Radio Frequency Identification or RFID is the use of radio waves to identify
objects. This means, unlike a barcode, one can track an item without actually
having to come in contact with it. The way it works is that an identifying
serial number is stored in a microchip which is then attached to an antenna.
(Together these are called the transponder or tag.) The chip is now able to
transmit any identifying information to the receiver. The reader will convert
the information to a digital format to be read by computers.
A typical RFID tag consists
of a microchip attached to a radio antenna mounted on a substrate. The chip can
store from as little as 64 bits to as much as 2 kilobytes of data. For example,
information about a product or shipment—date of manufacture, destination and
sell-by date—can be written to a tag.
To retrieve the data stored
on an RFID tag, a reader is required. A typical reader is a device that has one
or more antennas that emit radio waves and receive signals back from the tag.
The reader then passes the information in digital form to a host computer
RFID Benefits and Advantages:
ability to eliminate time consuming bar-coding or other tracking processes.
Instead, all data can be collected along the production line. This also
helps to lower production costs.
of the distribution of counterfeit products.
Elimination or reduction of theft and loss.
of supply chain cost.
Elimination of data entry and other tedious manual business process
efficient order fulfillment process.
spent in check out lines, as consumers will only have to push their shopping
carts in front of the readers.
RFID offers specific
features not available with other Automatic Identification technologies.
Although not all systems offer all features, below are some common advantages of
Permanent identification or
immunity from obscuring paint, dirt, grease, etc.
Wide range of
tag options and frequencies
from several inches to several feet (depending on the system)
RFID Applications other than
Animal (livestock and domestic) identification, Flexible manufacturing (tracking
and control), Asset identification, Laundry tracking, Vehicle
Identification/Electronic Toll Collection, Parking and access control.
