1, the write-protected area (first 32 bytes) of each byte can be individually write protected, write protection, the content can not be changed (ie, curing data)

2, right before checking the password, all data can be read, if necessary, appropriate encryption of data into the ground.

3, after checking the password is correct to write or modify.
4, the three bytes of the user's password, check the correct itself after the change, the effective power to the card until the next.
