Ability is substantially strengthened, swipe the card distance be improved significantly, the accuracy rate of data transfer is significantly improved.
The invention also discloses the card writing method of RFID card, its step is as follows：
1) EEPROM user's spaces are set to 8K bytes, the ROM program spaces are set to 64K bytes, and COS software is set to
56K bytes, operational order is instructed using 32 bit encryption operations, and operational order, Card Reader instruct and write card and instruct all bytes positions
Differ；
2) CPU card card reader is connected, connection is opened software, initialized；
3) before card is write, card data preparation is stored in txt documents；
4) data display in txt documents is stored on software；
5) card structure is set up, sequence number is set up in card；
6) every RFID card carries out mono-recordable card sequence after setting up card structure.
The basic operation instruction of RFID card of the present invention is as follows：
1) (APPLICATION BLOCK) order makes the application failure currently selected：As APPLICATION BLOCK
Order is successfully completed using after temporary locking, with the application of SELECT command selections temporary locking, by loopback conditional code " no
Support this function " (SW1SW2=' 6A81 ')；(card for T=0 with GET RESPONSE, it is necessary to be instructed by loopback FCI simultaneously
Fetch), after APPLICATION BLOCK orders complete application permanent locking, hereafter perform all orders, card is by loopback shape
State code " applying permanent locking " (SW1SW2=' 9303 ').
2) (APPLICATION UNBLOCK) order is used to recover current application：As APPLICATION UNBLOCK
The limitation to application command response that order is produced will be cancelled.
3) (CARD BLOCK) order makes all application permanent failures in card：After CARD BLOCK are successfully completed,
All subsequent commands are not all by loopback conditional code " 6A81 " (supporting this function), and do not perform any other operation.
4) (EXTERNAL AUTHENTICATION) order is used for secrecy mould in the application verification interface equipment in IC-card
The validity of block, so that interface equipment obtains certain mandate.Certification read transmission key (CTK) in the case of three kinds below：
When only registering MF, MF is not created；MF is created, but during without creating KEY files under MF；Create MF
Under KEY files, but without create master control key when；
Certification DF transmits key in the case of two kinds below：DF is created, but without KEY files under establishment DF；Wound
KEY files under DF have been built, but without establishment master control key.
5) (GET CHALLENGE) command request one is used for the random of safety-related process (such as safe packet)
Number.
6) (GET RESPONSE) when APDU can not be used existing agreement transmission, " GET RESPONSE " orders are provided
A kind of transmission method that APDU (or APDU part) is transmitted from card to interface equipment.
7) (INTERNAL AUTHENTICATION) order is there is provided the random number sent using interface equipment and itself
The association key of storage carries out the function of data discriminating：When relevant key is located at MF layers, the order can be whole for differentiating
Individual card；When relevant key is located at DF layers, the order can be for differentiating this DF.
8) (PIN CHANGE/UNBLOCK) order allows card issuer to unlock personal identification number and (that is, resets personal identification number to attempt
The value of counter is the maximum times of application settings), or the transmission of personal identification number in personal identification number, order is all changed using encryption
Mode.
9) all or part of data are read in (READ BINARY) order from transparent file：As order includes effective base
This document identifier, the file corresponding to it is to be arranged to current file, and the order is only operated to current file, only
In the case where meeting the authority of current file read operation, the order can be just performed.
10) record or one that some specify are read in (READ RECORD) order from the constituent instruments of interrecord structure
The data of record start part.
11) (SELECT) order selects MF, DF or EF in IC-card by filename or application identifier：The order
Current file is set, and after this order is performed, back to back all orders are all impliedly operated to file.It is special for one
The private file is set to current file by the selection of file (DF), and the file that hereafter can be included to it carries out further
Selection.After reset answer, master control file (MF) is defaulted as current file.
12) all or part of data of (UPDATE BINARY) order write-in or modification transparent file：Use condition：
Order includes effective constituent instruments identifier, and the file corresponding to it is to be arranged to current file.Order is only to currently selected
The file (i.e. current file) selected is operated.Only when meeting the safety requirements of write-in or modification current file, the order
It can just be performed.The security attribute of current file defines the mode of secret communication, and only security classification is not less than this mode
Communication mode order can just be received.
13) (UPDATE RECORD) order is with the data more fixed record of new record file middle finger provided in order
Content：Use condition：Order includes effective constituent instruments short identifier, and the file corresponding to it is to be arranged to current file,
Current record pointer is resetted simultaneously.The order is only operated to currently selected file, is only meeting modification currently
During the jurisdictions mandate of file, the order can be just performed.If the operational mode of current file defines the mode of secret communication,
The communication mode order for being then only not less than this mode with security classification can just be received.For linear structure file, work as finger
When fixed recording mechanism is not present, it can add and record by the order of recording mechanism.When being not present by record identifier access record, also should
It is considered as the constituent instruments of addition new record, fixed length or loop configuration, institute is true when record length used must be with creating in name
Fixed record length is consistent, and otherwise name will be rejected execution, and the order opposes that the file of interrecord structure is effective.
14) (VERIFY) order is used to examine the correctness of the personal identification number in order data domain or return to allow to continue
Attempt the number of times examined：Locked personal identification number is verified, no matter how result does not affect error Counter Value, and
PIN is locked, the operation that could perform after inspection PIN in need can not perform.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
