To me, why not just use IPC Linea Pro? http://www.ipclineapro.com/ http://www.ipclineapro.com/ It works with iOS, provides a ruggedized housing and extra battery, comes with a barcode scanner, and encrypts your credit card number, and has a toolkit already for use with Xcode. You can sign up with Braintree or TrustCommerce and use their RESTful APIs. No extra charge. This device looks like it's easy to lose. I don't know. If I were a customer, I'd be sketched out by that thing. The ones at the Apple Retail stores (Linea Pro) look legit. EDIT: Opportunity for someone to make a product with IPC Linea Pro. Verifone's the only player. Why not add some stress with the Linea Pro device?
