RFID Tags from The Premo Group

Radio-frequency identification (RFID) is a technology that uses communication via electromagnetic waves to exchange data between a terminal and an object such as a product, animal, or person for the purpose of identification and tracking. Some tags can be read from several meters away and beyond the line of sight of the reader.

Radio-frequency identification involves interrogators (also known as readers), and tags (also known as labels).

Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio frequency (RF) signal, and other specialized functions. The other is an antenna for receiving and transmitting the signal.

There are three types of RFID tags: passive RFID tags, which have no power source and require an external electromagnetic field to initiate a signal transmission, active RFID tags, which contain a battery and can transmit signals once an external source ('Interrogator') has been successfully identified, and battery assisted passive (BAP) RFID tags, which require an external source to wake up but have significant higher forward link capability providing greater range.

RFID has many applications; for example, it is used in enterprise supply chain management to improve the efficiency of inventory tracking and management.

Premo’s RFID tags represent the latest in RFID technology and their state-of-the-art designs are in use worldwide at Fortune 500 companies either in complete RFID systems or installed on important assets whose movement or location must tracked or logged in real time.
