Overview
Radio Frequency Identification (RFID) is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tag, a radio receiver, and a transmitter, and can be used to track inventory goods, among other applications. Unlike barcodes, RFID tags do not need to be within the line of sight of the reader and can be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC) and is used in many industries. The use of RFID technology can improve efficiency and reduce costs.
🎵 Origins & History
Origins paragraph — The history of RFID technology is not well-documented, but it is known that RFID systems consist of a tag, a radio receiver, and a transmitter. Today, RFID is used in a wide range of applications, from inventory tracking to payment systems, and is supported by industry leaders.
⚙️ How It Works
How it works — An RFID system consists of a tag, a radio receiver, and a transmitter. The tag, also known as a transponder, is a small device that stores and transmits data. The receiver, also known as a reader, is a device that sends out electromagnetic waves to communicate with the tag. The transmitter is a device that sends out the electromagnetic waves to power the tag. When the tag receives the electromagnetic waves, it transmits the stored data back to the receiver. This process is known as backscattering. RFID systems can be classified into two main categories: passive and active. Passive RFID systems use tags that are powered by the electromagnetic waves sent by the reader, while active RFID systems use tags that are powered by a battery. Active tags can be read at a greater range than passive tags and are often used in applications where the tag needs to be read from a distance.
