A new device has been launched which allows users to swipe credit and debit cards on their iphone.
It's called ‘The Square’ and is the brainchild of Twitter founder Jack Dorsey.
It’s thought that it will appeal to small businesses and travelling sales reps who might need to make or take payments on the go.
The hardware works by plugging into the phone’s headset socket and uses a signature on the touch screen to verify the transaction.
It’s been set up to work with Visa, Master Card, and American Express and it’s hoped will also take Discover or Diner’s Club in the near future.
