Problems solved by technology

[0008] The inventor found that there are at least the following problems in the prior art: the M1 card is a logical encryption card, which relies on logic circuits for calculations, so the timing of its calculations is very strict and cannot be easily changed; while in the prior art, the M1 card module is used to perform operations. Data update is required before the IC card transaction operation, which will change its original working sequence and cause the transaction to fail to proceed normally, so the existing M1 card reading and writing equipment must be updated or replaced to realize the above IC card data update method

Embodiment 1

[0040] The embodiment of the present invention provides a method for updating IC card data, in which the IC card has a CPU card module and an M1 card module; card data.

[0041] Preferably, the M1 card data and the CPU card data are any data involved in the transaction process, such as including at least one of remaining fund amount, remaining points, remaining card swiping times, and card number.

[0042] Preferably, the format of the M1 card data is the same as that of the prior art, including the M1 card master data and the M1 card secondary data, these two sets of data are consistent, so as to be mutual backups; the M1 card master data and the M1 card secondary data In , a check value for checking the correctness of the data can also be set respectively (the check value can be calculated from the data itself). The reason why the M1 card data preferably adopts two sets of data with check values ​​is because the M1 card is a logic card, which is relatively prone to errors, ...

Embodiment 2

[0058] The embodiment of the present invention provides an IC card, which includes an M1 card module 1 and a CPU card module 2, and the M1 card data used by the M1 card module 1 and the CPU card used by the CPU card module 2 are stored in the IC card data, the IC card also includes:

[0059] The first update unit 3 is used to update the CPU card data according to the M1 card data before using the CPU card module 2 to perform the IC card transaction operation;

[0060] The second update unit 4 is used for updating the M1 card data and the CPU card data during the IC card transaction operation with the CPU card module 2 .

[0061] Because there is a second update unit in the IC card of the embodiment of the present invention, this second update unit can update M1 card data and CPU card data when carrying out IC card transaction operation with CPU card module, therefore when carrying out any IC card with M1 card module During the card transaction operation, the M1 card data must...

Abstract

The invention provides an integrated circuit (IC) card and a data updating method thereof, belonging to the technical field of IC cards and capable of solving the problem that the synchronism of M1 card data and central processing unit (CPU) card data can be realized only when M1 card read-write equipment is updated in the conventional IC card. In the IC card data updating method, the IC card comprises an M1 card module and a CPU card module, and M1 card data used by the M1 card module and CPU card data used by the CPU card module are stored in the IC card. The method comprises the following steps that the M1 card data is used to update the CPU card data if the CPU card data is inconsistent with the M1 card data before the IC card module performs IC card transaction; and the CPU card module is used for performing IC card transaction, and the CPU card data and the M1 card data are updated in the IC card transaction. The IC card comprises the modules or units used for realizing the functions. The invention can be used in an IC card with both a CPU card module and an M1 card module.

Description

technical field [0001] The invention relates to the technical field of IC cards, in particular to an IC card with both a CPU card module and an M1 card module and a data updating method thereof. Background technique [0002] IC cards (integrated circuit cards) are widely used in fields such as fee payment (such as bus cards), identity authentication, attendance statistics, and card swiping records. Among IC cards, M1 cards (Mifare One) using logic circuits and CPU cards with microprocessors are two important types. Many existing IC cards have both M1 card module and CPU card module, so it can use M1 card module for IC card transaction operation, and CPU card module can also be used for IC card transaction operation, or it can be used for M1 card The read-write device can also be used for the CPU card read-write device, thereby having a wide application range and being convenient for users. This kind of IC card can be equipped with a microprocessor and a logic circuit at th...
