RFID tag in car

The use of RFID in car are access control, vehicle identification, vehicle tracking.

Access Control – The ability to allow or deny access based on a vehicle having a specific RFID tag is a valuable way to provide a building or parking lot an enhanced level of security. These systems keep out unauthorized vehicles that would otherwise take up space and deters individuals from entering a secure building or lot. Thousands of RFID vehicle access control applications are operative in apartment/housing complexes, secure parking lots, construction yards, etc.

Vehicle Identification – The ability to identify a vehicle and access information about it by reading its RFID tag is a beneficial for companies like car rental agencies, car dealerships, and even car wash facilities. With the addition of software, these companies can pull up car records or purchases by just reading the car’s unique RFID tag. Rental companies and dealerships could have several cars on the lot that are nearly identical, so the unique RFID tag provides them with vehicle identification without trying to find and compare multiple VINs. Car washes (and other companies using car servicing as a business model) can use RFID to uniquely identify cars to enhance loyalty programs and automate transactions. Additionally, states and localities use RFID systems to automate tolling charges and keep traffic flowing more smoothly for those participating in the program.

Vehicle Tracking – Tracking a vehicle while it is traveling hundreds or thousands of miles is not a capability of UHF RFID; but, if checkpoints are set up along the route, the location of the vehicle can be estimated based on when it passes each one. This is being done throughout the nation at large truck weigh stations along major interstates. When 18-wheelers are weighed, their RFID tags are read to pinpoint location and can also be used to document the journey. For companies or persons interested in tracking vehicles in real-time and without setting up expensive infrastructure, vehicle GPS tags are a better solution.
