POS Terminal Multi-Interface Payment Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems lack flexibility and standardization, particularly for store-branded and pre-paid accounts, as they often require multiple interfaces and protocols, and do not efficiently manage value-added services or secure transactions.
Innovation Solution
A point of sale (POS) terminal with multiple interfaces, including NFC, NFC P2P, and QR code readers, and a payment device with a processor and secure element, capable of host card emulation, that can transmit data in a standardized format using multiple interfaces and protocols, and manage value-added services through extensible tagged formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple interfaces and protocols are used for different payment devices, then the system can accommodate various account types (store-branded, pre-paid, etc.), but the device complexity increases
Solution Approach 1:
The POS terminal is designed with multiple communication interfaces (NFC, QR code reader, chip card reader) that can handle different payment device types through a unified architecture. This allows the terminal to universally accept various account types including store-branded and pre-paid accounts without requiring separate dedicated systems for each payment method.
Solution Approach 2:
The patent introduces a standardized data format and protocol layer that acts as an intermediary between diverse payment devices and the processing system. This intermediary layer translates different interface protocols into a common format, reducing the apparent complexity by providing a unified interface for handling multiple account types.
2Adaptability or versatility
If value added service information is transmitted in extensible tagged format, then the system flexibility increases, but the data processing complexity increases
Solution Approach 1:
The system uses extensible tagged formats for VAS information that can dynamically adapt to different service requirements. The tagged format allows the data structure to be flexible and extensible, accommodating various value-added services without requiring a complete redesign of the data protocol, thus managing complexity through dynamic adaptability.
Solution Approach 2:
Value added service information is segmented into distinct tagged fields that can be independently processed and routed to different destinations. This segmentation allows the system to handle complex VAS data by breaking it into manageable, standardized units that can be processed efficiently through the extensible format.
3Adaptability or versatility
If payment data is transmitted through multiple protocols, then the reachability of payment devices increases, but the transaction processing time increases
Solution Approach 1:
The POS terminal is pre-configured with multiple communication interfaces and protocol handlers ready to operate simultaneously. When a payment device is presented, the terminal can immediately attempt communication through the appropriate interface without requiring protocol negotiation or switching delays, thus reducing transaction processing time while maintaining broad device reachability.
