RFID systems
basically consist of three components: Antenna, Transceiver (with decoder),
and a Transponder (usually called RF Tag). The latter is composed of an antenna
and a chip that, electronically, is programmed with certain information. techsupportreviews
The antenna emits a
radio signal activating the RFID Tag. In fact, the antenna will serve
as the medium capable of making the RFID Tags send the information to the
reader. The antennas exist in different sizes, and each
configuration has different characteristics, each one indicated for a type of
application.
There are solutions
where we have the antenna and in the same device is the transceiver and the
decoder. This type of configuration is used, for example, in mobile
applications. In this case, the antenna and transceiver set is
called a reader.
The reader, through
the transceiver, emits radio waves that are scattered in various directions in
space, from an inch to a few meters, depending on the output power and the
radio frequency used.
When the RFID Tag
passes between the electromagnetic zone generated by the antenna, it is
detected by the reader. The reader decodes the data that is encoded
in the RFID Tag, passing it through the computer for processing.
RFID Tag is
available in various formats and sizes. They exist in the format of
tablets, rings, cards, rectangular, and others, and the materials used for
encapsulation can also be plastic or glass. The type of RFID tag is
defined according to the application, use environment, and performance.
How do RFID tags work?
One
of the maximum critical components for you to enforce the modern RFID era
within the production chain of a company is undoubtedly the use of RFID-kind labels, with a purpose to be
chargeable for accompanying the products, to move applicable data to the
identical.
Due to the advantages of this
type of automatic identification system for individual merchandise, experts say
that in the coming years, 95% of
world products
will travel accompanied by RFID-type tags.
This projection has arisen due to
the evaluation of the behavior and functionalities offered by RFID technology
in the productive sector. The great advantages of RFID tags lie in
their slim and flexible format, practically unbreakable, and in the extensive
information storage space they provide, thanks to the use of chips with
different memory capacities.
