will primarily relate to embodiments having a single control unit 150.

[0053] The control unit 150 of the handle 100 may be placed in communication with the lock 240 of the cabinet 220, such as by wired or wireless communication. For example, the handle 100 and the lock 240 may be connected by a wire extending through the frame of the door 224 of the cabinet 220 to provide a seamless appearance. The control unit 150 may be configured to disengage the lock 240 of the cabinet 220 when an authorized user is detected, such as when a payment or payment source is received or detected, so that the user can open the door 224 of the cabinet 220 and select from the products 400 in the storage compartment 235 of the cabinet 220.

[0054] The control unit 150 may communicate with the cabinet light 250 to control the illumination of the cabinet light 250. The control unit 150 may increase the brightness or intensity of the cabinet light 250 when the door of the cabinet 220 is opened. Increasing the brightness of the cabinet light 250 may assist in allowing a consumer to determine that a product purchase operation is in progress, allowing the consumer to more easily view the products 400 stored in the storage compartment 235, and facilitating the operation of the product sensor 270 in identifying the products. The control unit 150 may turn off or dim the cabinet light 250 when the product vending system 200 is not in use to conserve energy.

[0055] The control unit 150 may communicate with the product sensor 270 to receive information regarding the removal and return of products from the storage compartment 235. The control unit 150 may store information regarding products in the storage compartment 235 of the cabinet 220. The control unit 150 may cause the display 122 of the handle 100 to display product information regarding products determined by the product sensor 270 to be removed from the cabinet 220, as shown in FIG. 5 . The displayed product information may include the type or name of the removed product and the price of the removed product. As the consumer removes products 400 from the storage compartment 235, the display 122 of the handle 100 may show product information 137 regarding each removed product and may also show a virtual shopping cart. The display 122 may show an image of the removed product, the price of the removed product, the name, type, or brand of the removed product, and a total price 139 of all removed products. The display 122 may provide real-time updates of the consumer's removal and return of products from the storage compartment 235. If the display 122 of the steering wheel 100 is a touchscreen display, the display 122 may be configured to show an icon 135 for completing the purchase of any items in the virtual shopping cart. The consumer may touch the display at the location of the icon 135 to complete the purchase. In some embodiments, the icon 135 may require the consumer to perform a gesture, such as swiping on the display 122 from left to right along a path or track, to complete the purchase. Requiring a gesture may help prevent a user from accidentally completing a purchase by unintentionally pressing on the display 122 at the location of the icon 135.

[0056] In some embodiments, the product sales system 200 may further include a product information display 280, as best shown in FIG. 4 . The product information display 280 is configured to display information about the product 400 removed from the cabinet 220, such as the brand of the product, such as Pepsi, the type of product removed, the weight of the product (e.g., ounces or grams), the volume of the product (e.g., milliliters), the price of the product, and the total amount of all products removed. The product information display 280 may be located within a storage compartment 235 of the cabinet 220, such that the display 280 is easily visible while a consumer is selecting products 400 from the cabinet 220 for purchase. For example, the product information display 280 may be located on one or more shelves 232 within the cabinet 220. The product information display 280 may be an alphanumeric display that simply displays alphanumeric characters. However, the product information display 280 may be an LCD, LED, OLED display, or electronic ink (e-ink) display, among other types of displays. Product information display 280 allows a consumer to easily determine the price of a product (or other information about the product) by removing the product from storage compartment 235 of cabinet 220 and viewing the price and other product information on product information display 280.

[0057] The product information display 280 may display product information that is also displayed on the digital display 122 of the handle 100. Thus, the product information display 280 and the digital display 122 of the handle 100 may simultaneously display product information. In some embodiments, the digital display 122 of the handle 100 displays product information when the door 224 of the cabinet 220 is closed, and when the door 224 is open, the digital display 122 of the handle 100 is dimmed or turned off, and the product information is instead displayed on the product information display 280. For example, the digital display 122 may be dimmed or turned off when the door 224 is rotated 90 degrees or 180 degrees to an open configuration, rotating the face of the handle 100 and the display 122 away from the user. This may prevent the user's personal information (e.g., account information, product purchase information, etc.) from being publicly displayed, thus providing additional privacy for the user. When the door 224 is closed, the product information display 280 is dimmed or turned off and the product information is displayed on the digital display 122 of the handle 100.

[0058] In some embodiments, control unit 150 may store and track an inventory of products in storage compartment 235. The product inventory may be automatically updated when product removal and return to storage compartment 235 is detected by product sensor 270. Because the product inventory is known, control unit 150 may determine when an unknown item is inserted into cabinet 220. For example, a consumer may accidentally leave an item in cabinet 220 while selecting a product, or a consumer may insert an unknown item into storage compartment 235 to attempt to avoid paying for the removed product by providing the appearance that the removed product was returned. If product sensor 270 determines that an unknown item has been inserted into cabinet 220, or if the number of items returned to cabinet 220 exceeds the number of products removed from cabinet 220, control unit 150 may prevent completion of the purchase until any unknown items are removed from cabinet 220.

[0059] An exemplary method of operating a product vending system 600 including a handle described herein is shown in FIG. 6. When not in use, the product vending system is idle (610) and the cabinet door is locked. The handle's display may display instructions for initiating a product vending operation, such as a prompt to enter a payment. A consumer may approach the product vending system, which unlocks the cabinet door upon detecting the presence of an authorized user (620). For example, an authorized user may be detected when the handle's payment processing unit detects a payment source, such as when a consumer swipes a credit card in the handle's credit card reader, taps a credit card or mobile payment card for contactless payment, or inserts a credit card chip into the handle's chip reader. Alternatively, an authorized user may be detected by a biometric sensor in the handle or when the handle receives an indication that a user has made a remote payment, such as paying through a software application on a mobile device.

[0060] If an authorized user is detected, the cabinet door is unlocked, and the consumer may open the door and select products from the cabinet for purchase (630). The consumer may remove one or more products from the cabinet, and as the products exit the cabinet, product sensors, such as one or more cameras in the cabinet, detect the number and type of products removed (640). Product information about the products removed from the cabinet is displayed (650). A display on the handle may display product information such as the number, type, product price, and total cost of the products removed. In embodiments with a product information display, the product information display may show the type or name of the product removed, the price of the product removed, and the total cost of the product removed. The cabinet product sensor may determine whether the removed product is subsequently returned to the cabinet (660). For example, a consumer may remove a product from the cabinet and view the product information display to determine the price of the product. If the consumer does not agree with the price, the consumer may return the product to the cabinet. Alternatively, a consumer may remove two different products from the cabinet and examine the products, such as to compare nutritional information or ingredients, and the consumer may choose to return one of the products and purchase the product they prefer.

[0061] Once the consumer has finished selecting the products, the cabinet door is closed (670). Product information about the removed products is displayed on the handle display. The product information may include the product brand, product type or name, product price, and total price of the removed products. If desired, the consumer may reopen the door and continue selecting products. Closing the door may complete the purchase of the removed products (680). To confirm and complete the purchase, it may be necessary to detect a payment source, such as by swiping or inserting a credit card into the reader a second time. Alternatively, the display may present a graphical user interface that prompts the consumer to make a gesture on the display, such as swiping from left to right to confirm the purchase. In some embodiments, once the door is closed, the purchase may be automatically completed after a predetermined amount of time (e.g., 10 seconds) has elapsed. Once the consumer confirms the purchase, the payment source is charged the total price of the removed products (or the purchase price is paid to their account), and the cabinet door is locked to secure the products within the cabinet.

[0062] Because the consumer is required to enter a payment source to unlock the cabinet door, the consumer may be charged for any products removed and may not be able to remove the products without paying. Additionally, once the consumer's payment source is entered, the consumer is reminded to ensure the cabinet door is closed and locked upon completion of the purchase to avoid further charges.

[0063] A further exemplary method of operating a product vending system 700 including a cabinet light and audio unit is shown in FIG. 7. When not in use, the cabinet of the product vending system is locked and the cabinet light is turned off or dimmed to conserve energy (710). An indicator light on the handle may be illuminated a first color, such as green, to indicate to potential customers that the product vending system is available for use. The presence of an authorized consumer may be detected (720), such as when the consumer enters a payment into the handle's payment processing unit. The handle's audio unit may generate an audible alert to welcome the user and to indicate that a payment has been detected or received and accepted. The indicator light may then be illuminated a second color, such as blue, to indicate that a vending operation is in progress.

[0064] In response to detecting an authorized user, the cabinet door may be unlocked and the brightness or intensity of the cabinet light may be increased (730) to allow the consumer to more easily view the products in the storage compartment. Increasing the brightness of the cabinet light also allows the product sensor to more easily identify products removed from or inserted into the cabinet's storage compartment. In some embodiments, the cabinet light may provide lighting effects, such as flashing or illuminating with different colors, to provide entertainment to the user and to indicate that a product sale operation is in progress. Because the handle display is positioned on the door, the display faces away from the consumer when the door is open. When the door is open, the display may automatically turn off or dim to prevent third parties from viewing information about the consumer's purchase and to conserve energy. The audio unit may generate an audible alert when a product is removed from the storage compartment (740). The audio unit may play a first tone when the product is removed and a second tone when the product is returned to the cabinet. The second tone may be the same as or different from the first tone. In some embodiments, the second tone may be the inverse or opposite of the first tone. For example, if the first tone is an ascending tone, the second tone may be a descending tone. A tone may be played for each product removal or return, such that if two products are removed, two tones may be played, and if the consumer returns only one of the two products to the cabinet, a single tone may be played to indicate the return of one product to the cabinet. The audible alert may allow the consumer to easily verify that the removal of the product was detected and that the consumer will be charged for the removed product; similarly, the audible alert may allow the user to verify that the return of the removed product was recognized by the product vending system. Additionally, the audible alert may be beneficial to consumers with visual impairments and may enhance the consumer's product purchasing experience.

[0065] When the door is closed (750), the handle's digital display may increase brightness or intensity, show product information about the removed product, and complete the purchase of the removed product (760). Additionally, when the door is closed, an indicator light may illuminate a third color, such as red, to provide a warning or alert to the consumer that the purchase is about to be completed. In some embodiments, the purchase may be completed upon receipt or detection of a payment source at the handle or upon receiving user input at the handle's display. In some embodiments, the purchase may be completed automatically after a predetermined period, such as 10 seconds. In such embodiments, the handle's indicator light may flash or change to red to indicate that the purchase is about to be completed or that the cabinet door is about to be locked. An audio unit may play an alert or message to confirm the completion of the purchase and thank the customer for purchasing the product. When the purchase is completed (770), the cabinet lights may be dimmed or turned off to conserve energy. The handle's indicator light may illuminate a first color, such as green, to indicate that the product vending system is available for use.

[0066] In some embodiments, the display 122 of the handle 100 may remain idle when the product vending system 200 is not being used, and the display 122 of the handle 100 may be dimmed or turned off to conserve energy. However, in some embodiments, the display 122 of the handle 100 may include a consumer attraction mode. In the consumer attraction mode, the display 122 may show advertising, such as messages, images, or videos about the products and product brands being sold to attract the interest of consumers in the nearby area. The product vending system 200 may include a proximity sensor 180 that detects when a consumer is within a predetermined distance of the product vending system 200. When the proximity sensor 180 determines that the consumer is near the product vending system 200, the display 122 may exit the consumer attraction mode and display a welcome animation or instructions for operating the product vending system 200 as discussed herein. When the consumer completes a purchase using the product vending system 200, the display 122 may automatically return to the consumer attraction mode.
