We are trying to build a system based on an RPi3 that will read and write NTAG213 RFID tags. We are currently using the PCSClite library to interface to the RFID tag using a Advanced Card Systems ACM1252U card reader. I think that I understand how to do a basic read and write to the NTAG213 using the READ_BINARY and WRITE_BINARY commands. But I don't understand how to go about sending an NTAG213 PWD_AUTH command to the card so that we can protect portions of the card from reading. Is there a way to directly send low level commands through the APDU interface to the NTAG213?
Any help anyone can give would be greatly appreciated.
