5.8.4 Example program
The program sequence below shows how the basic RFIDApi functions are applied based on a simple
example.
On the example of the transponder card families MIFARE, ICODE SLI and UHF, the aim is to demonstrate
how a family initialises, how various cards are detected in the RFID field and how individual cards are
selected. Finally, the content of the first block on the transponder card is read out. This command is an
example to be applied to all other basic commands (e.g. read out AFI etc.).
The ACD DeveloperPack offers among other features useful functions for RFID readers installed in ACD
devices.
