iPhone with a credit card swipe in machine.

Question

Hello friends,
I wonder how can we connect a iphone device to credit card swipe-in machine .Thus, any user swipes the card through credit card swipe-in machine,all the credit card details get transferred and stored in the phone device that can be used to confirm the payment transaction by user. The user can even use these as complete transaction details later.

All ideas are welcome !!

There are a couple of these on the market already. The most popular (in the press) is called "Square" and is a small square that mounts in the headphone jack.

There are others out there that look like an iPhone case with a magnetic strip reader.
