Square UP was showing their new credit card processing solution for the iPhone. They are planning on offering a no-hassle way for individuals to start accepting credit card payments. Simply buy their $1 app from the App Store, sign up for service, and they will send you a small hardware dongle that will swipe credit cards (shown right). No individual merchant account is required as Square UP handles all the processing and payments and takes a 2.9% cut of all sales.
