PHILADELPHIA (CBS) - On today’s APP-tastic and outta SITE — ideal for any small business, it’s the Square app and credit card reader.

A tiny dongle plugs into your iPhone and when you swipe a credit card on it, the Square app processes the transaction. The fee is 2.75% per swipe but Square will foot the bill for the first month.

The app itself is free and works with iPhones, iPads and Android. The company promises robust security, too.

Check out the Square app.
