RFID, short for Radio Frequency Identification, is a technology that uses electromagnetic fields to automatically identify, track and manage assets. This technology operates on a defined protocol that enables the storage and retrieval of information remotely via tags, cards, and similar devices.
RFID operates by sending a signal to a microchip, which then sends back information to a receiver, allowing for easy and fast identification of items. This technology allows for the wireless retrieval of data, enabling objects to be tracked and managed without direct contact or line-of-sight scanning.
RFID technology has found applications in a wide array of areas, such as RFID asset tracking, RFID inventory management, access control, supply chain optimisation, personal identification, and security.
An RFID system consists of three critical components:
RFID tags are small devices embedded with a microchip and an antenna designed to store data about the item to which they are attached.
RFID tags can be classified into three types based on their power source:
RFID readers are devices that communicate with the tag to read or write data. It sends out a radio frequency signal that activates the tag, allowing data to be transmitted back to the reader through the same radio frequency wave. The reader then decodes this information and passes it to a computer system for processing.
RFID readers can be handheld, mobile terminals, wireless, Bluetooth or stationary units, depending on the application needs.
Antennas are crucial components of RFID readers and tags that emit and receive radio waves. The antenna’s design, including its shape and size, influences the effective range and directionality of the RFID system.
An RFID warehouse tracking system is an advanced technology-driven solution to optimise warehouse operations by using RFID technology to accurately track and manage inventory and assets.
