This document provides a theoretical framework for using RFID technology in the retail sector. It begins by discussing the historical development of RFID from the 1940s to present day. It then explains the basic components of an RFID system including tags, readers, and databases. The document outlines several benefits of RFID for retailers such as reduced costs, improved inventory management, and theft prevention. It also discusses various applications of RFID technology in areas like supply chain management, logistics, and retail store operations. In conclusion, the document states that while RFID offers advantages, limitations around costs and technology maturity remain barriers to wider adoption.
3. The great usage of intelligent technologies such as
wireless networks and Radio- Frequency Identification
(RFID)(Kourouthanassis and Giaglis,2005) has moved
during the past decade from labs and niche uses into a
broader range of application(Slettemeas,2009).
4. According to Kotler & Keller (2006), retailers
are improving their skills in demand
forecasting, merchandise selection, stock
control, space allocation, and display with
use of IT. For example, supermarket chains
are using scanner data to manage their
merchandise mix on a store-by-store basis.

6. of RFID
Radio-Frequency Identification
(RFID) technology can be
defined as an a wireless sensor
technology which is based on
the detection of electromagnetic
signal(Domdouzis et. al.,
2007:350) .

Tesco.
8. According to Ngai et. al (2008) RFID technology developed
rapidly by American originated companies such as Wal-Mart,
and European companies such as Metro and Tesco, has
caused other companies to take a great attention for what
RFID can do for them and whether they should give further
consideration for adaptation .
Regarding the Chow et al. (2006) RFID uses the radio waves
to identify objects and this technology has been widely applied
in numerous areas in the supply chain activities such as
manufacturing and distribution of physical goods, shipping and
port operations and inventory management.
9. Components of RFID
In general RFID system has three basic components as
an RFID tag (transponder), a reader (transceiver), and a
database (Slettemeas, 2009:221).
Radio frequency identification (RFID) is a small tag
which contains an integrated chip and an antenna to
send radio waves transmitted from the RFID reader in
order to process, and then store information.
10. RFID Tags
As stated before the tags have an importance for the right
RFID technology solutions. According to Ngai et. al (2008)
the tag has an identity (ID) that can be broadcast to a
reader that is operating on the same frequency and under
the same tag protocol RFID devices are known as tags and
they fall into two broad categories: those with a power
supply (a battery) and those without.
11. The main blocks of the RFID tag are the following (Ashry et.
al.,2009:1504):
Rectifier: This block rectifies the input RF signal and generates the
needed DC voltage to power the other blocks of the system.
Demodulator: This block is the receiver of the system that detects
the commands sent by the RFID reader.
Control logic: This is the digital part of the system that controls all
other blocks of the system.
Internal clock: This is an internal clock generator that supplies an
internally generated clock to the digital part.
Modulator: This block is the transmitter of the system that sends
the tag ID to the RFID reader.
12. Readers
The reader consists typically of a transmitter and
receiver, a control unit and a coupling element
(antenna) to interact with the transponder (Dastoori
et. al.,2009:468). RFID reader is a device that can
read data from and write data to compatible RFID
tags.
13. Read Ranges and Tag Frequency
In general, frequency allocations are
managed through legislation and regulation
by individual governments. Internationally,
there are differences in frequencies allocated
for RFID applications although
standardization through ISO (International
Organization for Standardization) and similar
organisations is assisting in compatibility.
14. For RFID application, there are generally
three frequency ranges. (Roberts, 2006: 20).
The frequency of transmitting information is a
key factor in determining performance levels
and applications for the system. Almost, all
RFID systems operate on one of four
frequency bands: low frequency (LF), high
frequency (HF), ultra high frequency (UHF),
and microwave (MF) (Tajima, 2007: 262).

application of RFID are (European Policy
Outlook RFID, 2007):
Manufacturing and production (e.g., the
automotive industry),
Transport and logistics
Retail and consumer goods
Public transport
Health care

17. Table 3: The Overview of RFID Technology Applied in Various Industries
18. Benefits of RFID Usage
RFID technology has an opportunity to enterprise wide
technology with inter-organizational implications in the
same tendency as the Internet and networked PCs. This
can bring both business process and society fundemantal
changes.
RFID’s recent advances have enabled its early adoption
in many commercial applications, such as supply chain
management, logistics, and transportation. Because
businesses expect to get better efficiency, accuracy,
visibility, and security performance in the supply
chain(Ustundağ and Tanyas, 2009; 37).
19. Application of RFID In Retail Sector
The timing and magnitude of the RFID adoption and
related process redesign have become more critical than
before as businesses strive to use RFID technology at an
unprecedented rate (Lee and Lee, 2009:313).
At first RFID entered into retail businesses in order to
optimize delivery logistics, solve out-of-stock problems and
improve the supply chain (Fleisch et al. 2005, Fleisch and
Mattern 2005, Fleisch and Thiesse 2007, Loebbecke and
Palmer 2006, Mattern 2005, Murphy-Hoye et al. 2005,
Resatsch et al. 2007a).
20. There are also given potential use of RFID at the palet and case
levels throught the value chain, from manufacturer to point of sales
(POS) (Loebbecke, 2005:5):
Product Transport: Manufacturer or retailer affixes RFID tags to
all product pallets and cases before they are shipped. The tags are
electronically time-stamped and then entered into the central
computer of the retailer’s RFID goods tracking system. The tagged
pallets and cases can thus be identified and located along the
entire logistics chain, all the way to the sales floor.
21. Leobbecke(2004) also stated RFID tagging on item and he
discussed about RFID’s oppurtunities for retail sector by tagging
items:
New types of services in stores, such as personalized
advertising displays and self-check-out, aimed at increasing
customer loyalty and promoting sales.
Electronic price labeling in stores, making price tags easer to
understand and more current.
Improved theft protection in stores, because products cannot be
taken out of this store without payment
22. Warehouse Dispatch: Goods ready to be shipped to a
store are taken from the central warehouse to dispatch
area. As they pass through the exit gate, an RFID
transceiver reads the codes on the pallets and cases and
passes this data on to the RFID goods flow system. The
goods then have the status of “on route to destination”.
23. Goods Delivery to the Store Stockroom: RFID helps match
arriving goods to orders. When a truck arrives at a store, its
pallets are once again identified by an RFID reader, which can
handle as many as 35 pallet or case tags per second. The goods
are then registered as “in the store stockroom”.
24. Warehouse Management and Storage Processes: Once
received, the goods flow system registers the goods at being in the
stockroom. Each storage location has an RFID tag, which is stored in
the RFID goods flow system along with the RFID numbers of the
pallets and cases stored at each location.
25. Transport of Goods into the Sales Room: RFID
readers, located at the store stockroom exit doors,
identify every palet and case that is moved into the
store. These readers send the relevant RFID numbers to
the RFID goods flow system, which identifies the
products as “ transported into the store”.
26. Standardization of RFID
The International Organization for
Standardization (ISO) has created standards
for tracking cattle with RFID. ISO 11784
defines how data is structured on the tag.
ISO 11785 defines the air interface protocol.
ISO has created a standard for the air
interface protocol for RFID tags used in
payment systems and contactless smart
cards (ISO 14443) and in vicinity cards (ISO
15693). It also has established standards for
testing the conformance of RFID tags and
readers to a standard (ISO 18047), and for
testing the performance of RFID tags and
readers (ISO 18046).
27. Advantages of RFID Usage in
Retail Sector
Levy and Weitz(2003) stated main
advantages of RFID usage in the retail sector
which are:
Reduced warehouse and distribution labour
costs. Reducing manuel labour intensive
operations with sensors tracking
shipments(items)can reduce labour cost by
30 percent.
28. Reduced point-of-sale costs. The main saving are due to
reduced labour hours needed to check inventory and
facilitation of self-scan checkouts that is shortening
checkout times.
Inventory savings. Less inventory errors. Companies do not
need to review inventory as frequent as previously and
informations about current levels of stock are much more
accurate.
29. Elimination of counterfeited merchandise. With RFID tag on the
original merchandise it will be much harder for counterfeiters to
sell fake merchandise to retailers.
Facilitation of selling process. Retailers install RFID readers in
stores with digital displays to help consumers in their search for
product of interest or to provide them with information about
certain product. Consumers will also be able to see availability
of the indifferent colours and sizes. Furthermore it can also
facilitate cross-selling.
30. Reduced theft. Not just in the store but through the
whole supply chain RFID can be used to minimize
opportunities for theft. Small and valuable items carry
RFID tags in the stores. RFID tags are attached to high
value apparel to prevent shoplifting while a customer
tries them in the dressing room etc.
Reduced out of stock conditions. Product tracking
enables real time response to decreased stocks either in
the warehouse or on the store shelves.
31. Conclusion
RFID technology is being used for a number
of purposes. A significant area of its usage is
the retail business.
In addition to its functional benefits, RFID
provides a significant advantage for retailers
regarding inventory management. Although,
RFID has remarkable advantages, yet there
are some barriers to wider implementation of
this technology. RFID is still an immature
technology. To be become a well established
and widely accepted technology, like the
barcode system, RFID needs further
development.
32. Choosing the right technological
infrastructure is extremely important. The
main burdens of this technology are its
relatively high installation cost and, currently
the limitation of using a tag only once in a
product. RFID technology seems to make a
significant progress within a decade.
33. By giving theoretical framework of RFID in
retail industry, we want to provide useful
informaitons about RFID technogy usage in
retail sector for new researchers.
Espeacially, for researchers who live in
countries that there are no any usages of
RFID technology in business world. For
example, In turkey there aren’t any usages of
RFID technology in retail sector but it will be
expected for both manufacturers and
suppliers.
