If you run a little business and would like to start taking payments by card, iZettle is by far the cheapest, easiest and newest way to do so. For £20 you get a card reader that attaches to an iPhone, iPad or Android mobile, then away you go. It'll be just like working in Tesco.

iZettle is launching with mobile network EE here, which will be selling the device, and including £20 of credit toward transaction fees, in some of its physical branches. In return you get a little card reader able to accept the 'chip & pin' cards offered by Visa, Mastercard, American Express and the Diners Club, with an upper limit of £5,500 a day. Which should just about cover an emergency plumber call-out.

For little businesses and the self-employed, it sounds like the perfect way to take money off people without having to march them to a cashpoint. iZettle says 4,000 people have already been using it in the UK as part of a beta test that's been running over the summer, with users happy to pay a 2.75 per cent commission fee for the convenience of taking plastic.
