4 Byte & 7 Byte DESFire with UID, SAK, ATQA, ATS Changeable Setting up UID: hf 14a raw -s -c -t 1000 cf00000000CD00 Example: hf 14a raw -s -c -t 1000 cf00000000CD0011223344556677 Modify UID to 11223344556677 =========================================================== Setting up ATS: hf 14a raw -s -c -t 1000 cf0000000034< Length > < ATS > The length is set to 0, indicating that ATS is not sent When SAK is 20, 28, be sure to set ATS, otherwise you can’t read the card. The last two digits of ATS are CRC, which cannot be counted into the length Example: hf 14a raw -s -c -t 1000 cf000000003406067577810280 Modify ATS to 060675781028002F0 =========================================================== Setting up ATQA and SAK: hf 14a raw -s -c -t 1000 cf0000000035 Example: hf 14a raw -s -c -t 1000 cf0000000035440028 Modify ATQA=00 44 SAK=28 *Note that ATQA is inverted on pm3
