Vending Machine Payment Bus for Secure Offline Mobile Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vending machine payment systems are merchant-centric, exposing customers' payment credentials to risk, requiring expensive and vulnerable payment machinery, and failing to scale with diverse vending machine scenarios.
Innovation Solution
A payer-centric payment system that uses a payment bus to enable mobile devices to securely handle payments, allowing customers to select and pay for products using their devices, with or without network connections, and reducing the need for costly payment machinery at vending machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If merchant-centric payment systems are used in vending machines, then payment processing can be performed, but customer payment credentials are exposed to security risks and theft
Solution Approach 1:
The patent introduces a payment gateway as an intermediary between the vending machine and the payment processor. The gateway receives payment requests from the vending machine, forwards them to the processor, and receives responses back. This intermediary architecture ensures that the vending machine never directly handles or stores sensitive payment credentials, eliminating the security vulnerability while maintaining payment processing functionality
Solution Approach 2:
The patent extracts the sensitive payment credential handling functionality from the vending machine system and places it entirely within the customer's mobile device and the payment processor. The vending machine is reduced to simply initiating payment requests without ever touching credential data, effectively removing the security risk source from the system
2Adaptability or versatility
If full-fledged payment machinery is installed in unattended vending machines, then payment processing capability is achieved, but device cost and vulnerability to theft increase
Solution Approach 1:
The patent implements a self-service payment model where the customer's mobile device performs all payment processing functions locally. The device stores payment credentials, handles authentication, and communicates with payment processors independently. The vending machine only needs to display product information and receive payment confirmation, dramatically reducing its hardware requirements and cost
Solution Approach 2:
The patent replaces the traditional mechanical payment terminal hardware with a software-based solution running on the customer's mobile device. Instead of installing card readers, displays, and processors in the vending machine, the system uses the customer's existing smartphone as the payment interface, substituting physical infrastructure with digital capabilities
3Ease of operation
If wireless peer-to-peer connections are used for mobile payments, then payment can be enabled, but connection security and reliability deteriorate in crowded environments
Solution Approach 1:
The patent introduces a centralized payment gateway server as an intermediary that coordinates all communication between vending machines and mobile devices. Instead of direct peer-to-peer connections, the gateway routes all payment requests and responses, providing a stable and reliable communication path that doesn't depend on local wireless conditions or device proximity
Data Source
AI summary
Described herein are systems and methods for mobile payment to vending machines with and without network connections and with and without product selection facilities. We propose a namespace and a payment bus: the namespace provides unique IDs for VMs, and the payment bus enables payers to pay VMs through any payment service of their choice. Embodiments of the invention cater to both online and offline VMs. The twin goals of our invention are (a) to give customers a platform for mobile payment to vending machines and (b) to enable vending machine operators to reduce their capital and operational costs.
