KEYPAD ASSEMBLY AND METHOD TO ACCESS A CAR

摘要

The present invention provides a system for vehicle access. Advantageously, it comprises an optical keypad and an RFID antenna working through a windscreen which can be athermal including a thin metal layer. The keypad measures the reflection of visible light on the fingers of the user. The keypad assembly has very low power consumption as it comprises a capacitive sensor for a standby mode. The capacitive sensor shape limits the induction with the RFID antenna. The present invention therefore proposes a new access system for which the installation is fully reversible and not harmful to the vehicle. Indeed it does not need to cross the car body or any joint.
