RFID Reader and
Price
At a high
level, RFID is an e-tagging technology that can be used to provide
electronic identity to any object. Electronic information about an
object is stored in RFID chips embedded or attached to the object.
Using an RFID reader, the electronic identity (code in the form of
several bits of data) can be read wirelessly using radio waves. This
is where it differs from other e-tagging technologies such as
barcode scanning, which uses optical recognition. Because it uses
radio waves, no line of sight is required and RFID tags embedded
inside an object can be sensed. Let’s see RFID Reader + Price in
some more details.
Further, an
RFID reader can read multiple RFID tags simultaneously, which is not
possible using barcodes. RFID Reader + Price at the gate of a
warehouse, for example, can immediately sense all the RFID-tagged
objects within a container as soon as the container passes by the
gate. RFID tags can either be passive (cheap and work without any
battery) or active (costly, yet have an embedded power source).
Further, the electronic identification stored in a tag can either be
fixed or dynamically updatable. The range of sensing RFID tags from
an RFID reader can vary from a few centimeters to a few meters
depending on the frequency of operation and the type of
tags.
Some more
information about RFID Reader + Price: Radio frequency
identification or RFID is gaining momentum in other parts of the
world, but has yet to make a real dent here because of its high
cost. There are a wide number of manufacturers of both RF tags and
RFID reader technology. The design and manufacture of the reader
antenna is normally the responsibility of the systems integrator.
The price of an RFID reader varies from $50 to more than $1,000,
depending on its size and the distance it covers - how far the
reader can be from the tag for data to keep transmitting. The price
of RFID readers varies between £1,800and £18,000, depending on the
type of reader.
RFID (Radio
Frequency Identification) is - like the bar code - a data carrier.
The difference is that the bar code reader needs contact with the
cluster of bars, whereas RFID operates on radio waves and does not
require a line of sight. At its simplest an RFID transponder is
silicon chip (the memory) mounted onto an antenna (the transmitter).
Its information is scanned by an RFID reader that sends energy in
the form of radio waves to the transponder, which can thus send its
information to the reader. The reason for the reduction in the
reception time of the goods previously mentioned is that several
hundred RFID transponders can be read at the same time. This the bar
code cannot do.
RFID will not
replace the bar code immediately. One hurdle is the price i.e. RFID
Reader + Price. Today a transponder costs from 20 cents to one euro
depending on the level of functionality and the package. In any case
even the cheapest transponder is around five times more expensive
than the traditional bar code. The effect of the price cannot,
however, be computed quite so directly.
RFID technology
adoption will happen in two stages. In the short- to medium-term,
RFID costs will not have dropped enough to apply the technology for
item-level tagging. At this level, RFID would find its way into
supply chain applications involving container-level tagging,
warehouse automation, etc. As the price point begin to dip down to a
few cents, new market opportunities will open up, especially in
sectors such as apparel, manufacturing, delivery and
pharmaceuticals. The market for RFID solutions could explode once
RFID costs have fallen below the single-cent level and new
technologies drive RFID sizes smaller, making them appropriate for
item-level tagging. Forrester Research predicts that by around
2007-2008, adoption of very cheap RFID tags (sub-$0.01 level) could
explode to over 20 to 40 billion RFID
tags.
