>>16402010First off every one saying you're a retard for trying to break the system, you're not some nigger trying to kick in the coin machine hoping quarters try to pop out(i've actually seen this.)
You're trying to manipulate a system in your advantage.
You have to find out how the machine reads the cards, how the money is put on the cards and then find out how to input your own data on the card. If the card works off a network it might be harder than just that.
Good luck, i doubt you will succeed though.
