Proxmark being weird

Aha, I know you had a 4 byte UID, HF.

But yep, that also ties in with an xMagic.

I thought you said xM1 at some stage…

Anyway, yep strange you can’t see LF.

The PM3 can be tricky to read LF sometimes.

Press the antenna firmly perpendicularly across the xMagic (with some playing, you’ll be able to work out which end is LF and which is HF)

Use these to help
