.SH DESCRIPTION
|
|
.B nfc-mfclassic
|
|
is a MIFARE Classic tool that allow to read or write

.IR DUMP
|
|
file using Mifare keys provided in
|
|
.IR KEYS
|
|
file.
|
|
|
|
MIFARE Classic tag is one of the most widely used RFID tags.
|
|
|
|
The firmware in the NFC controller supports authenticating, reading and writing
|
|
to/from Mifare Classic tags. This tool demonstrates the speed of this library
|
|
and its ease-of-use. It's possible to read and write the complete content of a
|
|
Mifare Classic 4KB tag within 1 second. It uses a binary Mifare Dump file (MFD)
|
|
to store the keys and data for all sectors.
|
|
|
|
Be cautious that some parts of a Mifare Classic memory are used for r/w access
|
|
of the rest of the memory, so please read the tag documentation before experimenting too much!
|
|
|
|
The 'u' option allows writing of special Mifare cards that can be 'unlocked' to allow block 0
|
|
to be overwritten. This includes UID and manufacturer data. Take care when amending UIDs to set
|
|
the correct BCC (UID checksum). Currently only 4 byte UIDs are supported.
