A wirelessly charged battery powered electronic door locking system utilizes a first radio frequency to wirelessly transmit a wireless charging signal from an electronic control module to an electronic lock module mounted with the door. A rechargeable battery associated with the electronic lock module powers the electronic lock module and is recharged thereby. An RFID reader may be coupled to the electronic lock module, powered by the battery and mounted with the door.

A computerized system as disclosed herein for accessing a vehicle comprises a vehicle key comprising a control unit, a first wireless communication module operatively connected to said control unit and configured to allow said control unit to communicate with a control system of said vehicle, and a second wireless communication module operatively connected to said control unit and configured to allow said control unit to communicate with a mobile computerized device. The system further comprises a software application which can be stored on and executed by at least one mobile computerized device, said software application being configured to control said control unit to interact with said control system to cause the unlocking of one or more doors of said vehicle. In a further aspect, the invention relates to a computerized method for accessing to a vehicle.

An on-vehicle apparatus start verifying a first code of a portable apparatus returned from the portable apparatus in response to a first signal from the on-vehicle apparatus unless a battery of the portable apparatus is not exhausted upon detection of a user's operation to unlock/lock a door beside a vehicle; verifies a second code of the portable apparatus returned from the portable apparatus in response to power supply to the portable apparatus through electromagnetic induction caused by a second signal from the on-vehicle apparatus; determines whether the user's operation has been continuously detected if the first code is not returned; ends the verification of the first code if there is no state where the user's operation has been continuously detected; and ends the verification of the first code and starts the verification of the second code if the user's operation has been continuously detected.

Communications between a base station and a transponder that is powered by the base station are effected using a signal differentiation approach. A first radio frequency signal is communicated between the base station and the transponder to power the transponder, with the first radio frequency signal including noise and data for authenticating communications between the base station and the transponder. A second radio frequency signal is communicated between the base station and the transponder, with the second radio frequency signal including data for authenticating communications between the base station and the transponder. The detection of noise presented via the first radio frequency signal is mitigated while detecting data in the second radio frequency signal, via signal differentiation.

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.

An intelligent entrance guard unlocking method includes: transmitting electric energy of an intelligent entrance guard by wireless electromagnetic radiation via a transmit coil; receiving the electric energy via a receive coil of a powerless smart key; scanning an eye of a user to recognize an iris image of the user and storing the iris image in a second storage unit of the powerless smart key; controlling a wireless transmit unit of the powerless smart key to transmit a wireless signal containing the iris image to the intelligent entrance guard; obtaining a predefined iris image from a first storage unit of the intelligent entrance guard and comparing the iris image with the predefined iris image; unlocking the intelligent entrance guard when the iris image matches with the predefined iris image and not unlocking the intelligent entrance guard when the iris image does not match with the predefined iris image.

An intelligent entrance guard unlocking method includes: transmitting electric energy of a power unit of a intelligent entrance guard in a wireless electromagnetic radiation via a transmit coil; receiving the electric energy via a receiver coil of a powerless smart key; capturing a fingerprint image of an user and storing the fingerprint image in a second storage unit of the powerless smart key; controlling a wireless transmit unit of the powerless smart key to transmit a wireless signal containing the fingerprint image to the intelligent entrance guard; obtaining a predefined fingerprint image from a first storage unit of the intelligent entrance guard and comparing the fingerprint image with the predefined fingerprint image; unlocking the intelligent entrance guard when the fingerprint image matches with the predefined fingerprint image and not unlocking the intelligent entrance guard when the fingerprint image does not match with the predefined fingerprint image.

An intelligent entrance guard unlocking method includes: transmitting electric energy of a power unit of a intelligent entrance guard in a wireless electromagnetic radiation via a transmit coil; receiving the electric energy via a receiver coil of a powerless smart key; capturing a palm print image and storing the palm print image in a second storage unit of the powerless smart key; controlling a wireless transmit unit of the powerless smart key to transmit a wireless signal containing the palm print image to the intelligent entrance guard; obtaining a predefined palm print image from a first storage unit and comparing the palm print image with the predefined palm print image; unlocking the intelligent entrance guard when the palm print image matches with the predefined palm print image and not unlocking the intelligent entrance guard when the palm print image does not match with the predefined palm print image.
