EZ Exchange is a smartphone application for which I created a mock up. It is designed for small businesses or even daily personal transactions. It works by connecting directly to debit accounts in order to make transactions fast and easy. You can set it up to wire directly into or out of your account, depending if you are buying or selling. If your friend owes you $50, you can simply enter the amount, scan their debit card, and have them enter their pin number. And voila, your $50 is back in your account without the use of cash.
