  • Contactlessly rechargeable identification device and method thereof
    Patent number: 8072312
    Abstract: A non-contact state charging authentication device and a method thereof are disclosed. The authentication device includes: a power supply for receiving and transmitting power; a control unit for controlling a signal; a shunt and voltage divided circuit connecting to the said power supply and the said control unit for controlling the transmission of power; and an electromagnetic inductance element connecting to the said shunt current and voltage divided circuit for inducting and transmitting an electromagnetic signal which has an electromagnetic inductance frequency. While non-contact electromagnetic induction between the said authentication device and a charging device occurs, the said charging device begins to charging the said authentication device.
