Introduction
The high-performance UHF 16-port RFID module SIMX400, leverages IMPINJ’s E710/E510/E310chips to deliver adjustable output power from 5dBm to 33dBm (configurable up to 30dBm). Capable of reading tags beyond 12 meters (dependent on antenna gain and tag size), it integrates an advanced multi-tag recognition algorithm for rapid inventorying of both stationary and moving objects at speeds exceeding hundreds of tags per second. With superior anti-interference design and carrier cancellation technology, SIMX400 ensures stable operation in challenging environments such as logistics warehouses, manufacturing assembly lines, and automated patrol systems. Its versatile configuration modes cater to diverse applications including retail inventory management, medical equipment tracking, and smart cabinet integration, making it a top-tier choice for industrial-grade RFID deployment.

Application
- Filing Cabinets and Tool Cabinets Management:
In enterprises or institutions, strict permission control and records are often required for accessing important documents and tools. By integrating the RFID SIM X400 reader module into filing cabinets and tool cabinets, automated asset identification and management can be achieved. Employees only need to swipe their cards or enter passwords to open the cabinet doors, and the system will automatically record information such as the time, personnel, and items taken for each opening, thereby improving security and reducing human errors. Additionally, this module supports batch reading functions, making inventory work more efficient and fast, especially suitable for scenarios with frequent borrowing and returning of tool management and confidential document storage.
- Application of Intelligent Shelves:
The intelligent shelf is an important part of the intelligent transformation of the modern retail industry. Based on collected data, the system can also analyze consumer purchasing behaviors, push personalized promotional information for them, optimize store layouts, and then increase sales volume and service quality. This technology is not only suitable for retail places such as supermarkets and convenience stores but also shows great potential in fields like pharmaceutical warehousing.
- Operation of Vending Machines:
With the development of the unmanned retail concept, more and more vending machines have begun to adopt advanced technological means to improve user experience. For example, vending machines equipped with built-in RFID SIM X400 reader modules can complete transaction processes by scanning QR codes or other payment vouchers on consumers’ mobile phones, which greatly improves checkout speed without manual intervention throughout the whole process.
