What is RFID?
RFID – Radio-Frequency Identification – uses electromagnetic fields to identify and track data contained within an RFID label or tag. These tags contain a microchip as well as a radio antenna which enables the tag to send its ID to a corresponding reader. Each microchip contains a unique code – called the tag identifier - registered by the manufacturer during the production of the microchip. The chip can store and transmit data to other equipment within the system.
As well as tags and readers, RFID systems also include a database and software for processing the data. Our RFiD Discovery software can be integrated with other systems to streamline processes throughout your organisation.
Active and Passive RFID
Active and Passive RFID tags offer different benefits and have distinct roles for the purposes of tracking items. Active RFID tags are powered by battery and proactively broadcast their own signal. They have the ability to track real-time locations and typically have a much longer read range than passive tags. Passive RFID tags do not contain a battery and power is supplied by the reader to enable the tag to transmit their ID, as well as offer a more cost effective solution for larger RFID Deployments.
