The distance between the write and read pointer can be obtained by reading the FIFOLevelReg register. When the microcontroller starts a command, the MFRC522 can, while the command is in progress, access the FIFO buffer according to that command. Only one FIFO buffer has been implemented which...

74 of 109 NXP Semiconductors MFRC522 Contactless Reader IC This command terminates automatically when the MIFARE® card is authenticated and the bit MFCrypto1On in the Status2Reg register is set to logic 1. This command does not terminate automatically when the card does not answer, therefore...

Each mifare card has 16 sectors with 4 blocks, but the last block, block #3, hold the security keys and the permission allocated for it!. Then Only block 0,1 and 2, on each sector, are good to store data. The block 3 is for reading and writing permission!
