A brilliant idea! Now you can quickly and easily accept credit cards from your iPhone. All you need is the card reader, and you are ready to go. Squareup.com provides these reader free of charge (at least for now) and simply charge $.50 and 3% per swipe. Not the cheapest in the world, but about the same price as PayPal. I hope I get into the beta test soon. I can’t wait to try it out.
