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.
