Grumpy_Mike:
The UID of these two cards is different!
I can't see your problem.
This uses a 7 byte UID.
I know the 7 byte UIDs are different but I haven’t had any luck with finding a code or writing a code that can scan for 7 Bytes the one I have scans the first 4 bytes and those are the same on all of my mini rfid tags. So when scanned they all show up as 88 04 08 7A (I have no idea where the 88 is coming from)
I thought if I wrote something specific to to the rfid I could use that to differentiate but if it’s easier to code something to just read the 7 byte UID instead... I’m all ears.
We usually use bigger rfid tags where this code works fine and have only run into this issue with the tiny rfids which we need to use in our current game.
