Radio Frequency Identification (RFID)
is over ten years old and is used in many applications including access
control, E-tags for motorways, microchips in pets and even in late
model car keys as part of an immobiliser.
The big growth in the use of RFID
is yet to be seen and we can expect the most significant increase will
be implemented in the areas of tracking, maintenance, transport and
logistics.
How does RFID work?
RFID is a means of identifying,
tracking and detecting an object using radio frequency (RF)
transmission.
Communication takes place between a
reader (known as an INTERROGATOR) and a transponder
(known as a CHIP connected to an antenna or more
frequently as a TAG).

Tags are either active
(powered by a battery) or passive (powered by the
reader field) and are attached to an object.
Every tag has a certain amount of
internal memory in which it stores information about an object. When these tags pass
through a field generated by an interrogator, they transmit information
back to the interrogator, thereby allowing identification and
communication.
Some types of RFID technology allow
information to be written and stored on the tag.
“Sensor tags”
can record “real world” data from
“on-tag” sensors and even more advanced active tags
can communicate with other tags in close proximity using integrated
“on-tag” transmitters.
What does TIG International do?
TIG International develops Mobile
Computing and Logistics solutions for all industries.
We have already integrated RFID
technology into some of our products and our research
efforts are providing us with genuine, practical information about the
reality of RFID technology.
We provide consulting, hardware products and software solutions for
RFID technology and can also provide full project management,
implementation and support services. We develop new solutions and
customise our existing solutions to satisfy any requirement.
