RFID in Manufacturing

A Comprehensive Guide for RFID Application in the Industry

What is RFID?

RFID, or Radio Frequency Identification, is a technology that uses radio waves to identify and track objects. It works by encoding data onto RFID tags or smart labels, which can be read by readers using radio waves. The system consists of three core components: a tag or label containing an integrated circuit and an antenna, an interrogator or reader, and a communications interface that allows a computer to interpret and store the data. 

RFID can be used in manufacturing to track inventory, monitor the production process, and track assets. It has several advantages over existing asset tagging technologies like barcodes, as it can be read at a distance and without a clear line-of-sight to the tag. This allows the chip to be embedded in the surface of a product or in a discreet location.

How does RFID work in manufacturing?

RFID technology is used in manufacturing to automate information collection about the location and movement of stock and other components. The system consists of an RFID tag, reader, and antenna. The tag contains a microchip and an antenna that communicate with the reader via radio waves. As the tag passes through the reader’s electromagnetic field, it transmits its unique identifier to the reader, which then communicates the information to a central computer system. This provides real-time visibility into manufacturing operations, improves decision-making, and reduces costs. 

RFID technology is used in manufacturing to track inventory, monitor production processes, manage supply chain logistics, and reduce carrying costs. For example, tagging components, WIP, and finished products with RFID tags provides real-time traceability, while placing RFID tags on equipment helps locate lost or misplaced assets needed for production setup and execution.

What are the benefits of using RFID in manufacturing?

RFID technology has a significant impact on the manufacturing industry by improving efficiency, accuracy, and visibility in the manufacturing process. RFID tags can be used to track inventory, automate processes, and improve supply chain management. With RFID technology, manufacturers can reduce cycle count time, minimize manual tasks, and eliminate the “search regret” effect.

RFID can also help in identifying an item’s location within seconds, which can prevent the mixing of different styles or sizes of products. Moreover, RFID can reduce human error in manufacturing by analyzing the performance of individual employees and departments. RFID technology can be used in conjunction with clinical decision support systems, electronic health records, and hospital information systems in the healthcare industry.
