Can any one else scan there Samsung phones on HF card reader and come up with a ISO14443-A tag even with the power to the phone off? I went to move my phone and set it on my KBR1 and it scanned so I got to playing with it proxmark reads it as a ISO14443-A.
My Samsung s-20 scans as well with only a 10 digit UID that changes with each scan, but I cant seem to get the proxmark to detect and it wont scan if its off. Like my s-10 does.
I have been trying to find info online but you can imagine that search gets mucked down with “how to scan nfc with your phone results”
I am assuming it is just part of the Samsung pay, Google pay the phones are capable of but the scanning even when the phone is off is what peaked my interest.
