Radio Frequency Identification
(RFID), the technology of the future, has long established itself in our
everyday lives. It is already deployed in various areas ranging from efficient
inventory management and road toll collection through to timing the performance
of individual participants in mass sporting events. With its enormous potential
it is only right that RFID is on everyone's lips.
RFID technology builds a bridge
between the physical world of a product and the virtual world of digital data.
The technology thus meets the demands of companies cooperating in a closely
knit value chain and is being deployed promisingly in all sectors of the
economy. RFID will soon be considered an indispensable part of the chain.
RFID - An Overview
RFID or Radio Frequency
Identification is a system that uses radio waves to transmit an object's
identity. There are several methods of identifying objects using RFID, but the
most common is to store an ID or serial number that identifies a specific
product along with other information, on a tag, which is a small microchip
attached to an antenna. The antenna enables the chip to transmit whatever
identification information it contains to a reader. The reader converts the
radio waves from the RFID tag into digital information that software systems
can use for processing.
Typically, when a reader reads a
tag, it passes three things to a host computer system: the tag ID, the reader's
own ID, and the time the tag was read. By knowing which readers are in which
locations, companies can know where a product is, as well as what it is, and by
tracking the tag data by time, they can know everywhere it's been.
Most industry analysts argue that RFID
tagging is a transformational software development activity that will ultimately change
the way businesses plan, price, distribute, and advertise products. But for the present, enterprise application vendors are extending their products to handle an expected boom in RFID data.
Until recently, a bar coded item used to sit on a retail shelf and did not
generate any data until it was scanned by a bar code reader. And then the data
was read only once. RFID, on the other hand, is a passive technology that does
not require human interaction to scan. A reader can extract location and product description data from a tagged item every 250 milliseconds. Some readers are capable of
reading data from 200 tags per second. The result is a data increase of more
than one thousand times above traditional scanning methods.
With the rate at which the market competition is rising, inefficiencies in a
company's value/supply chain and their continuous efforts to shore up internal
security are driving the rising demand for RFID. The retail trade is playing a
decisive part in the broad-based roll-out of RFID projects. RFID represents an all-encompassing structural business concept that far transcends simply superseding
the bar code. Considering the current scenario, RFID systems are rapidly
gaining significance. This holds especially in areas where they can be used to
manage processes within the value chain. With this favorable situation, the
market for RFID systems are likely to grow globally from EUR 1.5 bn to
EUR 22 bn between 2004 and 2010 (average growth rate: +57% p.a.). During the
same period, the RFID market in the EU-15 is expected to expand from EUR 0.4 bn
to EUR 4 bn (+47% p.a.).
RFID is such an intriguing
business concept, as it cuts inventory and supply chain costs through its
implementation. The ultimate goal is for RFID to replace barcodes. RFID allows
for individual product identification, not for product line identification like
barcodes. If this takes place, individual products can be read letting stores
locate those items if needed. Stores can also track when items leave the store
allowing them to easily replace items when one is purchased.
Furthermore, shipments can be
easily and quickly sorted and accepted by the receivables department. With the
reader, products can be received without even opening the pallet cutting
logistical needs. Obviously RFID
is a great tool for the supply chain and companies wishing to better track
their products and inventory.
