Abstract

In an embodiment a method for supplying energy wirelessly by means of RFID comprises the steps of sending by an RFID reader device (10) a request message (100) to at least one RFID tag device (20), receiving by the at least one RFID tag device (20) the request message (100), sending by the at least one RFID tag device (20) an answer message (110) to the RFID reader device (10) and changing by the at least one RFID tag device (20) its state into a high power mode, receiving by the RFID reader device (10) the answer message (110), sending by the RFID reader device (10) an energizing signal (120) having an unmodulated constant wave at a predefined frequency during an adjustable amount of time, receiving by the at least one RFID tag device (20) the energizing signal (120), converting said signal into energy and using the energy by the at least one RFID tag device, and changing by the at least one RFID tag device (20) its state into an RFID operation mode at the end of the adjustable amount of time.
