Technology

Radio Frequency Identification (RFID) is a wireless technology capable of identifying and counting a diverse range of objects, without contact or line of sight.

RFID enables automated, handsfree communication between objects and computers.

RFID overview

• ‘Re-writeable’ memory - each tag has a small memory that can be read from and written to many times, allowing information associated with a tagged object to be changed;
• Unique code - the identification code stored in each tag is unique and unalterable, providing unambiguous identification of products and assets;
• Secure transactions - secure reading and writing to a tag prevents unauthorised modification of a tag’s memory;
• Fast data capture - large numbers of tags can be read quickly and without error, thus minimising human involvement and automating data capture;
• Rugged technology - RFID is a rugged, durable technology that continues to operate in the challenging conditions typically found in industrial environments.

The use of RFID allows hundreds of individually tagged objects to be uniquely identified and counted in less than a second, over ranges that can vary from near contact, to many metres. Typical applications include: supply chain logistics; manufacturing automation; library systems and rental services; livestock management; and vehicle immobilisers.
