Ever since the first
electronic article surveillance device was installed in
retail setting 30 years ago retail security technology has
played an important role in store applications.
With inventory shrinkage
costing organizations hundreds of millions of rupees each
year, organization have increasingly turned to technology such
as EAS or tagging system and video surveillance to control
theft and inventory management system.
AS retailer demand has grown
so has the technology. The first somewhat large anti theft
tags have evolved into today’s wafer like labels that’s can be
attached or inserted in to variety of items. As EAS technology
has become more sophisticated, organizations now have much
more flexibility with their systems, with the promise of much
more innovations to come.
For manufacturers &
retailers, the potentials applications and benefits of RFID
technology are far reaching. Systems enable companies to
protect and manage their assets more efficiently through
identifying and monitoring movements, providing significant
enhancements to inventory control and management, Successful
integration of such system into day today working is fast
becoming a necessity to manage inventory and reduce overheads.
Organizations also stand to
benefit from the efficiencies that RFID have brought to access
control systems and to automation of traditional more
cumbersome time and attendance systems well-established
applications in many other industries. RFID personnel
identification can be further extended to restrict and control
access to tills, overcoming the loopholes inherent in
traditional password protection and drawer locks.
With tags on products,
inventory counting and stocktaking and marking, stock down
will become faster and more accurate. More detailed and up to
date product information reduces the risk and costs associated
with out of stocks and obsolescence. Receiving bays, automated
counting results in more efficient checking.
Significant benefits stand
to be had in the automation of returns. Ultimately, the
concept of Self-Checkout stands to become a reality, when
readers at the till will identify the contents.
What is Smart RF_ID Tag?
RFID uses radio frequency
transmission to identify, categorize, locate and track people,
animals and objects. RFID systems are composed of three
components –an interrogator or reader, a transponder, commonly
called a tag, and a computer or other data processing system.
The tag is plaid on or in the object you want to identify or
track. There is no need for contact or a direct line of sight
between the reader and the tag. This means that tags can also
be imbedded in or hidden inside objects that need to be
RFID readers have electronic
components that send and receive a signal to and from the tag,
a microprocessor that checks and decodes the data it receives,
and memory that stores the data for later transmission if
necessary. The reader has an antenna to transmit and receive
signals. The antenna is enclosed with the reader electronics.
The main component of the
RFID tag is a custom integrated circuit or silicon chip. This
chip controls the communication to the reader. The chip has a
section of memory that stores the identification code or other
data, and the content of the memory is transmitted to the
reader when the chip is activated. The tag has an antenna to
the chip and a tuning capacitor. The amount of data stored in
the tag can range from 40 bits unique fixed code to 1kbits of
IN this system , the reader
emits an electromagnetic field in a zone of which depends on
the operating frequency of the system and size of the antenna
. when tag passes through this zone , the tag detects the
signal from the reader and begins to transmit the data stored
within the tag back to the reader. The signal generated by the
reader provides timing information as well as enough energy
to provide power to the tag .
The significant advantage of
all types of RFID systems is the non contact , non line of
sight nature of the technology . tags can be read through a
variety of substances and in visually and environmentally
challenging conditions , where barcodes or other optically
read technologies would be use less.
What is a Smart RF-ID tag”?
Businesses around the world
are using RFID Technology to give themselves a competitive

Technical Specifications of
the “ Smart RFID Tags”
RFID System consists of
transponder and read/write unit. Both have internal
intelligence and an antenna that receives, sends and stores
data. the read/write unit -e.g. computer palmtop.
The read distance of common RF-id Systems –passive systems
without battery – is typically I foot on a desktop reader and
I meter –between 3 and 4 feet- on gate reader.
The necessary components –
integrated circuits and antennas – are specially chosen to fit
the needs of mass – market applications 13.56 MHz is a world
wide frequency supported by may organizations for an
international RF-id standard.
Common Applications with our
Item management and
identification –asset tracking-
Protection against fraud.
With reusable facility in
comparison to barcode , paper tags , stickers etc, the RFID
technology is far superior.
The proposed Solution
The common problem faced
inventory management and asset tracking. We propose to
automate both through ONE RF-ID SMART TAG for ease of working.
All the products are tagged
with RFID Smart Tags . the storage capacity of the tag will be
of 56/ bytes tat are reusable , the electronic data to be
stored in the tag is the product code, product details ,
issuance details and other required information. As the
antenna and the chip is concealed inside the tag not visible
the visual area can be printed with the customer logo or any
visuals desired by the customer.
The tags can further be
reprogrammed for reuse.
The whole process on
automation drastically brings down the time consumed in issue
and receipt by cutting down manual processes of verifying the
contents , further it also minimizes the possibility of human
error intentional or unintentional and automates the complete
asset management process making online availability of data to
various departments for better control and MIS generation for
The process can be fine tuned
to suit the requirement of the customer on system study of his
work environment and present problems faced in his working
environment for better control and management which will lead
to overall efficiency and increasing in revenue.
specifications “ Smart RFID TAGS “ are as follows.
