Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact IC card programmable read-write devices are limited in supporting multi-applications and on-line business transactions, as they can only configure one set of application parameters and do not support multiple interactions with terminals for on-line processing.
Innovation Solution
A system and method for non-contact security information interaction that allows parameter configuration for multiple applications, enabling the non-contact IC card programmable read-write device to interact with terminals and servers, supporting both off-line and on-line transactions by using processing flow identification numbers for business logic judgment and data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the non-contact IC card programmable read-write device configures one set of application parameters for a single business application, then the device can process that specific application, but it cannot support multiple applications including on-line based applications
Solution Approach 1:
The patent segments the parameter configuration into multiple independent parameter sets, each corresponding to a different application type. The terminal can select and activate specific parameter sets based on the required application, enabling multi-application support while maintaining clear separation and management of different configuration parameters
Solution Approach 2:
The read-write device is designed with universal parameter configuration capabilities that allow it to adapt to multiple different applications. By supporting configurable parameter sets for both off-line and on-line applications, the device achieves multi-functionality without requiring separate dedicated devices for each application type
2Productivity
If the read-write device performs serial port communication with the terminal, then the device structure remains simple, but the transaction speed becomes slower
Solution Approach 1:
The communication protocol is made dynamic by allowing the terminal and read-write device to negotiate and switch between different communication modes. The system can adaptively select between serial port communication and more efficient communication protocols based on the specific transaction requirements, thereby improving transaction speed while maintaining structural simplicity
3Adaptability or versatility
If the programmable read-write device processes off-line transactions with integrated business logic, then the transaction can be completed independently, but the device cannot interact with the terminal multiple times for on-line processing
Solution Approach 1:
The terminal performs preliminary actions by pre-configuring the read-write device with appropriate parameter sets and establishing communication protocols before the actual transaction. This preliminary setup enables the read-write device to flexibly interact with the terminal multiple times during on-line processing, as the necessary communication frameworks are already in place
