9.2.5 MIFARE Classic
The MIFARE Classic example is implementing basic read/write functionality using a
MIFARE Classic card with a predefined default key. If a Type A card is detected with
SAK of 0x8 (1K MIFARE Classic card) or 0x18 (4K MIFARE Classic card), then the
MIFARE Classic example is executed. The example performs initial authentication of
block X and then reads/write to this sector. Further the example performs authentication
of another block (say X +1) using the session key established during initial authentication
(this is called re-authentication). It then performs read/write to this block X+1. See the
function
phExMain_MiFareClassic() and phExMain_MifareOperations()
Supported Functionality:
1. Authentication & Re-Authentication
2. Read/Write
Implementation in the “phExMain_MiFareClassic.c” file.
