xM1 Plus UID - 4 or/and 7 byte?



Short question: Can the xM1 Plus implant also get a 7 byte UID? Or only a 4 byte UID?

Thx :slight_smile:


The xM1+ emulates an original Mifare S50 1k chip, which only came with 4 byte NUID.


Bought XM1+. Earlier It was 7 bytes in description on site (now I can only see it in source code of the page). Found out itโ€™s actually 4 right now - after implantation. With 4 bytes itโ€™s unusable for mine desired purpose :frowning:
