What is RFID? Definition, Working, and Benefits Explained


 RFID (Radio Frequency Identification) is one of the most impactful technologies for modern businesses. To fully understand its value, it’s important to know the definition of RFID and how it works.

RFID is a system that uses electromagnetic fields to identify and track tags attached to objects. The tag contains a microchip and antenna that communicate with an RFID reader. When the reader sends out a signal, the tag responds with stored data. This data is then processed by a software system for analysis and decision-making.

Unlike barcodes, RFID doesn’t require direct line-of-sight scanning and can read multiple items at once. This makes it faster, more efficient, and less prone to errors.

In practical use, RFID works in industries like retail (for stock management), logistics (for shipment tracking), healthcare (for patient safety), and manufacturing (for production optimization). Its ability to provide real-time insights makes RFID a necessity in 2025.
