A person identification device 100 has a tag 110 with a code and a tamper evident tether 120 able to secure the tag 110 to a person having a body. The person identification device also has a signal generator 140 able to generate a signal representing the code. The tag 110 has a capacitive contact 130 able to capacitively couple the signal into the body of the person.

A lock system for access authorization in a motor vehicle, having a first device which has at least two states and is embodied as a control device, and having an associated second device which is embodied in the manner of an electronic key, an ID signal transmitter, a chip card or the like. The two devices have transmitters and/or receivers for electromagnetic signals. At least one of the signals transmitted between the second device and the first device is an encoded operating signal for authenticating the second device, with the result that after a positive evaluation of the transmitted operating signal when the second device is authorized it is possible to bring about a change in the state of the first device.

A method for accessing a vehicle includes determining a charge level of a battery of a first vehicle access device. The method also includes creating a permission scheme for a second vehicle access device. The method further includes communicating the permission scheme to a vehicle and accessing the vehicle with the second vehicle access device.

A smart key searching apparatus includes a start button for selecting engine start or stop, a wireless charger performing wireless charging in a resonant magnetic coupling manner and transmitting an authentication request signal to a smart key, a radio frequency (RF) receiver receiving a response signal regarding the authentication request signal transmitted from the smart key, and a smart key controller requesting, when the start button is operated, the wireless charger to search for a smart key, and controlling power and engine ignition of a vehicle according to a response signal received through the RF receiver.

A system, device and method for opening an electromechanical system of a vehicle. The system includes a capacitive emblem switch and a transponder, where the transponder includes an identifier of the vehicle. The capacitive emblem switch is activated when the user is in proximity of the vehicle with the transponder. The electromechanical system, such as a rear hatch of the vehicle opens when the user motions in front of the activated capacitive emblem switch. In embodiments, the capacitive emblem switch may be incorporated into a vehicle logo or a vehicle model number. In an embodiment, LED lights are used to indicate activation of the capacitive emblem switch. The LED lights may change color to indicate a completion of the method. The capacitive emblem switch may be transparent. The transponder may be a key fob.
