mag card hacking

8 posts in this topic

I hope someone here has some experience with mag cards. After a lot of delay due to school and work, I finally got my card reader working. I sucessfully swiped track 2 of my school ID and figured out what is on it. I modded the reader and now I am trying to read track 3 using stripe snoop.

The problem is, every time I swipe track 3 in raw mode, I get a different output. Each swipe is similar from the last, but sometimes I will get double the numbers outputed the last time I swiped. I tried swiping the card 5 times right in a row and every swipe outputed something slightly different.

Is this an error in the reader? Or is this just a fact of life, that the data encoded on the card can be misred sometimes and I'll have to figure out which swipe is the correct data. If it is the latter, any tips on doing so? Thanks

Since I only have a two track swipe, I can't offer any tips to read track 3. However it sounds like whatever mod you did to your reader in fact borked it. If this is an ID for a university or similar, track 3 probably contains information about your student monies (meal plan, money in your campus account, etc).

i've also only got track 2 readers, but out of 5 swipes and everyone is different? I'd agree with him and say something is messed up with the reader.

Are you sure you modded it right? If you messed up and its reading both track two and three due to incorrect size placement or how you are swipping it, then mod it again.

I opened the side of the swiper, unscrewed the magnetic head, and moved it to the position for slot 3, and screwed it back in. I've since moved it back to the 2nd track position and it still reads track 2 correctly.

From my research I have figured out that track 2 contains a number similar to a credit card number that is linked to a database. Each swipe of an external door, or swipe into the cafeteria, runs this number against the database to see if I can access the building or the cafeteria. That is all using the Diebold/CBORD campus card system.

Track 3 is used for gaining access to my dorm room. It is an Onity door system similar to the one seen in hotels. The data on track 3 is encrypted and does not conform to ISO standards. http://www.onity.com/index.php?x=1&y=2&z=5&n=13

If you have an engineering part of your school, that might be why. Engineers = Hackers! :P

Ohh, and if you live in Jersey, mind reading my id to see what they say? (I also need a barcode reader for devry, cause I think more then the id number is on it...)

Now all you need to do is find a card of someone you dont like, swipe it, and then write their card info onto your card...free lunch (woot)

My old school had a computer connected to the lunch swiper, so the person swiping the id can see a picture of the person on the screen as well as the id picture. If they don't match...

What you can do without getting in trouble like that is use it to get into their dorm and if there is a student debit account tied to it, use that at vending machines, laundry machines, the student stores (Beware cameras!), etc.
