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.
An optical keypad assembly to access a car, comprising:
A method for accessing a car by using an optical keypad assembly comprising a plurality of keys, each key comprising at least an emitter for emitting visible light and an associated receiver for receiving reflected visible light, and a processing unit for controlling emitters and receivers and for determining if a key has been selected by analysing signal generated by the receiver of said key;
