You can now make payments through your local brick-and-mortar retailers using the Square credit card reader through your Apple iPhone! Soon available at Apple’s retail stores and official website, the device allows you to plug a retailer’s reader from a retail outlet or online and insert it into the iPhone 4. Once plugged into the iDevice, you will need to download the free Square app from the App Store and employ the offering without entering into contracts or paying monthly fees. Compatible with the iPhone 4, the fourth generation iPod touch and the iPad, the Square credit card reader helps users track sales and taxes and transfer of receipts. No more lines, no more waiting!
