A quick overview of RFID labels
RFID labels are a type of smart label that incorporates RFID technology for tracking and identification purposes. RFID technology was originally developed during the second world war but its use has vastly increased over the last 15 years and RFID labels have incorporated this technology to become an essential tracking and identification tool across various industries.
What does an RFID label consist of?
An RFID label consists of four components:
1) RFID microchip - The RFID chip makes up an inlay along with the antenna, this chip stores the data related to the item it is attached to. Which includes information such as product name, price and location.
2) Antenna - The antenna which makes up an inlay along with the microchip is used to transmit and receive radio signals between the RFID chip and an RFID reader so that they can communicate.
3) Inlay - the inlay consists of the microchip connected to an antenna on a flexible substrate
4)Label/tag. The label or tag is the physical substrate that contains the inlay and allows the RFID technology to be attached to objects such as equipment and products.
What types of RFID labels are there?
Passive RFID labels - these labels do not have an internal power source and rely on the energy transmitted by the RFID reader to power the RFID chip and transmit data. When compared to active and semi-passive RFID labels these are lower cost and smaller but have a shorter reading range.
Active RFID Labels - these labels have their own power source, typically a battery, which allows them to transmit data over longer ranges and at higher frequencies compared to passive RFID labels.
Semi-passive (Battery-Assisted Passive) RFID Labels - these labels have a small battery to power certain functions, such as onboard sensors or extended read ranges, but still rely on the reader for communication.
The application requirements will determine what type of RFID label is most suitable.
What are RFID labels used for?
RFID labels are used across many industries for various applications but some of the main applications include the below:
Inventory Management - RFID labels are widely used in retail and logistics for tracking inventory, reducing stockouts, and improving supply chain visibility.
Asset Tracking - They are employed to track assets such as equipment, vehicles, and tools, enabling better utilization and maintenance.
Access Control - RFID labels are used for personnel identification and access control in buildings, parking lots, and events.
Transportation and Logistics - RFID labels help track shipments, containers, and pallets throughout the transportation process, enhancing security and efficiency.
Manufacturing - RFID labels are utilized for tracking work-in-progress, monitoring production processes, and managing inventory in manufacturing environments.
