Method for dynamic aggregating multiple intelligent card function module based on memory card

Abstract

A method for gathering multi-type intelligent card function module based on storage card state includes adding function module management program and function module address chain list in flash memory of storage card, checking whether intelligent card function module is registered in storage card or not by terminal through said program and said chain list when certain intelligent card function is required to be used by user, selecting intelligent card function module by terminal through said program if it is than connecting storage card to exclusive terminal for activating function of said intelligent card.

Description

technical field [0001] The invention relates to a data storage card, in particular to a method for dynamically gathering various smart card function modules based on the storage card. Background technique [0002] With the continuous development of smart card technology, its role in people's work and life is becoming more and more important and indispensable, but it also leads to the following problems: [0003] 1. The application scenarios of smart cards are developing rapidly, and at the same time, the types and numbers of personal cards held by users are also increasing. For example, in terms of major types, there are SIM cards, bank cards, transportation cards, medical insurance cards...; for a certain type of cards, such as bank cards, the current state-owned bank cards have not yet realized the true "one card" ". If a new type of application needs to be added, it is generally necessary to add a physical IC card or magnetic card. This rapid increase in the number of ...

AI Technical Summary

Problems solved by technology

The rapid increase in the number of personal cards has brought great inconvenience to cardholders in carrying, keeping and using.

[0004] 2. Dynamic integration of smart card functions

[0012] 1. The stored data is very easy to modify. It is relatively easy to change the data recorded on the magnetic strip with a standard read / write device, but it is quite difficult to prove that the data has been modified afterwards;

[0013] 2. Smart cards are often used on automated equipment (ATM), during which visual inspection is difficult

[0014] 3. The service life of the magnetic stripe of the smart card is very short, and it is easily degaussed by the magnetic medium;

[0015] 4. The button on the smart card is easy to cause misoperation and cause inconvenience

[0016] 5. Once the functions supported by the smart card are designed, they cannot be changed
