Father of RFID

RFID, or radio frequency identification technology, is an integral part of modern society, using the power of electromagnetic energy to automatically sense and track information in thousands of applications, from network and building security to monitoring inventory and sales to preventing auto theft, keeping tabs on library books, and running unmanned toll booths.

The technology uses radio waves for remote communication between a “tag,” which may be in the form of a sticker or a data card attached to a person, animal or object, and a “reader” or scanner. This allows for precise, efficient, remote tracking or monitoring of objects according to the data contained on the tags.
