This document discusses RFID (radio frequency identification) technology and its applications. It begins by explaining what RFID is and its basic components. It then discusses the different types of RFID tags and provides examples of current applications in various industries like access control, asset tracking, transportation, and retail. The document also presents results of an online survey that showed benefits of RFID for manufacturing, retailing, transportation and warehousing industries. It concludes by discussing future development opportunities for RFID and both positives and limitations of the technology.

3. RFID

RFID = Radio Frequency Identification

Electronic labeling and wireless identification of objects using radio
frequency

Tag carries with its information


Model number


a serial 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

4. RFID components

A basic RFID system consists of these components:

A programmable RFID tag/inlay for storing item data;

Consisting of an RFID chip for data storage

an antenna to facilitate communication with the RFID chip

A reader/antenna system to interrogate the RFID inlay

Application software and a host computer system

5. RFID Tag

The RFID tag consists of an integrated circuit (IC) embedded in a thin film
medium.

Information stored in the memory of the RFID chip is transmitted by the
antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID
reader

3 types

Passive

Semi-passive

Active

6. Types of RFID Tags
Active Tags
• Use a battery
• communicate over
distances of several
meters
Semi-passive Tags
Passive Tags
• Contain built-in
batteries to power the
chip’s circuitry, resist
interference and
circumvent a lack of
power from the reader
signal due to long
distance.
• They are different from
active tags in that they
only transmit data at
the time a response is
received
• Derive their power from
the field generated by
the reader
• without having an active
transmitter to transfer
the information stored
