Abstract
The present invention relates to transfer methods of wireless power to non-self-powered biometric authentication devices through far-field radio waves coming from a nearby self-powered radio frequency device. By default, the non-self-powered biometric authentication device of the invention is made of a far-field radio microwave antenna, an antenna tuner, a RF-to-DC power rectifier and power converter functions. The transfer methods of wireless power to non-self-powered biometric authentication devices of the invention are particularly well-suited for self-enrolment of one user's identity on biometric smart cards but can also be applied for subsequent data exchange such as peer-to-peer money transfer.
Claims6
A non-self-powered biometric authentication device comprising a far-field radio microwave antenna, an antenna tuner, a power rectifier and power converter functions in order to wirelessly power that same authentication device, during the initial identity self-enrollment phase and subsequent data exchanges, through far-field radio waves coming from a nearby self-powered radio frequency device.
