Twitter co-founder Jack Dorsey is working on a dongle for your iPhone that turns it into a credit-card reader. Imaginatively called the Square, it's a little plastic widget that fits in your headphone jack and comes with an app. When you want to buy something, the employee enters the shop and amount details, then you swipe your card and sign on the screen. Your receipt is emailed to you, with a handy map of where the shop was. CNET News has the full story here: Twitter co-founder's 'Square' comes into focus.
