Table 6 : Mifare Ultralight Memory Map
Example:
1. To authenticate the Block 0x04h with a {TYPE A, key number 0x00h }. For PC/SC V2.01,
Obsolete.
APDU = {
FF 88 00 04 60 00h };
2. To authenticate the Block 0x04h with a {TYPE A, key number 0x00h }. For PC/SC V2.07
alaAPDU = { FF 86 00 00 05 01 00 04 60 00h }
Note: Mifare Ultralight does not need to do any authentication. The memory is free to access.
