Abstract
An NFC-based method for controlling an electronic device to perform a pre-determined action in a batteryless manner is provided, comprising the steps of providing at least one near field communication (NFC) tag which comprises a integrated circuit configured to activate the electronic device to perform the respective pre-determined action after the circuit is energized and an antenna electrically coupled to the integrated circuit and configured to harvest NFC energy from the electronic device to energize the integrated circuit; forming an operation loop comprising one of the at least one NFC tag; switching the operation loop between an operative state wherein the antenna is capable of harvesting the NFC energy to energize the integrated circuit, and a non-operative state wherein the antenna fails to harvest the NFC energy so as to disable the integrated circuit. A corresponding apparatus and applications of the apparatus are also described.
