RFID Reader (Radio Frequency Identification Reader)

An RFID reader is a device that identifies and reads data stored on RFID tags using radio waves. When an RFID tag is placed near the reader, data is wirelessly transmitted and displayed on the screen. The information on the tag, pre-written in digital format, is processed and converted into readable content by the device.

RFID readers are available in short-range and long-range models and are widely used in applications such as automated identification, access control, payment systems, inventory tracking, warehouse management, robotics, navigation, and jewelry authentication.

RFID Reader: Main Operation
