HEllo!

The copy machine cards used in copy machines at schools/universities - blank on one side and a magnet stripe (sized 1/3 of a credit card stripe) on the other side, very thin cards , fully bendable as paper. You put the card inside the box attached to the copymachine and your value in the card is displayed.

So i know you can copy a credit card with a reader/writer , how to hack this type of cards ? To add more value to it for free copying?

I use the copy machine alot. copy whole books, so save a lot of money.

Ok. got some photos. http://i124.photobuc...o_/DSC00014.jpg

1: Is a access card same size and type as a bank/credit card.I have just showed it here for comparing with the copy machine crads.

2:The card is a copy card from a library, you buy with a value.ex.10 copies.

3:Is a copy card from the university, you buy it with a value, example 10 copies.

The reader on both university and the library copy machine is sized as a portable harddrive for pc.you put the card in and it has a display which shows the value of it.

Card 1:

As you can see it is hard to bend, its made of plastic.Same as credit card. Visa/Mastercard etc.

Card 2:

As you can see its not the same type its made thick paper, and the magnet stripe on this looks like its printed with ink if you look closely on it. hard to see in the picture.

Card 3 is of same type but you can see that the stripe is not ink but glued on as magnetic stripe.

I know you can use a writer like these on card 1:
http://search.ebay.c...c stripe writer

But you need so expensive witer on the copy machine cards?

Or can you do something with the card so when you put it in the machine it only reads and cant write to it so it dont change value?
Something that work like some liquid or tape on it?

Get a reader/writer (most standard 3track ones will do) and post the output of the data from the cards. (btw, I have been thinking about this very same thing since last year.....copies cost $0.40 cents for godsakes....)

So i have to buy the same writer as used on the plastic cards/credit cards?

Is there any forum who deals with copying magnetic cards?

I'd start off by making your own cheap reader just to see what datas on the card. It would suck to find out all thats on there is an account number after you'd bought a card writer. If the data conforms to an ISO standard you're in luck because you'll be able to verify you got a good read, otherwise you'll have to be careful making the swipe and do it a few times to check for errors.

There are two main types of writer hi-co (hi coercity) and lo-co (hi coercity), lo-co is a alot cheaper and will be able to other write the data on a lo-co encoded card, but not a hi-co encoded card. It will be able to read both. Those cards usually have the magnetic strip 'printed' on in a kind of slurry and encoded at the same time. I have no idea if they're hico or loco though.

Readers will usually read indiscriminately so even if it is hico encoded as long as you could get some blanks/loco encoded ones you wouldn't have to buy a hico reader.

Hello!

Are you guys sure a magnetic card reader can read this card:

Since where i live we have to swipe a card to come in the building, there is a photo of the card in my first post. And when i swipe the copy card with the small stripe in the reader the reader doesnt react tried it on two door readers they dont react.

So you think a card reader for computer will read it even the stripe is so small in width and the card is of paper not plastic`?

Thats a magnetic stripe bro, so as long as you can move it correctly across the pickup head it should translate back into data. A lot of card readers are three tracks, that card probably isn't, but as long as you line up the track with the pickup I think it will capture correctly.

Your problem will not be the reading, it will be the writing, I don't know a cheap way to encode magnetic stripes.

I've also seen one track card readers on ebay for cheap, keep updated on what you find out.
