RFID power from handset transmissions

摘要

A radio frequency identification (RFID) tag comprises a transceiver and a component coupled to the transceiver. The transceiver is adapted to wirelessly receive power from an RFID reader and/or from a mobile communication device. The power received from the mobile communication device is used to power the component, providing an alternative power source (cellular beacons) that uses no additional handset power.
