| Radio frequency identification, or RFID, is a
generic term for technologies that use radio waves to automatically identify
people or objects. There are several methods of identification, but the most
common is to store a serial number that identifies a person or object, and
perhaps other information, on a microchip that is attached to an antenna (the
chip and the antenna together are called an RFID transponder or an RFID tag).
The antenna enables the chip to transmit the identification information to a
reader. The reader converts the radio waves reflected back from the RFID tag
into digital information that can then be passed on to computers that can make
use of it. |
| RFID is also called Dedicated Short Range
Communication (DSRC). RFID is a wireless system used to identify tags. These
tags may be carried by people or animals or mounted on object or vehicles. They
may even be embedded under the skin. RFID systems can be used just about
anywhere, from clothing tags to missiles to pet tags to food -anywhere that a
unique identification system is needed. The tag can carry information as simple
as a pet owners name and address or the cleaning instruction on a sweater to as
complex as instructions on how to assemble a car. |
| RFID technology can be divided as Active and
Passive at the highest levels. Active technology (Active RFID Tags) requires a
power source, they are either powered by integrated batteries or a powered
Infrastructure. On the other hand Passive technology (Passive RFID Tags) do not
require batteries and also have a larger operational life. This consists of the
semi – conductor chip attached to the antenna and the Tag Reader is responsible
for powering the antenna and communicating with the Tag. |
| RFID Technology is set to become the frontrunner
technology for automatic identification and data collection. The applications of
RIFD can be spread across almost all industry verticals such as; |
