NFC Portable Device Transaction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for frictionless shopping experiences are complex to design, develop, and secure, and they generate significant network load and carbon footprint due to constant communication with back-end systems.
Innovation Solution
The use of Near Field Communication (NFC) capable portable devices that are not connected to the Internet, allowing for frictionless transactions within a closed, local area network at resource provider locations, where items picked by users are associated with the device and charged automatically upon checkout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional frictionless shopping systems (AI cameras, smart IoT devices, purpose-built payment terminals) are deployed, then the shopping experience becomes frictionless, but the system complexity and security requirements increase significantly
Solution Approach 1:
The patent extracts the payment terminal functionality from the shopping system, removing it entirely from the store environment. Instead of deploying complex payment terminals throughout the retail location, the system uses portable devices that customers bring themselves, thereby eliminating the need for sophisticated in-store payment infrastructure while maintaining frictionless checkout
Solution Approach 2:
The patent uses portable devices (smartphones, wearables, tablets) as copies or substitutes for purpose-built payment terminals. These existing consumer devices already possess the necessary processing power and security features, eliminating the need to deploy specialized terminal hardware throughout the retail location
2Reliability
If purpose-built payment terminals with security features (tamper-resistance, tamper-responsiveness) are deployed, then transaction security is improved, but the cost and complexity of security evaluation and compliance increase
Solution Approach 1:
The patent leverages the universal security features already present in modern portable devices (biometric authentication, encrypted storage, secure elements) that were designed for multiple purposes. These devices already meet or exceed payment terminal security requirements without requiring separate security evaluation and certification processes
Solution Approach 2:
The portable devices perform self-authentication and self-securing of transaction data using their built-in security features (fingerprint sensors, facial recognition, secure enclaves). The devices automatically manage their own security credentials and encryption keys without requiring external security infrastructure or compliance verification
3Ease of operation
If AI powered cameras transmit video images to back-end systems for real-time analysis, then frictionless shopping experience is enabled, but network bandwidth consumption and carbon footprint increase significantly
Solution Approach 1:
The patent removes the need for continuous video transmission and real-time back-end analysis by using portable devices that independently process and validate transaction data. The system extracts the analytical function from the back-end and performs it locally on the customer's device, eliminating gigabytes of network traffic
Solution Approach 2:
The portable device acts as an intermediary between the customer and the retail system, performing local validation and processing of transaction data. This intermediary function eliminates the need for continuous communication with back-end systems, reducing network bandwidth consumption while maintaining transaction accuracy
4Reliability
If PIN entry or delay in processing is introduced for security, then transaction security is improved, but the shopping experience becomes frictioned and impulse-based shopping is inhibited
Solution Approach 1:
The system performs preliminary authentication and security validation before the customer enters the store or begins shopping. Biometric data is captured and verified in advance, and the portable device is pre-authenticated with the retail system, so that no additional security steps are required during the actual shopping or checkout process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the complexity and cost of security measures, decreases network communication bandwidth and latency, and provides a seamless, low-friction shopping experience while minimizing environmental impact.
Implementation Method 1
The portable device may be a simple device (e.g., a 'dumb' device), such that the portable device is not connected (or is not capable of being connected) to the Internet, and is not configured to communicate with external entities outside the confines of the resource provider location. The portable device (e.g., a wearable device, a physical token) may be temporarily associated with a user account at the resource provider location.
Data Source
AI summary
Embodiments are directed to using an NFC capable portable device to conduct a transaction at a resource provider location. The portable device (e.g., a wearable device, a physical token) may be temporarily associated with a user account at the resource provider location. The resource provider location includes one or more terminals that are configured to generate a list of items (e.g., items picked by the user) to be associated with the portable device. At checkout, the user surrenders the portable device, items on the list get automatically charged to the user account, and the user leaves the resource provider location. All communication between terminals, portable device and the resource provider computer occurs over a closed, local area network. Among the terminals, portable device and the resource provider computer, the resource provider computer is the only device configured to communicate with external entities over an external network.
