How RFID Works

RFID technology uses radio waves to identify and track objects that are embedded with RFID tags. These tags consist of a microchip and an antenna, and they come in different forms, such as labels, stickers, or even embedded within products or packaging. The tags contain unique information about the item they are attached to, allowing for individual item tracking and identification.


The RFID system consists of three main components:

  1. RFID tags: These tags store the unique identification information and can be passive or active. Passive tags do not have a power source and rely on the energy emitted by RFID readers to communicate. Active tags have their own power source and can transmit information without relying on external readers.
  2. RFID readers: These devices emit radio waves and are responsible for detecting and reading information from RFID tags in their proximity. The readers can be fixed or handheld, depending on the application.
  3. RFID software and databases: The data collected by the RFID readers is processed and stored in software systems and databases. This information can then be used for various purposes, such as inventory management, supply chain optimization, and analytics.

When an RFID tag comes into the range of an RFID reader, it receives energy from the reader’s radio waves. This energy powers the microchip in the tag, which then sends the unique identification information back to the reader. The reader captures this information and forwards it to the RFID software system for processing and analysis.


Depending on the application, RFID systems can range from short-range to long-range. Short-range systems are commonly used in retail stores for applications such as inventory management and theft prevention. Long-range systems, on the other hand, are utilized in settings like warehouses and distribution centers for tracking large volumes of goods.
