Red Tomato, a pizza place in Dubai, has squeezed the store footprint to an extreme: two inches. Red Tomato gives customers a refrigerator magnet shaped like a pizza box to stick on their refrigerators.. A customer configures the magnet with a mobile phone, specifying favorite pizza and toppings, along with payment data to keep on file. Any time he wants pizza, he presses the button on the magnet, which uses Bluetooth to communicate with the phone, which sends a text message to Red Tomato. The customer gets a text back confirming the order and the pizza arrives soon after. No call, no clicks, no problem.
