How to clone cards using RFID?

akatchi · December 5, 2016, 4:49pm

Hey guys,

So I got the RFID working, and I tried to duplicate a certain pass where I can acces my stuff with.
Now I tried to duplicate it with the 'RFID_Clone' sketch in the examples but it's not doing anything at all,
then I saw that you need to hard-code the card you want to duplicate but I have seriously no idea how..
Can someone help me?
Full sketch will be attached, part of the sketch where I'm stuck:

// Number of known default keys (hard-coded)
// NOTE: Synchronize the NR_KNOWN_KEYS define with the defaultKeys[] array
#define NR_KNOWN_KEYS   8
// Known keys, see: https://code.google.com/p/mfcuk/wiki/MifareClassicDefaultKeys
byte knownKeys[NR_KNOWN_KEYS][MFRC522::MF_KEY_SIZE] =  {
    {0xff, 0xff, 0xff, 0xff, 0xff, 0xff}, // FF FF FF FF FF FF = factory default
    {0xa0, 0xa1, 0xa2, 0xa3, 0xa4, 0xa5}, // A0 A1 A2 A3 A4 A5
    {0xb0, 0xb1, 0xb2, 0xb3, 0xb4, 0xb5}, // B0 B1 B2 B3 B4 B5
    {0x4d, 0x3a, 0x99, 0xc3, 0x51, 0xdd}, // 4D 3A 99 C3 51 DD
    {0x1a, 0x98, 0x2c, 0x7e, 0x45, 0x9a}, // 1A 98 2C 7E 45 9A
    {0xd3, 0xf7, 0xd3, 0xf7, 0xd3, 0xf7}, // D3 F7 D3 F7 D3 F7
    {0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff}, // AA BB CC DD EE FF
    {0x00, 0x00, 0x00, 0x00, 0x00, 0x00}  // 00 00 00 00 00 00

I have no idea what to fill in here...
I guess something with this information but I don't know how to and where I have to fill this information in.
Card code information, in the serial monitor:

ScCC to see UID and type...
Scan PICC to see UID and type...
Card UID: 7A 6F BA 56
Card SAK: 08
PICC type: MIFARE 1KB

If you are using the cards uid (which is different in every rfid card) then im sorry but you cant duplicate it simply because the producers are locking the card but there are some tags that allow you to do it and you can get them for cheap but if you are not using the uid and using the data that is written inside you can change it using an app

I think I have cards without a lock, look I have slaves (or mastercard, don't know what it's called).
And these tags: http://www.bpn-groep.nl/wp-content/uploads/2015/06/rfid-druppel-keyfob-keytag.jpg

But I'm wondering what do I have to fill in in the hard-coded part of the code? From my Original to clone in a tag.

Anyone?

You're not asking a programming question.
There are many experts here to help you with programming solutions.

You're asking an RFID card cloning question.
Only those with that kind of experience (which may be very few) could help you.

Yes I am asking a programming question, I want to know how to get this information in the code...

No.

At the very least you need to state your legitimate reason for wanting to clone a card. Otherwise why should we help you break the law?

I said it in the thread..
'duplicate a certain pass where I can acces my stuff with.'
Not breaking the law lol, I want to copy my locker pass for school :P, so I have 2, and I just want to figure out how it works, not to break the law..

Grumpy_Mike · December 14, 2016, 6:08pm

If I told you how to do that what is to stop you cloning the tag of some one else and steeling their stuff?
There should be no legitimate reason for doing this.
If you want two tags to the same locker then it is simple to enroll another tag to open that locker as well.

akatchi · December 14, 2016, 6:10pm

Is there a way I can prove you that I'm not lying?
I only want to clone my pass, I want to learn how it works; no not to steal someone else stuff and clone. Just only my school pass.

Grumpy_Mike · December 14, 2016, 7:17pm

If I were to tell you what is to stop other people from abusing that information.
Much better if you pick a project that you can actually understand what is going on and build something useful.

akatchi · December 14, 2016, 7:30pm

No sorry I really want to do this project, and I want to know what is going on actually, can't you just explain me on private? Like how and why would I abuse it, I'm just an arduino fan just like many other people here. I'm not a guy that steals someone pass to clone it..

What you should do is after it print out:
"Try the most used default keys to print block 0 to 63 of a MIFARE PICC.
1.Read card
2.Write to card
3.Copy the data."

put your card on the top of the reader, then in the serial monitor enter 1 or 2 or 3 (1 is to read card.....)
then the function will work

J-M-L · May 18, 2020, 8:57am

it would be a shame if the school was not using some secure tags for locker access and just the UID of the tag.. I doubt you'll be able to clone a card without the management key that your school probably keeps safe, even if you have fully rewritable cards.

Grumpy_Mike · May 18, 2020, 11:04am

"Try the most used default keys to print block 0 to 63 of a MIFARE PICC.

Go home and stop trying to do illegal things.
Don't resurrect old threads.
