Working on Win XP SP3 and MacOSX:

Getting the revision R62, executing the win 32 binary from old-bin directory, works fine.
Compiling mfcuk using libnfc-1.5.1 dones not get any keys, on Win32 and MacOSX.

Anyone share the same experience ?

Regards,

Thomas Hood made a PPA for libnfc and mfoc:

Ubuntu Natty users could use it to ease installation and maintenance.

So here's my plan..
A Mifire card ( classic ? i read that the security of this is already cracked....bt just for demo i can use it right?
A PN532 breakout board

And next i'd like the card to be read by a PC which i presume can be done connecting the breakout board with a FDTI cable and ...Am I right that THIS is where i need libnfc library ( is it not a sort of driver for NFC chips...) and write my own part of the code that maintains database about student library info and all..
Oh yes !! i should also be able to write the data to card about the book issued and due date etc..i am certain that's not too difficult once acceced with a computer...

But along with this i'd also like to use it on standalone environment..say as attendance where the microcontroller simply displays ( or records ) the name and roll number of student..where unlike in library there is no need of a PC...I've come to understand that it can also be done by connecting to my favourite microcontroller via UART with the PN532 breakout board.
Now how do i program it for standalone environment ?? Can i use libnfc then??

I know that i might be seriously wrong on some issues..please donot hesitate to use any rough language if you feel the need to. And i know it'd be better if i bought all those and start playing around with it...then the questions would be relavant...but i live in nepal and i have to go through a painful process to get the card and the breakout board..and i cant afford to buy it if the project i am planning is way out of my range..or simply not possible..
So please answer as much as you can...with any other things i need to know.that i might have completely forgotten to ask..

Most imporatantly can such project be done..reading from PC ( i guess that's the easy part right?) and microcontroller on a standalone environment..simultaneously..from a single card...

forgive my weird abbv. of computer as PC....and anything else that might have bothered you
Thanks a lot in advance !!!

This way you can relay (even a contact based) smart card in  a smart card reader that only comes with a proprietary driver via NFC. But you could also use a software emulated smart card to connect to a real contactless smart card reader. Such a virtual smart card is also provided by the Virtual Smart Card Architecture. An other possibility is to relay a smart card between two computers and still appear valid in front of a certified contactless smart card reader. The latter has been demonstrated with the new German identity card, neuer Personalausweis (nPA).

I would like to introduce you the pinKey SDK project. This project, lead by Card Tech srl, aims to provide an Open Source platform over which to develop rich NFC-capable applications. Obviously the main building blocks of our NFC software stack are libnfc (1.4.2), libfreefare (0.3.1) and libndef (1.1.1) libraries.

I think it represents one of the firsts projects having reached a significant maturity stage, allowing for the developer to build custom NFC-oriented applications.

The provided application environment is based on Qt Framework and Qt Quick technology (http://qt.nokia.com). Currently it takes advantages on Qt 4.6 with the upgrade to the more powerful Qt 4.7 release with full Qt Quick and Qt Mobility support already scheduled for the near future.

At the moment we have developed a system service that handles NFC target discovery and recognition of Mifare Ultralight and Classic tags, providing an easy-to-use API that includes Read & Write functionalities of both raw an NDEF messages compliant to the NFC Forum standards (NDEF, TLV, etc. specifications).

This system service is integrated into a complete embedded operative system, called ODIN OS (http://developers.card-tech.it/odin-os), delivering biometric identification through a fingerprint recognition technology.

This particular platform can thus be used to build applications specifically conceived for security driven services, such as micro-payments, access control and secure data management.

To demonstrate the platform suitability to this particular application range, we've also developed several demos and examples, based on these services, that are included in the SDK (e.g. vcard exchange, simulation of NFC-based micro-payment, personnel identification with both NFC and biometric readings, password management, etc.).

The reference hardware, an in-house development device called pinKey Touch, features NXP's PN532 chip with the option for a P5CN072 SAM (Security Access Module) connection.

The pinKey SDK will be soon available for free download from the Card Tech Developers community website at the following address:

http://developers.card-tech.it/download

On the same website you can find more informations about pinKey SDK and pinKey Touch reference device.

I am pretty new to NFC and I am experiencing an issue while trying to use some of the applications provided by libnfc.
I have a PN532 NFC/RFID controller breakout board as reader and I use a Philips MIFARE card (provided with the board). The board is connected to a Linux environment by means of an uart connection.

I would like some help about 2 things.

I have successfully installed the libnfc (with the parameters --with-drivers=pn532_uart – enable-serial-autoprobe)

When I realize a “nfc-anticol”, I obtain this :

$ nfc-anticol 
Connected to NFC reader: PN532 (/dev/ttyS0) - PN532 v1.6 (0x07)

Sent bits:     26 (7 bits)
Received bits: 04  00  
Sent bits:     93  20  
Received bits: 3e  65  4b  9a  8a  
Sent bits:     93  70  3e  65  4b  9a  8a  e9  7b  
Received bits: 08  b6  dd  
Sent bits:     50  00  57  cd  

Found tag with
 UID: 3e654b9a
ATQA: 0004
 SAK: 08
 

The card seems to be correctly found.

(I have also installed “nfcutils” and with a “lsnfc”, I obtain :

$ lsnfc 
device = PN532 (/dev/ttyS0) - PN532 v1.6 (0x07)
UID=3e654b9a
Several possible matches:
* NXP MIFARE Classic 1k
* NXP MIFARE Plus 1k
1 tag(s) on device.

)

The problem appears when I use “nfc-list” and “nfc-poll”.
With nfc-list, the device is found but there is an “infinite loop” and I don't think it is correct according to the nfc-list example in the libnfc documentation.

$ nfc-list 
nfc-list use libnfc 1.4.2 (r891)
Connected to NFC device: PN532 (/dev/ttyS0) - PN532 v1.6 (0x07)
1 ISO14443A passive target(s) was found:
    ATQA (SENS_RES): 00  04  
       UID (NFCID1): 3e  65  4b  9a  
      SAK (SEL_RES): 08  


(and nothing else...)

I have the same result with “nfc-poll” :

$ nfc-poll 
nfc-poll use libnfc 1.4.2 (r891)
Connected to NFC reader: PN532 (/dev/ttyS0) - PN532 v1.6 (0x07)
PN532 will poll during 30000 ms

(and nothing else...)

Is there someone having experienced such issue?

PS: When I realize a nfc-list with debug enabled, I obtain the same result with more lines of DBG. But about some seconds, there is only an “infinite” line displayed:

nfc-list: DBG uart_posix.c:219
nfc-list:     iExpectedByteCount == 0

So I think the infinite loop is due to this iExpectedByteCount... I tried to see the uart_posix.c file but I don't really see how to solve the problem.

My second question is regarding reading / writing data from / to the card.
I use the “nfc-mfclassic r a test.mfd” tool to read the data from the card and I obtain the file which looks like the example file: http://www.libnfc.org/_detail/libnfc/do … mfclassic.

I would like to know what means the “a” or “b” key in the command line? And do you know what are the “key blocks” in the file?

Sorry for all these questions and thank you very much for any help !

To see current features and supports, go to libfreefare's wiki page:
http://code.google.com/p/nfc-tools/wiki/libfreefare

https://sourceforge.net/projects/ifdnfc/

This tool allow to recover one or more keys from Mifare Classic very quickly (few minutes) if at least one key is known.

Thanks to Norbert Szetei and Pavol Luptak for their attack's implementation.
Thanks to Michal Boska for making this works with libnfc 1.3.3.

http://code.google.com/p/nfc-tools/wiki/mfoc

Renamed MFCUK for MiFare Classic Universal toolKit, this project based on libnfc provide a simply command line to recove whole keys of a Mifare Classic in few minutes.

http://code.google.com/p/mfcuk

Now, this project is looking for contributors to bring MFCUK works with libnfc 1.3.9, I already did some works be applying API changes to MFCUK but I can't get it works with the lastest libnfc. If somebody have some knowledge in Mifare Classic hacking and wants to improve this tool, please contact me or Andrei Costin to gain an SVN access to MFCUK project.

lsnfc is a part from nfcutils package in nfc-tools project (http://code.google.com/p/nfc-tools/).
As a part of nfc-tools, nfcutils is under GPL license and contributions are welcome.

My idea is to use a cheap reader like the Touchatag and either something like the marvell power plug computers or just a router with a usb port. Then when someone enters the house they can just put their tag on the reader and it will instantly send the wake up on lan command to the right computer.

How much power it would actually save, I'm not honestly sure. I already have the parts (Touchatag reader + ASUS Wl500g running DD-WRT) so it's just a case of software.

From what I can tell all I need to do is:

- Compile LibNFC for ARM
- Create a Daemon to do the job

So, what do people think? genius or dumbest idea ever?

The reason for this posting is that this application uses libnfc ( version 1.2 at the moment ) to provide cross-platform (win32/win64,Linux and MacOSX) driver support for talking to the Snapper Feeder (NXP PN531).

In terms of layering, we have an Adobe AIR application talking to a native application compiled with a static copy of libnfc-1.2 supporting only the Snapper Feeder.

On Windows 32bit and 64bit platforms this uses a signed installation of libusb-win32 that provides driver bindings for the PN531.

We will be posting the source to the binary application shortly.

Just to let you know that I've started a project called pynfc, designed to offer python bindings for the libnfc code.  They currently offer good support transceiving both bits and bytes in an intuitive fashion as both initiator and responder.  It comes with a small amount of example code that will offer a Mifare read request for a block, and verify the that the returned tag nonce is as expected.

It currently doesn't offer the full support that libnfc does, most notably it works primarily with 14443A tags only (although adding support for other card types shouldn't be difficult, I don't really have any others to test out).  It also currently won't allow choosing which reader to read from, since that was all added in libnfc-1.3.3 and I haven't had time to catch up on it.  5:)

Requirements:
>= python-2.6
>= libnfc-1.3.1

Website & Bug tracker:
http://pynfc.googlecode.com/

If you'd like to help work on the code, or have any problems with it, do feel free to get in touch with me (or file a bug report).  Hope it's of some use...

This library affords the simultaneously connection of multiple readers, and up to three tags on each one (due to performance issues of the tags themselves on the touchatag reader). This project was tested on Windows 7 Professional and Windows XP SP3, with Processing 1.0.9.

You can download it here. For this library to work, users only need to install the Windows CCID PCSC driver, the touchatag software client isn't necessary. For more information head to the library's page on Google code.

Example:

import touchatag.*;
Touchatag rfid;

// Defines the maximum number of touchatag
// readers that might be connected to the computer 
int numOfReaders = 3;

// This library affords up to three touchatag
// tags on each of the touchatag readers
String[][] tags = new String[numOfReaders][3];

void setup() {
  // Optionally, if only one touchatag reader will
  // be used: rfid = new Touchatag(this) 
  rfid = new Touchatag(this, numOfReaders);
}

void draw() {
  // Gets the number of touchatag readers connected
  int readers = rfid.On();
  
  if (readers != 0) {
     // Gets the tags for each of the touchatag readers
     for (int i = 0; i < readers; i++) {
     tags[i] = rfid.tagsOnReader(i);
     println(tags[i]);
     }  
   }
}
