Radio Frequency Identification Device – RFID
Radio Frequency Identification (RFID) is the utilization of
radio waves to recognize objects. Unlike barcodes, in RFID one can find a
product without virtually coming in touch with it. The tracking number is
stored in a microchip, which is connected to the aerial. The chip is then
enabled to put on the air any tracking data to the receiver. Finally, the
information will be converted into a digital format, which is read by the
computers.
A usual Icode Slix RFID
tag holds a microchip attached to an aerial escalated on a substrate. The data
storage capacity of a chip ranges from 64 bits to 2 kilobytes. E.g.,
information about manufactured goods or consignment date of production, and
destination, can be downloaded to a tag.
A reader is necessary to recover the data stored on an RFID
tag. A reader is a device, which has one or more aerials that releases radio
waves and take delivery of signals reversed from the RFID tag. The reader then
forwards the data into digital form to the attached computer.
RFID Advantage
Whether you are related to tracking records in a warehouse
or keeping a large bunch of apparel assortments, there is a requirement of a
completely automated data receiving and evaluation system which will help out
to sustain track of precious assets and equipment.
RFID technology offers exclusive solutions to hard data
tracking of records or equipment- specifically in applications, where
optical-based systems do not succeed and when write/read capabilities are
necessary. The technology is constantly developing, with unlocked designs
becoming more and more accessible.
Benefits of RFID vs. Barcode
The barcode's optical nature needs labels that can be
detected by lasers. The straight line between reader and labels is usually
difficult, not practical, or even unfeasible to attain in an industrial
atmosphere. In a move to achieve proper functionality, a barcode reader
requires clean and clear optics, the label must be spotless and free of
scratch, and the label and reader must be rightly oriented to each other. On
the other hand, RFID technology makes tags enabled to read from a larger
distance, even in the worst environments.
Additionally, the data imprinted on a barcode is set and
cannot be distorted. On the other side, RFID tags have electronic memory as
same as the common computer or digital camera to hold data and this can be
changed or updated dynamically.
RFID presents particular features which are not accessible
with any other automatic identification technologies. Albeit, not all RFID
systems offer every single feature, the following are a few common advantages
of RFID.
·
Enduring identification or read/write ability
·
Do not require contact or straight sightline for
reading
·
Practical resistance from incomprehensible
paint, dirt, etc.
·
Automated functioning
·
A broad range of tag alternatives and
frequencies
·
Reading capability ranges from a few inches to
several feet
·
Tremendously high data reliability
RFID Applications can be used in many trades other than
retail, which includes animal recognition, supple production (tracking and
control), laundry tracking, asset identification, and many many more.
