Looking to use your iPhone as a main tool for your business? Then why not turn it into a mobile credit card transaction terminal so you can accept cashless payments on the go. That’s exactly what the Square credit card reader does.

There’s a dongle you attach to the earphone jack where you can swipe the card, and the accompanying app then requires the user to enter the amount and signature of the payee. The receipt will then be emailed to the buyer while geotagging is used in recording each transaction. It sounds really interesting, but you should be aware, though, that there’s a surcharge to the service and it’s not yet commercially available as it is still currently in its early alpha testing stage at the moment. Nonetheless, this looks like a very promising accessory for those who love using their iPhone and have a mobile business to run as well.
