RFID in McDonald's

Just read the blog posted by Bjarke Svendsen about the project of using RFID in Korea McDonald's. Here is the abstract of the post:



"Working with SK Telecom, McDonald's in Korea is testing food ordering by RFID (radio-frequency identification). A pilot program in Seoul's Shinchon neighbourhood lets customers place an order by pointing their cell phone at the items they want. Actually, it's not quite that simple—they first need to download software to their phone and then, seated at their McDonald's table, plug an RFID reader into the phone and aim their handset at a menu with built-in RFID chips. Items are automatically charged to their cell phone bill. As soon an order is ready, a message is sent to the customer's cell phone, letting them know that they can pick up their tray at the counter.
