 06 May 2007 22:48 Mifare RFID reader help |
|
|
|
Hello,
I need to design an Mifare/ISO14443 RFID reader for the Mifare S50 cards. I use an MFRC53101 IC and ATmega8 microcontroller, connected to PC via RS232.
So far I wrote and tested the C code (on uC) for initializing the MFRC53101, reading and writing registers and FIFO buffer, and a few commands.
The question is how to read and write a new S50 card, in the simplest way, to test the commands. I must use authentification for every access to the card, and if so what keys to use for a blanc card? If you know a tutorial or an example program, it would be very helpful. It should be something very simple, just to test the capabilities of the card and reader. I've seen the open pcd program at www.openpcd.org ,and it seems too complex for a beginner.

As I remember it was all Fs in hex.
There is a good forum for RFID
http://www.rfid-handbook.com/forum/index.php
You can get more details about your RFID project
Hope this helps
It's my pleasure to keep in contact with you as I'll start in the same project after some period

Thanks for your reply.
So far I succeded to detect (unsing the REQA command), select and authentificate the card.
Now I need some help for writing and reading a sector.

This link and sources are useless. Source lacks the most imporant part of application: use of library. Documentation for mcf500 is really bad (close to none). I wonder how this guy managed to get circuit cellar award for incomplete project. Documentation for the project itself is not so great. It doesn't explain mifare at all!
Anyway, this board has several uploaded documents about mifare. All can be downloaded from nxp site so save your DL and BW. But none of those documents show the bare protocol information. The only useful document I found is Ultralight product specification:
http://www.nxp.com/acrobat_download/other/identification/M028634_MF0ICU1_Functional_Spec_V3.4.pdf
Some part of this document can be used for other Mifare Classic cards. This document has (partial) command set description including timing information. Now the question is why there is no such document for Mifare 1K or Mifare 4K.
