NFC RFID CUID Gen2 Magic 13.56MHz MF Classic 1K for Android MCT Proxmark3

Description

UID-changeable Gen2 Magic RFID/NFC card for MCT app, Proxmark3, access control, pentesting, etc.
This is a Gen2 Magic card, block 0 is not protected and can be rewritten with standard tools, including the popular Android MCT app.
!! WARNING !! Writing invalid data to block 0 can brick the card in ways that are difficult or impossible to recover.  You must correctly calculate the check values before
writing the block!  MCT does this automatically with its Clone UID tool.
The main photo is sort of boring, see the other photos for screenshots of the card in action.  Trademarks have been masked in the photos because certain companies have nothing better to do than trawl eBay for opportunities to file infringement claims.
Hard glossy plastic, non-printable.
