Radio Frequency Identification (RFID)

Radio Frequency Identification also known as RFID, is a part of technology that uses radio waves to transfer data from an electronic tag called RFID label, attached to an object, through a reader for the purpose of finding out and tracking the object. These RFID tags can be read from several meters away. It is all stored electronically. The tag does not use batteries to run, they use radio energy transmitted by the reader for its energy source.

RFID can be used in many ways and applications. A tag can be put onto any object and used to track and manage inventory and people as an example. For instance, they can also be put onto cars, books, and cell phones. The Health Care industry has even used RFID's. The most important part is that it is a system that involves certain hardware that is called interrogators, and tags.
