Inductively coupled RFID tags have been powered by a magnetic subject generated by the RFID reader. Electrical current has an electrical part and a magnetic part -- it's electromagnetic. Because of this, you can create a magnetic field with electricity, and you can create electrical present with a magnetic subject. The identify "inductively coupled" comes from this process -- the magnetic area inducts a present within the wire. You may learn extra in How Electromagnets Work. These have been meant to be disposable tags that may very well be utilized to inexpensive merchandise and made as universal as bar codes.
