What will they think of next? Soon if you want to accept credit cards at your garage sale there will be an app for that. A project named Square is now in alpha testing and expects to allow iPhone users to process credit card transactions for a fee.
The money transfers directly to the bank account of the merchant and the purchaser receives an email receipt. As seen in the photo from Cool Hunting above, the credit card reader is an accessory that simply plugs into the headphone jack of the iPhone or iPod Touch.
