You could write down the amount and item on a "receipt". Take a picture of both at the same time and then email your customers a copy if they wanted. This would give you physical proof that might be worth more than the carbon copy. This seems so obvious it’s probably stupid but why not just take a picture of the card?

You could change the string per event, increment per swipe, whatever you like. It's not cryptographically secure, but it's not in the clear.

But finding or writing a G1 app to use with this is on my list of things to check out once it's built. I haven’t, mostly due to not having an iPhone.

Still not as awesome as making a swipe thing. Good luck. Have you looked into the 50 different iPhone apps out there for accepting credit cards? Still not as awesome as making a swipe thing.
