RFID is a technology that uses radio waves to identify objects. It communicates with tags through radio signals and can quickly read data without physical contact. An RFID system consists of three main components: the tag, the reader, and the backend management system. Tag: An RFID tag is an electronic label attached to an item, containing a microchip and an antenna. Tags can be passive (without a power source) or active (with a battery). Passive tags obtain energy from the radio signals sent by the reader, while active tags can send signals autonomously due to their built-in battery. Reader: An RFID reader transmits radio signals to communicate with the tags and receives signals reflected by the tags. The reader decodes the data from the tag and sends it to the backend management system. Backend Management System: The backend system analyzes, stores, and processes the data collected by the reader. This system can be integrated with enterprise business systems such as ERP (Enterprise Resource Planning) and WMS (Warehouse Management Systems) to update inventory information in real-time. The application of RFID technology can greatly improve warehouse management efficiency and accuracy, thereby helping enterprises achieve zero-error inventory management. 2. Working Principle of RFID in Warehouse Management In warehouse management, the RFID system simplifies every aspect of inventory management through automated data collection and processing. The specific workflow is as follows: 1. Goods Receipt When goods arrive at the warehouse, RFID tags are attached to each item. These tags store relevant information such as product IDs, quantities, production dates, and suppliers. Once this data is entered into the backend system, it is automatically linked to the corresponding inventory record. When the goods enter the warehouse, RFID readers positioned at entry points automatically scan the tags and transmit the data to the backend system. The system automatically updates the inventory records, ensuring that the inventory quantity in the system matches the actual goods quantity. Due to the high efficiency of RFID technology, the entire process requires no human intervention, reducing errors during the receiving process. 2. Inventory Management RFID systems monitor the location and status of each item in real-time by placing readers throughout the warehouse. Each item’s RFID tag is automatically scanned as it passes by a reader. With multiple strategically placed readers, such as on shelves, storage locations, and conveyors, RFID technology helps enterprises gather real-time inventory data, reducing errors caused by manual operations. Additionally, RFID systems can assist warehouse managers in predicting inventory needs through data analysis. By analyzing historical inbound and outbound data, the system can identify high-demand products and slow-moving items, enabling precise inventory allocation and management. 3.
