Biometric Payment System Using Wireless Device Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment methods, such as QR code payments and biometric feature recognition, are inconvenient and time-consuming, especially in public transport where quick payment is necessary, as they rely on mobile devices and require matching biometric features with all stored samples, leading to processing delays.
Innovation Solution
A payment system using wireless communication and biometric features that associates a wireless communications device with a biometric feature, allowing the payment collection system to recognize the device and match the user's biometric feature with the corresponding account without needing to match it with all stored features, enabling quick account determination and deduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If QR code or bus card payment is used, then payment can be made with mobile devices, but users need to carry payment devices and operate them on card reader machines, affecting convenience
Solution Approach 1:
The system enables self-service payment by automatically recognizing the user's wireless communication device and matching biometric features without requiring manual device operation. The payment collection system autonomously completes the payment process by matching the collected biometric feature with stored features, eliminating the need for users to actively operate payment devices.
Solution Approach 2:
The patent replaces manual mechanical operations (swiping bus cards, scanning QR codes) with automated biometric recognition and wireless communication. The system uses automatic device recognition and biometric feature matching to substitute the mechanical interaction between user and payment device.
2Reliability
If QR code-based verification is used, then payment can be made through mobile devices, but when mobile devices are powered off, users cannot take a bus
Solution Approach 1:
The system introduces wireless communication devices and biometric features as intermediaries between the user and the payment system. These intermediaries remain functional even when mobile devices are powered off, ensuring continuous payment availability. The biometric feature serves as a reliable mediator that does not depend on device power state.
Solution Approach 2:
The system performs preliminary actions by pre-storing biometric features and device identifiers in the payment collection system before the actual payment moment. This preliminary preparation ensures that payment can be executed immediately when the user approaches, without requiring active mobile device participation at the moment of payment.
3Measurement precision
If biometric feature matching is performed with all stored samples, then accurate user identification can be achieved, but processing delays occur
Solution Approach 1:
The system segments the biometric recognition process into two stages: first, rapid device identification through wireless communication to narrow down the search scope; second, biometric feature matching only within the narrowed scope. This segmentation significantly reduces processing time while maintaining recognition accuracy by avoiding comparison with all stored samples.
Solution Approach 2:
The system performs preliminary device recognition and account identification before biometric feature matching. By first identifying the user's wireless communication device and pre-fetching associated account information, the system prepares the recognition process in advance, reducing the time required for actual biometric comparison.

AI summary
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for payment based on wireless communication and biological features. One of the methods includes determining at least one wireless communications device is within a wireless communication range of a payment collection system. Data specifying at least one account associated with the at least one wireless communications device and data specifying a biometric feature associated with the at least one account is obtained from a payment platform. The payment collection system collects a target biometric feature of a target user. In response to determining that the target biometric feature matches the biometric feature associated with the at least one account, a target account of the target user is determined based on the at least one account, and a deduction operation is performed on the target account.
