|Title: ||RFID Technology|
|Authors: ||Abhishek Anand|
|Issue Date: ||4-Jan-2011|
|Abstract: ||Radio-frequency identification (RFID) is a technology that uses communication via
electromagnetic waves to exchange data between a terminal and an electronic tag
attached to an object, for the purpose of identification and tracking. Some tags can be
read from several meters away and beyond the line of sight of the reader.
Radio-frequency identification involves interrogators (also known as readers),
and tags (also known as labels).
Most RFID tags contain at least two parts. One is an integrated circuit for storing and
processing information, modulating and demodulating a radio-frequency (RF) signal, and
other specialized functions. The other is an antenna for receiving and transmitting the
There are three types of RFID tags: passive RFID tags, which have no power source and
require an external electromagnetic field to initiate a signal transmission, active RFID
tags, which contain a battery and can transmit signals once an external source
('Interrogator') has been successfully identified, and battery assisted passive (BAP) RFID
tags, which require an external source to wake up but have significant higher forward link
capability providing greater range.
There are a variety of groups defining standards and regulating the use of RFID,
including: International Organization for Standardization (ISO), International
Electrotechnical Commission(IEC), ASTM International, DASH7 Alliance, EPC global.
(Refer to Regulation and standardization below.)
RFID has many applications; for example, it is used in enterprise supply chain
management to improve the efficiency of inventory tracking and management.|
