Where does this come from, and can I check it?

Passive RFID tags derive electrical power from the reader's radio signal to broadcast data. The figure is taken from NIST Information Technology Laboratory, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.

Is this really a technology fact?

Yes. It sits on the Technology shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.

What else can I read about it?

The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.

Mondo Knows Facts

RFID tags communicate asset data wirelessly using electromagnetic fields

Passive RFID tags derive electrical power from the reader's radio signal to broadcast data

Radio-frequency identification uses microchips connected to small wire antennas to store data. Passive RFID tags contain no internal battery; instead, they capture electrical energy from an incoming radio interrogation pulse sent by an RFID reader. RFID tags enable automated supply chain tracking, contactless payment cards, and electronic transit passes.
