Consider Long checkout lines at the grocery store…
It is one of the biggest complaints about the shopping experience. Soon, these lines
could disappear when the bar code will get replaced by smart labels (RFID) tags. RFID
is similar to barcoding in that data from a tag or label are captured by a device that
stores the data in a database. RFID tags are intelligent bar codes that can talk to a
networked system to track every product that you put in your shopping cart.
Radio Frequency Identification (RFID) is a technology that uses radio waves to
automatically identify objects, animals, and people. It is the wireless non-contact
technology that uses radio frequency waves to transfer data. Tagging items with RFID
tags allows users to automatically and uniquely identify and track inventory and assets.
Though, this is not a new technology and even older than Barcode. RFID has come a
long way from its first application of identifying airplanes as friend or foe in World War
II, 1970s.
Within the Electromagnetic Spectrum, there are three primary frequency ranges used
for RFID transmissions – Low Frequency, High Frequency, and Ultra-High Frequency.
RFID systems can be susceptible to certain materials and environmental factors that
can cause diminished read ranges and affect overall system accuracy. Metal and

liquids are the two most common sources of interference for RFID applications, but they
can be mitigated with the proper RFID tags, equipment, and planning.
RFID System:
A RFID system consists of a tag, which is made up of a microchip with an antenna, and
reader with an antenna. The reader sends out electromagnetic waves. The tag antenna
is tuned to receive these waves. While each system will vary in terms of device types
and complexity, every RFID system contains at least the following four components:
Tags
Readers
Controllers
The simplest system can be comprised of a mobile handheld RFID reader (with an
integrated antenna) and RFID tags, while more complex systems are designed using
multi-port readers, additional functionality devices (e.g. stack lights), multiple antennas
and cables, RFID tags, and a complete software setup.
RFID Tag:
RFID tags have similar applications to barcodes, they are far more advanced. An RFID
tag in its most simplistic form is comprised of two parts – an antenna for transmitting
and receiving signals, and an RFID chip (or integrated circuit, IC) which stores the tag’s
ID and other information. RFID tags are affixed to items in order to track them using an
RFID reader and antenna. Depending on the application, RFID tags & cards can cost
less than Rs.5 or up to Rs.150 per piece.

RFID Tags & Cards Types
RFID Reader:
An RFID reader is the brain of the RFID system and is necessary for any system to
function. Readers, also called interrogators, are devices that transmit and receive radio
waves in order to communicate with RFID tags. RFID readers are typically divided into
two distinct types – Fixed RFID Readers and Mobile RFID Readers. Fixed readers stay in
one location and are typically mounted on walls, on desks, into portals, or other
stationary locations.
An integrated RFID reader is a reader with a built-in antenna that typically includes one
additional antenna port for the connection of an optional external antenna as well.
Integrated readers are usually aesthetically pleasing and designed to be used for
indoor applications without a high traffic of tagged items.
RFID Controllers:
The brains of any RFID system are RFID controllers. Controllers are used to network
multiple RFID interrogators combined and to process the information centrally. In any
network the controller should be an application software or workstation running data
base. Controller uses the information gathered by the interrogators when new inventory
is needed in retail application and alert the suppliers.

RFID Applications:
What sets a potential RFID application apart from applications that can use other types
of systems is the need to uniquely identify individual items quickly and more efficiently
where traditional systems fall short. Below are a few applications that are successfully
using RFID technology.
1. Item level inventory tracking
2. Logistics & Supply Chain Visibility
3. Attendance Tracking
4. Materials management
5. Access Control
6. IT Asset Tracking
7. Kiosks
8. Library Systems
9. Laundry Management
10. RTLS (Real Time Location System)
New applications for RFID technology are constantly emerging to solve an age old
problems across industries. In the retail industry, every store has inventory which may
range into the thousands, even hundreds of thousands of pieces and dollars. Jewellery
stores have millions of dollars invested in thousands of earrings, necklaces, and
bracelets. With RFID jewellery tags, accurately tracking inventory becomes a viable
option.

By providing a cheap, efficient, and reliable way to collect and store data, RFID offers
limitless possibilities for current and future use. RFID has become, and will continue to
be more and more desirable for implementing applications at the service of our society
and humanity.
