NFC RFID CUID Magic MF Ultralight-C 7 Byte UID DES Security

Description

UID-changeable Gen2 Magic RFID/NFC card for MFUL++ app, Proxmark3, access control, pentesting, etc.
This is a Gen2 Magic card, the normally protected blocks are not and can be rewritten with standard tools.  OTP bits are also resettable.
!! 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!  Proxmark will do this for you, if using MFUL++ you need to exercise care.
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.
