.SH NAME
|
||||
nfc-jewel \- Jewel command line tool
|
||||
.SH SYNOPSIS
|

|
||||
.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)
