.SH NAME
nfc-jewel \- Jewel command line tool
.SH SYNOPSIS
.B nfc-jewel
.RI \fR\fBr\fR|\fBw\fR
.IR DUMP
.SH DESCRIPTION
.B nfc-jewel
is a Jewel tool that allows one to read or write
a tag data to/from a
.IR DUMP
file.
Jewel tag by Broadcom, previously Innovision, uses a binary Dump file to store data for all sectors.
Be cautious that some parts of a Jewel memory can be written only once
and some parts are used as lock bits, so please read the tag documentation
before experimenting too much!
.SH OPTIONS
.BR r " | " w
Perform read from (
.B r
) or write to (
.B w
) card.
.TP
.IR DUMP
JeWel Dump (JWD) used to write (card to JWD) or (JWD to card)
.SH BUGS
Please report any bugs on the
.B libnfc
issue tracker at:
.br
.BR http://code.google.com/p/libnfc/issues
.SH LICENCE
.B libnfc
is licensed under the GNU Lesser General Public License (LGPL), version 3.

.B libnfc-utils
