Remark: The minimum required time between MIFARE Classic Authentication part 1
and part 2 is the minimum required FDT according to Ref. 4. There is no maximum time
specified.
Remark: The MIFARE Classic authentication and encryption requires an NFC reader
IC for MIFARE products (e.g. the CL RC632). For more details about the authentication
command refer to the corresponding data sheet (e.g. Ref. 5). The 4-byte input parameter
for the MIFARE Classic Authentication is detailed in Section 10.1.3 and Section 10.2.2.
12.2 MIFARE Read
The MIFARE Read requires a block address, and returns the 16 bytes of one MIFARE
Classic block. The command structure is shown in Figure 17 and Table 22.
Table 23 shows the required timing.
