.TH NFC-EMULATE-UID 1 "June 26, 2009"
|
|
.SH NAME
|
|
nfc-emulate-uid \- NFC target emulation command line tool based on libnfc
|
|
.SH SYNOPSIS
|
|
.B nfc-emulate-uid
|
|
.RI [ OPTIONS ]
|
|
.RI [ UID ]
|
|
.SH DESCRIPTION
|
|
.B nfc-emulate-uid
|
|
is an tag emulation tool that allow to choose tag UID. Tag emulation is one of
|
|
the main added features in NFC. To avoid abuse of existing systems,
|
|
manufacturers of the NFC controller intentionally did not support emulation of
|
|
fully customized UID. The nfc-emulate-uid tool demonstrates that this can still
|
|
be done using transmission of raw-frames, and the desired UID can be optionally
|
|
specified.
|
|
|
|
Fast communication is necessary to respond in time during the anti-collision
|
|
protocol. Using the ACR122 device gives many timing issues, "PN53x only" USB
|
|
devices also give some timing issues but an embedded microprocessor could be
|
|
fast enough to emulate a tag with any UID.
|
|
|
|
This makes it a serious thread for security systems that rely only on the
|
|
uniqueness of the UID.
|
|
|
|
.SH OPTIONS
|
|
.IR UID
|
|
8 hex digits format that represents desired UID (default is DEADBEAF).
