Understanding RFID in Logistics
What Does RFID Stand For?
The full form of RFID is Radio-Frequency Identification. It employs radio waves to identify and track information stored on tags that are attached to objects — without requiring that the tags be scanned in a direct line of sight.
What is RFID?
RFID is a technology that employs radio waves to communicate data between a reader and an RFID tag. An RFID tag contains electronically stored information, which can be wirelessly transmitted to a reader or scanner. This technology has been widely adopted across various industries, including logistics and warehousing, due to its versatility and efficiency.
How Does RFID in Logistics Work?
RFID in logistics works by the tag and reader communicating continuously through radio waves. Here’s how step by step:
- Tagging Items: RFID tags with a unique identification code are placed on the products or assets.
- Capturing the Data: RFID readers broadcast radio waves that power up tags within their proximity, allowing them to be automatically scanned — even if they’re in boxes or on the move.
- Transmission & Processing: The tag transmits information back to the reader, which forwards it to the central system or warehouse management application.
- Tracking & Improvement: The data is continuously updated in real time and they use it to follow their in-wandering warehouse teams, beginning inventory movement, using assets, making faster decisions.
Manual scanning is eliminated and human errors are reduced, which means logistics operations can be done quickly and accurately with the help of RFID.
