Reading data from a transponder card:
The example below describes the sequence to read out the 12th sector of a Mifare transponder card with the
physical transponder address 0x9C 4B 23 D2.
This card is stored in the RFID field of the RFID read / write device. At the same time, another transponder
card is also located in the recognition field of the read / write device.
The card is assigned with the "transport configuration" status.
