Square is a new innovative way that lets people authorize, accept, and process credit card payments through their mobile devices. It includes features like email receipts, payer verification and repeat customer rewards.

To function, Square requires two different components. The first is an application  that will be available for your phone. The second component is a fairly inexpensive dongle that plugs into the headphone jack. At launch, the Square service will be compatible with the iPhone and devices running the Android operating system.

The Square service won’t have any contracts, monthly fees, or hidden costs. They will even donate a penny after every transaction to a cause of your choice. Square hasn’t mentioned the cost per transaction, but this could definitively be a hit if the number is low.
