AI Technical Summary

Technical Problem

Existing FLASH storage IC cards suffer from shortened lifespan and reduced transaction performance due to frequent cross-page erase and write operations, impacting user experience and issuing bank costs.

Method used

The configuration instructions are parsed during the preprocessing stage to determine the functions supported by the IC card and the data that needs to be updated synchronously. The storage space is then allocated to the same or adjacent FLASH storage pages. Differentiated space creation and data writing strategies are adopted to reduce cross-page erasure and writing, extend the service life, and improve transaction performance.

Benefits of technology

It effectively extends the lifespan of IC cards, reduces the costs for issuing banks, improves transaction performance and user experience, and optimizes storage space utilization.

Abstract

The application relates to the technical field of smart card data storage, and discloses a method and system for optimizing the service life and performance of a FLASH storage type IC card. In a preprocessing stage, a configuration instruction is received, a function identification parameter in the configuration instruction is analyzed, the functions supported by the IC card and data needing to be synchronously updated are determined, and the storage spaces of the data needing to be synchronously updated in the same transaction are allocated to the same or adjacent FLASH storage pages. In a data writing stage, for the data written in a personalization stage, a differentiated strategy is adopted according to the synchronous updating attribute and length variability of the data: the storage space of the synchronously updated data is created in the preprocessing stage, the storage space of the non-synchronously updated data is created when a writing instruction is received, and the current storage length value of the variable length data needs to be recorded. The method can optimize storage utilization, improve the performance and service life of the IC card, reduce the cost of the card issuing bank, and improve the customer use experience.
