Kiosk Remote Order Authentication via PIN and Beacon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional post-mix beverage dispensing systems face challenges in providing a wide variety of beverages in a compact footprint, and there is a need for efficient authentication and fulfillment of remote orders at kiosks.
Innovation Solution
The system includes a beverage vendor with a nozzle for dispensing beverage ingredients, a user interface for displaying pending orders, and a controller for authenticating orders through PIN codes or server authentication, enabling secure and efficient dispensing of customized beverages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional post-mix beverage dispensing systems are used, then beverage dispensing is achieved, but the system occupies a large footprint and cannot provide a wide variety of beverages in a compact space
Solution Approach 1:
The system segments beverage ingredients into concentrated micro-ingredients stored in cartridges, separating storage from dispensing functions. This allows multiple beverage varieties to be achieved through digital combination of concentrated ingredients rather than requiring separate dispensing systems for each beverage type, significantly reducing the physical footprint while maintaining high adaptability.
Solution Approach 2:
The system transitions from physical variety (multiple separate beverage containers) to digital variety (software-controlled combination of concentrated ingredients). By moving the beverage differentiation to the digital/control dimension rather than the physical dimension, the system achieves wide beverage variety in a compact footprint.
2Ease of operation
If remote ordering is implemented without authentication, then user convenience is improved, but order security and accuracy deteriorate
Solution Approach 1:
The system performs preliminary authentication actions during order placement through multiple mechanisms: beacon-based proximity verification ensures the customer is physically present at the correct kiosk, PIN code verification provides cryptographic authentication, and order pre-configuration reduces errors. These preliminary security measures are integrated seamlessly into the remote ordering workflow, maintaining convenience while ensuring reliability.
Solution Approach 2:
The system introduces intermediary authentication mechanisms (beacon signals, PIN codes, server verification) that mediate between the customer's remote order request and the beverage dispensing action. These intermediaries verify identity and intent without requiring the customer to be physically present at the kiosk during ordering, thus maintaining convenience while ensuring security.
3Reliability
If multiple authentication methods are implemented, then order security is improved, but system complexity increases
Solution Approach 1:
The controller serves multiple functions: it manages beverage dispensing, handles authentication requests, communicates with beacons and servers, and controls the user interface. By making the controller universal and multi-functional, the system achieves high security through multiple authentication methods without proportionally increasing overall system complexity, as a single component performs diverse security-related tasks.
Solution Approach 2:
The system implements self-service authentication mechanisms where the customer independently provides their PIN code or approves the transaction through their mobile device. This self-service approach to authentication reduces the need for complex manual verification procedures and staff intervention, achieving high security while keeping operational complexity manageable.

AI summary
A kiosk maintains a list of pre-paid orders. A first authentication process enables a consumer to select their order on the kiosk so as to receive the product or service that was remotely paid for via a mobile application. Authentication of the consumer selecting the order is performed based upon sending an order authentication notification to the mobile application that completed the order. If the user of the mobile application provides a positive authentication reply, the kiosk is unlocked to fulfill the order. The consumer may alternatively be authenticated by providing a personal identification number (PIN) that is associated with the order or associated with a user of the mobile application. Authentication using the PIN enables a consumer to interact with the kiosk to receive the previously ordered product or service without having to access their mobile phone or mobile application that was used to place the order.
