First, Legic sensor card technical parameters 1, non-contact smart card technical parameters 1.1 Size: 54mmX86mmX0.75mm 1.2 Capacity: 22 Byte 256 Byte 1k Byte 8k Byte 1.3 Read and write time: read operation 5ms / Byte read operation 2.5ms / Byte write operation 20ms/Byte Write operation 5ms/Byte 1.4 Material: PVC Engineering material ABS Engineering material 1.5 Life: 100,000 write operations, read data infinitely after reading data once, data can be saved for 10 years 1.6 Environment: Working temperature -20°c- ---70°c Storage temperature -30°c----80°c 1.7 Working frequency: 13.56MHZ 2. Non-contact smart card internal partition non-contact smart card is divided into two parts: system area (CDF) user area (ADF) System Area: Used by card manufacturers and system developers and card issuers. User area: used to store information about the cardholder. 2.1 System area structure: The system area contains a total of 9 bytes, the distribution of which is shown in Table 1: Byte number address Bit attribute 1 0 0---7 MCD 2---4 1.2.3 0---23 MSN 5 4 0---7 MCC 6---7 5,6 0---15 DCF 8 7 0---6 WRC/WRP 8 7 7 RD 9 8 0---7 SSC Description: (1)MCD(Manufacture Code.) 1 byte stores the value 00H-FFH, used for the patent holder's number, has been set at the factory and cannot be changed. (2) MSN (Manufacture Serial No.) 3 bytes Valid value: 224 = 16, 777, 215 (for each MCD), factory set, cannot be replaced. (3) MCC (Manufacture check character) 1 byte first 4 bytes checksum MCD MSN MSN MSN MCC (4) DCF (Decremental field) Two bytes, can only be decremented, used for patent authorization (5 WRP (Write protect) Byte8 Bit0---3 Wrc (Write Conelifion) Byte8 Bit4---6 WRP is used to protect those user areas can not be repeated write operations Wrc for the password area SSC ADF1 ADF2 Note: can only be written once, Cannot be changed (6) RD (Read Disable) Byte8 Bit7 RD=0 Any WRU can read RD=1 Only authorized WRC, the content of the password area determined by WRC can be solved corresponding to CHIPS password (7) SSC (System Supplier Code) 1 Byte Patent No. 00H---FFH 2. Authorization and Issuance of Legic Contactless Smart Cards Any non-contact smart card and reader without authorization from the card issuing center, cards and readers cannot jobs. Cards and readers provided by the product manufacturer must be authorized by a special authorization card held by a card-issuing center before they can be put into the market. LEGIC (modules are divided into: MSM authorization card generation, blank card authorization.) 1. SM user card reading and writing module card is divided into: GAM: General Authorization Media SAM: System Authorization Media IAM: Identification Authorization Media AM: Authorization Media IM :Identification Media NM:New Media 2. The order of authorization cards is shown in the following figure: GAM GAM SAM IAM GAM SAM IAM 3. User authorization module and user card authorization are as follows: SAM IAM MSM AM NM MSM SM IM
