RFID Definition from PC Magazine Encyclopedia

Definition of: RFID

RFID

(Radio Frequency IDentification) A data collection technology that uses electronic tags for storing data. The tag, also known as an "electronic label," "transponder" or "code plate," is made up of an RFID chip attached to an antenna. Transmitting in the kilohertz, megahertz and gigahertz ranges, tags may be battery-powered or derive their power from the RF waves coming...

Electromagnetic Waves

Michael Faraday proposed in 1846 that both light and radio waves are part of electromagnetic energy.

In 1864 James Clerk Maxwell published his theory on electromagnetic fields and found that electric and magnetic energy propagate in transverse waves at the speed of light

In 1887 Heinrich Rudolf Hertz produced and studied electromagnetic waves. He concluded that...
