RFID technology is not only changing how cars are built, but also how they are driven. The tolling industry has long relied on RFID transponders to ease congestion at toll booths. In the U.S., this is primarily done through bulky transponders that attach to car windshields.
However, RFID tags are being embedded into windshields and license plates in Europe, which not only allows for tolling, but enables easy and secure entry in parking garages and payment at gas stations, while deterring license plate theft.
Of course, RFID-enabled vehicles also add to safety on the roads, particularly with a new use case being developed by NXP. In the scenario, a RFID tag embedded into a pedestrian’s backpack interacts with traffic lights that also serve as RFID readers. When the reader senses the tag, it alerts approaching vehicles of the pedestrian, and signals for the light to turn red. Imagine the use cases for students walking to and from school, or for highly congested roadways with heavy pedestrian usage.
