This, from what I could understand, sounds illegal. As someone who has posted here more than once, I'd expect you to know that we don't help others hack things illegally. Also, if you really want to go at it, look up the hardware specs to see if a USB is even possibly compatible with it. Then, disassemble the driver (if there is one (if not, you're going to have to somehow bust through (I'm thinking buffer overflow?))), then figure out how it connects to the host, then change the values, then you're golden. Any of the specifics of that, we won't help you with.

We are clearly going to need some of the numbers off the chip. Give us a picture(with readable numbers) of the chip or all the number on it.

Does it have a way to connect a usb cable to it(besides cutting a usb cable open)? I doubt it.

I'm going to be honest. This will be very difficult(without the right experience). Most likely the chip is a simple micro controller, which to reprogram would require some external hardware(JTAG, ect) which is not going to be a simple set up. The reprogramming of it may be difficult because without a reader it may be very hard to know what it does specifically. You might be able to find this information online but I've never heard of the place you're talking about so it might not be popular enough for someone else to have done this then uploaded it.

Hopefully it's something a little simpler.

Another concern would be how the money is put on the card. I would be extremely surprised if the actual amount was stored on the card. Most likely the card holds user information that links to a database that holds the amount. You could get around this by being an asshole and using someone else's account.

I would have expected it to be an RFID chip. If it is, you do actually have a chance at this. RFID is notoriously insecure. You would probably have to buy a little equipment though to reprogram it.

As mentioned this is certainly illegal. But I don't give it much of a chance(IE 0) of you succeeding. I would still be interested in that chip though.

It was good until the mention of money being added onto it. Come on now, that is obviously going to cause a lock. Like shaqywacky said though, I seriously doubt the money is stored on the card.

How blunt.. If LoGiCaL__ didn't lock this, I would have locked it even harder. But hardware hacking like that takes some serious knowhow. Along with that, it'd probably be a lot funner.

it has no company name to it


Then you are pretty much(Read: completely) fucked. Unless you plan to hack their website, find out where they buy these chips from then use that companies information to figure out what type of chips these are. Even then you still have almost no chance.

I'm sorry. As it turns out companies like their money and for that reason they don't install 'hack' buttons on their hardware. Unless you can give us some more information, we have ABSOLUTELY no way of helping you short of finding another card and doing it ourselves.

take a pic of the chip and upload to imgur or somewhere so we can see it
