MIFARE 1K special card UID setting and recovery tool


nfc-mfsetuid [ UID ]


nfc-mfsetuid is a MIFARE tool that allows setting of UID on special versions (Chinese clones) of Mifare 1K cards. It will also recover damaged cards that have had invalid data written to block 0 (e.g. wrong BCC). Currently only 4 Byte UID is supported. Specify an eight hex character UID or leave blank for the default '01234567'.


Format. Wipe all data (set to 0xFF) and reset ACLs to defaults.
Quiet. Suppress output of commands and responses.
