Hi every one
I am using a PCD (proximity coupling device or the card reader) like CLRC663 for reading RFID tags too. connection between PCD and MCU is based on SPI,Becouse of unsecure and un-encrypted connection between them ,each attacker can sniff the connection and achieve the keys used for reading and writing to the RFID tags. what is your suggestion for this?
