Here's another iPhone application that is genius! If you are selling at remote locations and find that people don't carry cash and want to pay you by credit cards, this is an app for you.
Meet iphone app, Square which allows you to accept credit card payments through your iphone! All you have to do is type in the total amount, slide the customer's credit card through a small SQUARE device that plugs into the iphone's earplug hole, ask the customer to sign using their fingers, and voila! You've just made a sale by accepting a credit card. And customers can be emailed a receipt later on.
Square is use-friendly and easy to use for even people who are not technology savvy. Amazing eh?
