RFID and its close cousin Near Field Communications (NFC) have both been touted for great and sexy futuristic applications. These range from the tagging and tracking of all consumer goods to the conversion of mobile phones into all purpose 'Super wallets' where simply waving the phone at the checkout would pay for the items. The idea with RFID is quite simple. If one can apply sufficiently low-cost tags to items can replace the line-of-sight constrained barcode with something that can be read automatically over a range of a couple of meters.
