HCE NFC Fare Payment Routing for Public Transit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fare payment methods for public transportation are inconvenient for users, requiring complex operations such as unlocking screens, starting applications, and scanning QR codes, which can result in low success rates, especially in low-light conditions.
Innovation Solution
Implementing a fare payment method using host-based card emulation (HCE) on terminal devices, where an application establishes an NFC connection with a collection device upon receiving an HCE-based routing instruction, allowing payment-related data to be transmitted directly for verification and fare deduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QR code scanning is used for fare payment, then payment information can be transmitted, but the operation process becomes complex and success rate decreases
Solution Approach 1:
The patent extracts the payment information transmission function from the QR code scanning process and implements it through NFC technology. The terminal device directly transmits payment data to the collection device via NFC communication, eliminating the need for QR code generation, display, and scanning operations, thereby simplifying the user操作流程 and improving success rate.
Solution Approach 2:
The patent replaces the optical-based QR code scanning mechanism with an electromagnetic-based NFC communication mechanism. Instead of using camera-based optical recognition, the system uses near-field communication to transmit payment data wirelessly, which is more reliable and requires fewer user operations.
2Reliability
If QR code scanning is used for fare payment, then payment can be processed, but performance deteriorates in low-light conditions
Solution Approach 1:
The patent substitutes the optical scanning system with an electromagnetic communication system. NFC technology uses electromagnetic fields to transmit data, which are not affected by ambient light conditions. This eliminates the dependency on illumination intensity and ensures reliable payment processing in both bright and dark environments.
3Ease of operation
If NFC connection is established through HCE routing instruction, then payment transmission is simplified, but system complexity increases
Solution Approach 1:
The patent implements self-service through automatic routing instruction processing. When the terminal device approaches the collection device, the system automatically establishes NFC connection and transmits payment information without requiring user intervention for manual connection setup. The HCE routing instruction mechanism handles the complexity in the background while maintaining simplicity for the user.
Solution Approach 2:
The patent uses preliminary action by pre-configuring HCE routing instructions in the terminal device before payment is needed. The routing instruction contains pre-defined parameters for establishing NFC connections with collection devices, so when payment is required, the connection can be quickly established using these pre-prepared instructions, reducing both user effort and connection setup time.
