is RFID tags?
RFID tagging is an ID system that uses small radio
frequency identification devices
for identification and tracking purposes. An RFID tagging system includes the
tag itself, a read/write device, and a host system application for data
collection, processing, and transmission. 1
What does it consist of?
Most RFID tags are made up of at least two main parts. The first is
an antenna, which receives radio frequency (RF) waves. The second is an
integrated circuit (IC), which is used for processing and storing data, as well
as modulating and demodulating the radio waves received/sent by the antenna.2
What is the difference between a traditional bar code and
an RFID/EPC tag?
While their basic uses are similar, there are some important
differences between the old and the emerging product code systems:
rather than product-level tagging:
RFID tags: Because RFID/EPC tags
have a computer chip with its own electronic memory, each tag can have its own
individual identification code-this is beyond the capacity of the traditional
printed bar code symbol. Thus, RFID/EPC tags can separately identify
and track every individual item.
BAR codes: Bar codes, on the other hand, can only identify the product class
that an item belongs to.
RFID tags: Because
RFID technology uses radio waves, the tag’s signal simply has to be within
a certain distance, for the reader to make the scan-and reader and tag do not
have to make an individualized connection.
BAR codes: Traditional
bar code technology uses a light-based reader that must shine
directly on a tag to be read by the scanner.
How is RFID tags related to Accounting Information Systems?
Today’s accounting industry in the U.S. and Canada is no longer one
that just provides simple tax preparation services. Over the years, the North
American economy has experienced huge upheavals and an increasingly complicated
regulatory structure. These changes have affected the accounting business,
forcing firms to offer a broader range of services that trigger revenue growth.
At GAO RFID, we understand companies must be able to mobilize
quickly to keep up with today’s demands. We are experts in manipulating RFID
technology to suit a wide range of business needs. 3The
accounting industry has benefited greatly from our expertise. Allow us to do
the same for your firm, no matter how big or small your challenges may be.
Why RFID in Retail?
RFID technology goes beyond the basic self-checkout lines.
Now, as it continues to develop, RFID is being used to increase work efficiency
and boost sales, job satisfaction, and customer service levels.
Innovative retailer, Zara, has built their business around RFID.
They are now able to conduct a physical inventory in their outlets in about 15%
of the time it used to take.
RFID can be used in a variety of applications, such as:
of persons and animals
collection and contactless payment
dust (for massively distributed sensor networks)
baggage tracking logistics21
Timing sporting events
and billing processes
Advantages and Disadvantages of RFID tags:
tags are very easy to install/inject inside the body of animals, thus helping
to keep a track on them.
is better than barcodes, as it cannot be easily replicated, and therefore,
increases the security on a product.
chain management forms the major part of retail business, and RFID systems play
a key role by helping in managing the updates of stocks, and during the
transportation and logistics of the product.
tags are placed inside jewelry items in stores, and an alarm is installed at
the exit doors. If an unauthorized attempt is made to move the jewelry items
away from the premises, the alarm gets activated.
tags can store data up to 2 KB. This allows one to store a stronger encoded
identification series within it.4
proves to be too expensive for many applications as compared to other tracking
and identification methods, such as the simple barcode.
is difficult for an RFID reader to read the information in case the tags are
installed in liquid or metal products. The problem here is that, liquid and
metal surfaces tend to reflect radio waves, which makes the tags unreadable.
has been observed to take place in RFID systems, when devices such as forklifts
and walkies-talkies are in the vicinity. The presence of mobile phone towers
too has been found to interfere with these radio waves.
signal frequencies across the world are non-standardized. For instance, the US and
Europe have a different range of frequencies at which RFID tags function. This
makes it mandatory for international shipping companies and other organizations
to be aware of the working pattern in other nations.
is considered by many to be an invasive technology. Consumers tend to worry
about their privacy when they purchase products with these tags, as there is a
belief that once radio chips are installed in a product, it continues to track
a person, and his personal information can be collected by it and transmitted
to the reader.
Regulation and standardization:
A number of organizations have set standards for RFID, including:
Organization for Standardization (ISO).
Electro technical Commission (IEC).
ASTM International, the DASH7 Alliance.
There are also several specific industries that have set
guidelines. These industries include:
The Financial Services Technology Consortium (FSTC): which has set a standard for tracking IT Assets with RFID,
The Computer Technology Industry Association Comp TIA: which has set
a standard for certifying RFID engineers, and the International Airlines
Transport Association IATA which has set tagging guidelines for luggage in airports.
In principle, every country can set its own rules for frequency allocation for RFID tags, and not all radio bands are available in all
countries. These frequencies are known as the ISM bands (Industrial Scientific and Medical bands). The return signal
of the tag may still cause interference for other radio users.
