But because its near field (general 5~10cm) communicates the characteristics of reading and writing, even if its (such as identity card no longer valid in systems Expired or holder is dead), report the loss (loss of such as identity card), early warning (holder of such as identity card is pursued and captured an escaped prisoner), card card itself Also still it can not can be illegally used or be falsely used by remote read-write, label or cancellation；The verifying device of non-contact IC card, generally Only there are or only opened information read functions, even if failure may be recognized when networking and verifying with background data base or hung It loses or the card of the abnormalities such as early warning is demonstrate,proved, also it can not be marked or is nullified, card card can still be demonstrate,proved by illegal use repeatedly to card Loss person causes greatly puzzlement, loss and the wasting of resources with card unit, public security, judicial department.

In existing technical solution, patent document, finds no effect and solve the above problems method.For example, some schemes It is to assign unique coding to each card card with area with the issuing date of planned network searching platform inquirying card card, the scheme having Card card point made up etc., but report the loss, fail, early warning card card still can not be labeled or nullify itself, still can by again, it is repeatedly non- Method uses, and there are also the difficulties such as verification, management.

In view of in contactless IC card system, the more new information of background data base storage (accreditation history, hang by such as routine information Forget record, log-out etc.) it authorization reading, reader technology can quite be popularized in networking；And Wireless/wired network is wide General covering, make verify device can exchange information with background data base in real time in most cases, meet state's laws provide, In the case of protecting individual privacy, this is solved the problems, such as with straightforward procedure.

Summary of the invention

The present invention provide a kind of contactless IC card and can significant notation, identification and the method for cancellation, including card card, verifying dress It sets and background data base；This method is suitable for including but is not limited to that ID card demonstrate,proves (such as resident identification card, E-Passport, motor vehicle Driving license, personnel/animal/article identification card card etc.), qualification card card (such as driver's license, licensing, warrant, merit card Deng), password card card (such as access card), function card card (such as campus card, member card, fiscard) including non-contact IC Card.

The present invention is that the technical solution solved the problems, such as is: the setting write-in number limitation in the memory of contactless IC card Area, and store represent the card card or once in background data base status information status code；Verifying device can be read, simultaneously The status code in card card can be rewritten under setting rule；It is saved in background data base newest with the corresponding card holder of card card Status information.When card card networking verifying, status code is verified device reading, and can be with the current state information pair in database Than being marked as status code memory block in abnormal or card card and having had reached to allow to be written if the two is consistent or blocks status code in card Maximum number of times can then prompt verifier, conversely, then rewriting the status code by pre-defined rule automatically, and can prompt verifier.

Write-in number limitation in status code memory block in setting card card, it is mainly non-to avoid having been labeled as abnormal card card Authorization reverts to normal；The upper limit that number limitation is written depending on the requirement to card card security level and establishes write-in number limit The type of skill in area processed, general to may be selected to set the upper limit be primary, such as resident identification card, driver's license, identification card, gate inhibition Card etc..Any state in the database is abnormal card card, as long as the verifying device being networked for the first time is read, state, that is, quilt Automatic identification simultaneously marks, and the verifying device of later any local verification or networking verifying can recognize and can prompt verifier, should Card card can not be verified again；It represents card and demonstrate,proves normal or abnormal status code and display character, it can be customized in advance.

The invention has the advantages that effectively realize to fail, report the loss, the contactless IC cards of the abnormalities such as early warning Label, identification or nullify, solve report the loss, fail contactless IC card card it is illegal using to card demonstrate,prove loss person, with demonstrate,prove unit, Caused by public security department, judicial department etc. puzzlement and potential loss, and to early warning card card intercept timeliness the problems such as；It solves The problem of intercepting timeliness is demonstrate,proved to by early warning card.

Specific embodiment

The following examples are exemplary, for explaining only the invention, and should not be understood as whole embodiments or right Limitation of the invention；Every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.

Implementation of the invention, including contactless IC card, background data base, verifying device three parts:

One, definition represents the status code of card card status information, in order to show and recognize, corresponding memory actual storage two into Code processed.Such as with character N representative, normal, X represents exception, R representative is reported the loss, C represents cancellation, 0/1/2/3... respectively represents head Secondary accreditation/second of accreditation/third time accreditation ... accreditation version etc.；Certainly, binary code also can be used directly.

Two, write-in number restricted area and status code are established in contactless IC card:

With physics or software mode, write-in number restricted area is established in the storage chip of card card, setting can be verified device and write The maximum number of times entered, write-in card demonstrate,prove initial information when accreditation.

Physics mode: card card when manufacturing and designing, the corresponding write-in number restricted area of memory partially or fully, use The manufacture of disposable programmable read-only memory technique, such as PROM, OTPROM type.Manufacturing process determines that number is written in the region The upper limit is 1, i.e., only writable primary；Initial information when the corresponding code of storage state is contactless IC card accreditation when factory State code.

Software mode: for card card when manufacturing and designing, memory can be using repeatedly write-in type memory, such as EEROM (electronically written electrically erasable read-only memory), EPROM(electronically written ultraviolet erasing memory) etc., but manufacture or accreditation are demonstrate,proved in card When, certain memory space is distributed as write-in number restricted area, storing initial status code, and presets the area with program counter Domain allows the maximum number of times being written, and every write-in is primary, and counter adds 1 automatically, after reaching the maximum number of times for allowing to be written, automatically Forbid the write-in to the region.

Three, background data base establishes status information:

Representative card card status code corresponding with the card above-mentioned status code of card or status information are established in background data base.

Four, device is verified:

With read/write function, status code in readable card taking card, can when networking verifying by the status code with it is current in database Status information comparison, the two be consistent or block status code in card be marked as abnormal or card demonstrate,prove in status code memory block have reached Allow that maximum number of times is written, verifier's verification result can be prompted, but forbids rewriting status code in card card automatically；Conversely, then automatic The status code is rewritten by pre-defined rule and is the status code of representative exception, and can prompt verifier.

Original verifying device reuses: for having had the verifying device of read/write function, software upgrading makes to have above-mentioned Function.For not having the verifying device of write-in functions, software and hardware upgrading keeps it writable on the basis of original function, has Above-mentioned function；Or only software upgrading, make above-mentioned status code in its readable card taking card, prompts verifier, in this case, this is tested Though card card cannot be written in card device, have authentication function, can recognize marked card card.
