Swipe card on an iphonePAYware Mobile is a card reader that attaches to an iPhone and lets you charge a credit card securely anywhere -- in a trade-show booth, at a silent auction or at the door to a ticketed event. Just swipe the card, have the guest sign using the stylus, and a receipt is e-mailed to the customer. The product is free with a two-year agreement (subscription, processing and merchant fees are separate; contact credit card firms for details; your firm might already have accounts set up with one or more of them).
