This is a true Gen4 Magic card, commonly known as "USCUID" or "GDMIC". It is NOT the "Gen4 Ultimate Magic Card".
Features:
13.56 MHz
Emulates both 4- and 7- byte UID cards of the Classic variety put out by a notoriously litigious Dutch company which likes to file eBay takedowns for naming their brands.
Supports "Gen1a" Chinese Magic mode (not activated by default)
Supports "Alternate Gen1a/GDM" mode (20/23 wUPC1 instead of 40/43)
Supports "Gen2" / "CUID" mode, unrestricted write access to block 0 (also not activated by default)
Supports EV1 Signature Emulation (also also... you get it)
Supports "FUID" mode, where block 0 can be written once using the Gen2/CUID protocol and is locked afterward
Supports "Shadow" mode, where normal writes will be accepted and will read back as written, but will revert to your
preset values after a few seconds.
Please note: you need a Proxmark, Chameleon or similar specialized tool to fully utilize this!
