RFID, or Radio Frequency Identification, is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information, which can be remotely read using RFID readers or scanners. RFID has numerous applications across various industries due to its ability to streamline processes, enhance security, and improve inventory management. Here's a breakdown of some key aspects of RFID:
RFID tags consist of a microchip and an antenna, enclosed in various materials such as plastic or paper. They come in different forms, including passive, active, and semi-passive. Passive tags rely on the reader's energy to transmit data, while active tags have their own power source, allowing for longer-range communication.
RFID readers, also known as interrogators, emit radio waves to communicate with RFID tags. They can read and write data to tags within their range.
Antennas are crucial for both RFID tags and readers, as they facilitate the transmission and reception of radio signals.
• When an RFID tag comes into the vicinity of an RFID reader, the reader emits radio waves that activate the tag.
• The tag then transmits its unique identifier and any associated data back to the reader.
• The reader captures this information and processes it, often sending it to a computer system for further analysis or action.
• RFID enables tracking and monitoring of goods throughout the supply chain, improving inventory visibility, reducing errors, and enhancing logistics efficiency.
• Many industries use RFID to track valuable assets such as equipment, vehicles, or tools, minimizing loss and optimizing asset utilization.
• RFID allows for automation of data capture processes, reducing the need for manual intervention and improving accuracy.
• By providing real-time visibility into inventory and assets, RFID helps streamline operations and reduce costs associated with misplaced items or stock-outs.
