Abstract: A system is provided for vehicle access. Advantageously, the present system includes 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 includes a capacitive sensor for a standby mode. The capacitive sensor shape limits the induction with the RFD antenna. The present system therefore proposes a new access system for which the installation is fully reversible and not harmful to the vehicle.
