Non-contact type Ic card production, contactless IC card production, card prepaid card production price

Contactless IC card Model: SLE4442 / SJE5542 / SLE4442 is a common ratio effect of contactless IC card chips, mainly used in the Internet cafe management, contactless IC card locks, membership points stored value contactless IC card meter, contact IC card meter, contactless IC card gas meter, its cost efficiency is low, stable performance, the Chinese market has been widely applied. First, the main indicators: 256 bytes EEPROM organization, composed of 32-bit protected mode memory, 3-byte user password, the password error count: 3 times, temperature range: 0 ℃ ~ 70 ℃, at least 100,000 times erase, at least 10 Two-year data retention, privacy features: 1. check the correct password before all the data can be read, if necessary, the data can be properly encrypted. After checking the correct password contactless IC card can write or modify data. 2. Three bytes of user passwords. After check-contact IC cartoon password itself can be changed. Note: Also addressing the password area, not within the 0 to 256 bytes. 3. The contactless IC card password error counter, the initial value of 3, check the error code 1, then subtract 1, if the counter is 0, the card is automatically locked, contactless IC card data can only be read, contactless IC the card can no longer change the password can no longer check; if not zero, the one time password verification is correct, restore to the initial value. 4. Each byte write contactless IC card protected area (first 32 bytes) can be individually write-protected, it is write-protected, contactless IC card content can not be changed (ie curing data). 5. byte address 0x15 ~ 0x1A for customer code, SIEMENS company for large users contactless IC card designed for a globally unique code, so users unified release using contactless IC card (all cards can not be modified after leaving the factory). 6. byte addresses 0 to 7 is factory-written by the manufacturer, can not be changed. Contactless IC card chip at the factory according to the specific requirements of the user programmable encryption codes (PSC) memory incorporated into a special code. So that when the contactless IC card, it must be legal to get this code to prevent unauthorized use of illegal or counterfeit cards.
