Confidentiality Features: 1. Each byte of the write protection area (the first 32 bytes) can be individually write-protected. After the write- protection, the content cannot be changed (ie, the data is solidified). 2. Before the password is verified correctly, all data can be read. If necessary, the data can be properly encrypted. 3. The password can be written or modified after checking that the password is correct. 4. The three-byte user password, which can be changed after verification, is valid until the card is powered off. 5. The initial value of the password error counter is 3. If the password is checked for one error, it will be decremented by 1. If the counter value is 0, the card will be automatically locked, and the data can only be read out, and cannot be changed or checked again. If it is not zero, once the password is checked correctly, it can be restored to the initial value. 6. Byte addresses 0-5 and 6-7 have been written by the manufacturer before leaving the factory and cannot be changed.
We manufacture a range of contactless smart cards which chips are from leading chips manufacturers including NXP, Infineon.HlD, Atmel and more.
These cards have an embedded antenna that enables interaction with the reader without
physical contact.
