Finding applications for RFID

All the talk was around RFID at this week's RFID World in Boston where a lot of the focus was on using second-generation active and passive radio frequency identification tags to provide security and authentication. Up for discussion was the idea of how the average wireless device could soon become an RFID reader or how it could be integrated to give a mobile user easy access to all kinds of data. One attendee told Computerworld that he was investigating how to incorporate RFID technology into cell phones which could be used like a "fast track" or "speed pass" to quickly have a credit card authorized for purchasing fuel or food. MIT also showed off some technology from its labs, including an application that allows someone with diabetes to read his or her blood sugar level with a cell phone that's set up to receive data from an arm patch.
