Description
Technical field
The present invention relates to the IC-card technical field, relate in particular to a kind of IC-card and data-updating method thereof that has CPU card module and M1 card module simultaneously.
Background technology
IC-card (integrated circuit card) is widely used in the fields such as reimbursement of expense (as mass transit card), authentication, work attendance statistics, the record of swiping the card.In IC-card, the CPU card that uses the M1 card (Mifare One) of logical circuit and have a microprocessor is two kinds of important type.Have M1 card module and CPU card module in existing many IC-cards concurrently, so being available M1 card module, it carries out IC-card transaction operation, also available CPU card module carries out IC-card transaction operation, it can be used for M1 card read-write equipment in other words, can be used for CPU card read-write equipment again, thereby the scope of application is wider, can make things convenient for the user.Can have microprocessor and logical circuit simultaneously in this IC-card, also can simulate the M1 card module by the CPU card module.
Because the M1 card module is different with the desired data layout of CPU card module, therefore must store respectively M1 card data and CPU card data (these two groups of data can be stored on the different memory, also can be arranged in the different memory areas of same storer) in the IC-card simultaneously for M1 card module and the use of CPU card module.These two groups of data can comprise surplus capital amount (to having the IC-card of electronic purse function), residue swipe the card number of times (to having the IC-card of metering function), residue integration, card number etc. respectively, and its value can be operated (for example consume operations, supplement operation, card number alter operation etc. with money) along with the IC-card transaction and be changed (when for example consuming surplus capital amount can reduce etc.).
Obviously, in the IC-card, M1 card data and CPU card data should be consistent (are surplus capital amount, the residue of the two representative swipe the card number of times etc. should be identical), in order to avoid the user feels wherein to have two different card modules.But, because M1 card data, CPU card data are separate and be used for different card modules; Therefore, when carrying out IC-card transaction behaviour with a kind of card module wherein, have only and to change according to operating result data that should card module, the data of corresponding another card module then remain unchanged, this just causes M1 card data and CPU card data inconsistent (for example also remain 10 yuan of funds in the M1 card data representation IC-card, and also remain 8 yuan of funds in the CPU card data representation IC-card).For avoiding the nonsynchronous phenomenon of this data to cause problems such as charging confusion, the data-updating method of existing IC-card is as follows:
IC-card transaction operation (as consume operations, supplement operation, query manipulation with money) is preceding carrying out with the M1 card module, if the recent renewal of CPU card data is later than the recent renewal (being that CPU card data are newer) of M1 card data, then, make M1 card data and CPU card data sync with CPU card Data Update M1 card data;
IC-card transaction operation (as consume operations, supplement operation, query manipulation with money) is preceding carrying out with the CPU card module, if the recent renewal of M1 card data is later than the recent renewal (being that M1 card data are newer) of CPU card data, then, make CPU card data representation and M1 card data sync with M1 card Data Update CPU card data.
In the said method, M1 card data and CPU card data all can be synchronous when each user swiped the card operation, thereby made the existence of imperceptible two card modules of user.Wherein, which newly can be judged by new logo is set in one group of data more in two groups of data: when carry out IC-card transaction operation with a certain card module after, delete original more new logo, and add more new logo in the data of this card module; So just can guarantee always to have more new logo in the data of recent renewal.
The inventor finds that there are the following problems at least in the prior art: the M1 card is a logic encryption card, relies on logical circuit to carry out computing, so the sequential of its computing is very strict, can't change easily; And in the prior art, carry out IC-card transaction operation with the M1 card module before, to carry out Data Update, this can change its original work schedule, causes transaction normally to carry out, and could realize above-mentioned IC-card data-updating method so must upgrade or change existing M1 card read-write equipment.

Carry out IC-card transaction operation with described CPU card module, and in described IC-card transaction operation, upgrade described CPU card data and M1 card data.
Because in the IC-card data-updating method of the embodiment of the invention, CPU card data and M1 card data when carrying out IC-card transaction operation with the CPU card module, have been upgraded simultaneously, therefore must be consistent carry out IC-card transaction operation back CPU card data with the CPU card module with M1 card data, like this when carrying out any IC-card transaction operation with the M1 card module, M1 card data must not can lag behind CPU card data, just do not need to upgrade M1 card data yet, so it can not cause the variation of M1 card module sequential, need not upgrade M1 card read-write equipment yet.
Embodiment one
The embodiment of the invention provides a kind of IC-card data-updating method, has CPU card module and M1 card module in this IC-card; And store M1 card data of using for the M1 card module and the CPU card data of using for the CPU card module in the IC-card respectively.
Preferably, M1 card data and CPU card data are any data that relate in the process of exchange, as comprise swipe the card at least a in number of times, the card number of surplus capital amount, residue integration, residue.
Preferably, the form of described M1 card data is same as the prior art, comprises the secondary data of M1 card master data and M1 card, and these two groups of data are consistent, thereby backup each other; In M1 card master data and the secondary data of M1 card, also can be respectively equipped with the proof test value (this proof test value can calculate by data itself) that is used to check data correctness.Why M1 card data preferably adopt two groups of data and have test value, are because the M1 card is a logic card, relatively are easy to generate mistake, and above-mentioned data layout can improve its reliability.Because this form of M1 card data is prior aries, so no longer be described in greater detail at this.
The IC-card data-updating method specifically comprises:
S01, user card punching power on card;
S02, judge whether this operation is (this judgement can be undertaken by the order that read write line sent) that carries out with the CPU card module; If then carry out next step; (if promptly operation is carried out with the M1 card module) if not, then directly carry out IC-card transaction operation with the M1 card module, and the operation of not carrying out with CPU card Data Update M1 card data is (certain, carry out IC-card transaction operation with the M1 card module before, also can comprise the correctness of M1 card data such as is checked at conventional steps).
S03, preferably checks the correctness of M1 card data.This checks that available existing method carries out, its process can be as shown in Figure 2, comprise: with the proof test value of M1 card master data and the secondary data of M1 card the correctness of two groups of data is checked respectively, if two groups of data all correctly then finish to check, if one group of wrong data of then using correct Data Update mistake of correct another group of data is if two groups of equal mistakes of data then report an error.Obviously, the concrete grammar of this inspection step can carry out many variations, and for example, it can check M1 card master data as shown in Figure 2 earlier, but also can check the secondary data of M1 card earlier.Because the data checking of M1 card is a prior art, so no longer be described in greater detail at this.
Obviously, this inspection step is not necessary, if the accuracy rate of M1 card data is higher, can save this step yet.
Whether S04, judgement CPU card data and M1 card data (be often referred to M1 card master data, but also can adopt the secondary data of M1 card, down together) are consistent; If it is inconsistent then with M1 card Data Update CPU card data; If unanimity then enters next step.
Perhaps, this step also can be: do not carry out above-mentioned judgement, and directly with M1 card Data Update CPU card data (no matter promptly whether CPU card data consistent with M1 card data, all carrying out the operation with M1 card Data Update CPU card data).
Because the purpose of this step is synchronous CPU card data and M1 card data (promptly guaranteeing two groups of data consistents), so it can be realized by above-mentioned two kinds of methods.Wherein, first method will be judged, upgrades operation but can save partial data; Second method need not be judged, but may carry out unnecessary renewal again under the situation of CPU card data and M1 card data consistent.These two kinds of methods can be selected voluntarily according to the expectation environment for use of IC-card, in a word, carry out getting final product with the operation of M1 card Data Update CPU card data when CPU card data and M1 card data are inconsistent.
S05, carry out IC-card transaction operation with the CPU card module, preferably, this IC-card transaction operation comprises: consume operations, supplement at least a in operation, the card number alter operation with money.In IC-card transaction operating process, also need result's (as surplus capital amount after the transaction) to upgrade CPU card data and M1 card data according to transaction, just make CPU card data and M1 card data sync.Wherein, the operation of upgrading M1 card data comprises to be upgraded M1 card master data and upgrades the secondary data of M1 card, and upgrade the concrete order of respectively organizing data (CPU card data, M1 card master data, the secondary data of M1 card) is arbitrarily, as long as final CPU card data and the M1 card data sync of guaranteeing.
S06, EO, the card outage.
Obviously, after the S05 step, the client may carry out IC-card transaction operation with the CPU card module once more under the situation that card does not cut off the power supply, this moment is as long as directly carry out the S05 step, and need not carry out the S04 step again, because this moment, CPU card data all must be consistent with M1 card data, need not upgrade again.
Obviously, as if what carry out with the CPU card module is the IC-card transaction operation (operation that for example queries the balance) that can not cause CPU card data and M1 card data to change, the operation that then can not carry out in the above-mentioned S05 step upgrading synchronously CPU card data and M1 card data in this operation (can reduce the number of times of Data Update like this, but need the decision operation type), also can carry out above-mentioned S05 step (do not need like this to judge, but can increase the unnecessary renewal of part) as usual.These two kinds of methods can be selected voluntarily according to the expectation environment for use of IC-card.
In the method for present embodiment, when carrying out IC-card transaction operation with the CPU card module, comprise the step of synchronous renewal CPU card data and M1 card data; Therefore when beginning to carry out any IC-card transaction and operate with the M1 card module, M1 card data all must not can lag behind CPU card data, be M1 card data only may with CPU card data sync or than CPU card data also new (once be operating as the IC-card transaction of carrying out with the M1 card module for example and operate, then M1 card data change and CPU card data do not change); So carry out IC-card transaction operation with the M1 card module before, do not need with CPU card Data Update M1 card data, just can not cause the variation of M1 card module sequential yet, need not upgrade existing M1 card read-write equipment.Simultaneously, though in the IC-card transaction operation of carrying out with the CPU card module, increased the more step of new data in the method for present embodiment, but because the operation method of CPU card module can be adjusted arbitrarily by software, sequential is not strong, so it can not exert an influence to the use of IC-card.
In addition, owing in the method for present embodiment, do not exist with CPU card Data Update M1 card data conditions, so wherein also above-mentioned more new logo can be set no longer, with further simplification computing.
