RFI: spy chip technology: "The supermarket chain Tesco has admitted testing controversial technology that tracks customers buying certain products through its stores. Anyone picking up Gillette Mach3 razor blades at its Cambridge store will have his or her picture taken.
One potential problem with RFID tags is that they can still work long after the product has been bought. If the tags become as ubiquitous as the manufacturers would like, people could be bristling with the chips in clothes and possessions. Anyone from police to potential thieves could work out exactly what they carry. Manufacturers, however, insist that the chips can be disabled at the point of sale.
.. Transport for London is also using RFID-style chips in its new Oyster smart cards to allow users to travel around the tube network. The intention is that registered users will have information such as their names and addresses stored on the cards, which would eventually replace season tickets. .. Nicole Carroll, marketing director for TranSys, the consortium responsible for implementing the system, told the Guardian that all the journeys made by a user would remain stored in a central computer for the lifetime of the card.
