RFID Overview

RFID uses Radio Frequency Communications to exchange data between a portable memory device and a host computer or PLC. An RFID system typically consists of a "Tag/Label/PCB" containing data storage, an Antenna to communicate with the Tag, and a Controller to manage the communication between the Antenna and the PC or PLC (the terms Reader or Reader/Writer are used when the Antenna and Controller are housed in one combined unit).

An RFID System Consist of Three Main Components

  • Tags / Labels / Printed Circuit Boards (PCB)
  • Antennas
  • Controllers

Some Uses For RFID

RFID tags can be placed where a normal barcode would be impractical. For example, in wet conditions or where vandalism could take place. They can also be read at difficult angles (no line of sight is needed)
The same RFID tag used to manage inventory can also be used to prevent theft.

The advantages it offers include 100% read accuracy, the ability to survive demanding environments, and the elimination of line-of-sight requirements.
In most environments, RFID can achieve 99.5% to 100% first-pass read rates. Maintenance is not an issue as there are no optical or moving parts. The demands of industrial environments are favorable for RFID.
