Abstract
A battery-free smart key with infrared system (IR) comprises a receiving coil, a side controller, and an infrared data association (IRDA) communication transmitter (TX) module. The receiving coil is able to receive electromagnetic waves with a wireless power and a certification data transmitted from an outside system. The side controller is used for processing the certification data and distributing the wireless power transmitted from the receiving coil. The IRDA communication TX module is coupled to the side controller and is able to transmit an IRDA communication signal with at least one certain user information. When the security entry system receives the correct IRDA communication signal, a door or an entry system can be unlocked. A car entry with IR system combined therewith is also disclosed.
