All Square-d up!
Ever had someone owe you money but they had no cash on them and only a debit/credit card? Well now if you own a iPhone, iPad, or iPod Touch you can get paid by the card with an app called Square!
If you sign up to the free Square service available at Squareup.com you can get a free card reader that plugs into the audio jack of your device which allows cards to be swiped. Card details can be entered into the app manually if no reader is present. Receipts and photo verification are included with the service so users are sure of secure transactions with signatures signed on the iPhone screen. Square makes money by taking a small percentage of each transaction, currently 2.75% +15 ¢ with the card present and 3.5% +15¢ when the card number is keyed in.
