Let us start the discussion by
explaining the meaning of RFID and further how this works with some
excellent examples for its applications.
What is meant by RFID tags:
RFID is an acronym for the
Radio Frequency Identification. RFID tags are used as a type of
tracking system which uses smart barcodes. The barcodes are used to
identify specific items. RFID tags thus utilise the technology of
radio frequency. The radio waves transmit the data contained in the
tag to a reader. The reader will further transmit the data to a
computer program of RFID. These types of tags find wide use in
merchandises. However, these can also be widely used for tracking
vehicles, for tracking patients, pets, etc. The RFID
hard tag dealers in Kolkata can
supply a high standard of hard tags which can be used for several
purposes. This type of tag is also known as RFID chip.
How an RFID tag works:
RFID tags work by using an
antenna and microchip by suitably transmitting and receiving the
information. The information is written suitably on the microchip for
providing the necessary information to the readers. The Sensor gate dealers in Kolkata
can provide the excellent type of hard tags which can perform very
well as well as last very long. Two main types of RFID tags are
generally available. These are passive and battery operated tags.
While the battery operated type of RFID tag contains a battery as the
source of power supply, the passive type of tag does not use a
battery and instead works through the electromagnetic energy which
gets transmitted from the RFID reader. The battery operated RFID tags
supplied by the RFID hard tag dealers in Kolkata is also popularly
known as active tags.
Working with the passive RFID tags:
There are three main
frequencies used for working of the passive RFID tags. These are low
frequency between 125 to 134 kHz, High frequency at 13.56 MHz and
high frequency between 865 to 960 MHz The range of operation of the
tags are affected by the frequency used in the tag. A passive tag
transmits information to a reader by getting the necessary energy
while being scanned by a reader. The reader further sends this
information to an RFID computer program which interprets the data
suitably. The passive tags are comprised of hard tags and inlays.
While the inlays are thin tags, the hard tags are quite durable and
can be made of metal or plastic. The excellent quality of such tags
supplied by the Barcode
Scanner dealers in Kolkata
has brought a huge credential for the supplier.
Working principle of the Active RFID tags:
The active RFID tags operate
on two frequencies. These frequencies are either 433 MHz or 915 MHz
and these two frequencies are used for transmitting information. Tag,
Antenna and the interrogator are the three main parts for such type
of tags. The battery of such active tags should last for at least 3-5
years.
The use of RFID tags:
There are several uses of the
RFID tags supplied by the RF
Hard tag dealers in Kolkata.
These type of tags can be used for vehicle tracking applications, for
tracking the movement of the merchandise in a retail shop or a mega
mart, for tracking expensive product from a long range, etc. The
choice of EAS System
dealers in Kolkata
has proved very beneficial for Businesses to make the operation more
efficient.
