Very nice and everything, but if I went into a store and the payment method was via a device attached to an iPhone then alarm bells ringing "card skimmer" would be going off in my head and I'd walk out the door.
Why? Because I don't want the inconvenience. If I call up and complain about unrecognised charges then my card is cancelled, then I have to wait 5 business days minimum for a new card and also a new pin to be issued. If you want my business and my money then get a proper credit card processing terminal, there are plenty of other merchants around.
