This document discusses RFID technology and its applications. It provides information on active, passive, and semi-passive RFID tags as well as their operating frequencies and typical read ranges. Examples of current RFID applications are given for different frequency ranges. The document also summarizes RFID use in industries like manufacturing, retailing, transportation, and warehousing; and lists benefits such as enhanced customer satisfaction, improved efficiency, increased inventory turnover, reduced manpower, and reduced total cost.

3. • RFID = Radio Frequency Identification
• Electronic labeling and wireless identification of objects
using radio frequency
• Tag carries with its information
• a serial number
• Model number
• Color or any other imaginable data
• When these tags pass through a field generated by a
compatible reader, they transmit this information back to
the reader, thereby identifying the object

different from active
tags in that they only
transmit data at the
time a response is
received
