Help with PDOL challenge

[merdeux50]

I noticed a crucial thing missing from your wiki which solved most of my issues.

I was using the Adafruit PN532 library, I changed it to salm pn532 library and it works better now.

If you got the pdol from the acr122 means that you got the track 2 as well.

Just add the track 2 to the token variable. There is an example in the code such as

char token[19] = {0x44,0x12,0x34,0x15,0x01,0x12,0x03,0x12,0xd2,0x41,0x12,0x01,0x10,0x12,0x09,0x99,0x99,0x99,0x1f};

and then emulate it.

Thank you for your reply, yes I can use it. But what’s the point in having bought the nfc copy cat with the ability to extract it through the pn 352 if I have to use another device?

How can I successfully use the copy cat?

Is there a pdf or document that explains the process?

[salmg]

The PDOL function was designed to challenge the card, to be able to extract track 2, NFC Copy Cat has to send the correct challenge at least in format to the card. That is what PDOL does. Basically it generates the "GET PROCESSING OPTIONS" command in format, so the card can answer with the track 2

Really you do not have to edit the code to work; this code is ready to use, if you press a button and it will spoof data, if you press the second one, it will try yo read the card automatically.

Thank you!

I will read all I can to understand the communication with the card.
It seems after trying the CheckPDOL I get (This card is not active btw...)

I’ve compared with cardpeek, the commands sent are the same. Copy cat gets error responses for some reason.

[merdeux50]

Any insight regarding the pdol check?

[merdeux50]

After reading most of the documents I found. I’m realizing that the script is fine.
For some reason the cards responses to the APDU and visa is too short for it to get the normal pdol.

There is a communication error somewhere.

The PN532 board is unreliable, it recognizes the board 1 out of 30 times.

Honestly guy, this is supposed to be for students and people that want to learn?
I’ve had an extremely uninterested and lazy response from all of you guys here. Giving me lazy responses.

Just take the money and run type of mentality. Pay 120$ with shipping for a 3$ elechouse pn532 and a MagSpoof that doesn’t work.

I’m disappointed

Hi @merdeux50 im really sorry about the timming on answering your issue, i must say our technical team is quite small and we're now focused on a new product, The Hunter Cat NFC we have noticed on the past the problem with the PN532 board sometimes it works in a bad way, talking in other topic, the maspoof should work as thats something that we always test on our product line
