.TH nfc-mfsetuid 1 "Sep 05, 2011" "libnfc" "NFC Utilities"
.SH NAME
nfc-mfsetuid \- MIFARE 1K special card UID setting and recovery tool
.SH SYNOPSIS
.B nfc-mfsetuid
[
.I UID
]
.SH DESCRIPTION
.B 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'.
.SH OPTIONS
.B -f
Format. Wipe all data (set to 0xFF) and reset ACLs to defaults.
.B -q
Quiet. Suppress output of commands and responses.
.SH BUGS
Please report any bugs on the
.B libnfc
issue tracker at:
