MasterCard has gone beyond Google Wallet to show a new mobile platform that could use multiple mobile technologies to solve mobile payments. Known collectively as QkR, they focus on QR codes for mobile payments but also audio cues, NFC short-range wireless, and even Microsoft's Kinect for the Xbox 360. One system would have an NFC 'coaster' that could recognize products shown on TV and let users tap an NFC-equipped phone or tablet on the coaster to buy whatever's on TV.
