I didn't know RFID would also encroach on my burger meals. Even though I tend to avoid junk food (my paunch is still the same) but once in a while I do like to gorge on some burger and cola. In order to get more tech savvy McDonalds is testing e-coupon system in Japan.

Dubbed as Kazasu coupon it deploys RFID technology enabling customers to select their meals and pay for them using their cell phones. The payment application needs to be downloaded on the phone and placed near rfid readers placed at the store to make their purchases.

Since the concentration of RFID based phones is pretty high in this tech savvy country one could expect this system to meet with success as expected. It's not just about offering convenience to customers from standing in queues but also earn a few extra bucks by delivering user specific ads on their mobiles. Just another way to woo customers in RFID style!!
