Radio Frequency Identification (RFID) is a wireless technology used to automatically identify and track objects, people, or animals. An RFID system consists of RFID tags, readers, and a backend data management system. When a reader emits a radio signal, tags within its range respond with stored data—typically a unique identifier—which is captured and relayed to a host system for processing.

Unlike barcodes, RFID does not require line-of-sight, enabling non-contact, simultaneous reading of multiple tags for faster and more efficient data collection.

RFID tags contain an integrated circuit and antenna, which harvest energy from the reader’s signal to transmit digital data back. Readers then convert the radio signal into usable information for software platforms, supporting applications such as inventory management, logistics, access control, and analytics.

RFID technology provides scalable, reliable, and automated tracking solutions for a wide range of industries, improving efficiency, visibility, and operational control.
