Waived my card over my Arduino Powered SM130 RFID reader to see what it would say..
Student Card: Mifare 1K(2) : 2ADEXXXX
Barclay Card: Unknown Tag(FF) : 09A1XXXX
It’s compatible with the usual RFID standards to some degree, enough to give the same serial number every time, unlike my passport which randomises its ID each activation, but not surprisingly it doesn’t read on my basic reader, probably a more advanced one would get further..
