Conventional remote control functions for cars such as unlocking the trunk lid separately from the car doors, centralised door locking, and opening the side windows from afar are widely spread today increasing user convenience.

RFID-based remote control functions combine conventional remote control functions with enhanced security features. One example for a smart remote control function is automatic opening and locking of car doors when the RFID transponder resides in the range of the car enabling keyless entry. Equipped with advanced encryption standards, the transponders reliably prevent interception and spoofing of the transmitted signal.


Further functions that can be tied to the presence of an RFID transponder in the range of the car are security features such as activation of the alarm or anti-car-hijacking features.
