I have a card from the hotel last weekend, I wasn’t able to dedicate enough time to fiddle with it to see what it was and clone it to my imolsnt
… so I just kept it to decode later lol
Only thing I can tel so far is it doesn’t scan with TagInfo… so could be 125 or mifare classic as mine won’t pick those up
There’s also a PL1 on the bottom of the card if that bears any significance
