UM808 series is the UHF read/write module developed by our company. It is designed with Impinj's special UHF RFID chip R2000, which has stable card reading function. It supports EPCglobal UHF Class 1 Gen 2 / ISO 18000-6C, ISO 18000-6B protocols, and the unique I-Serch multi-tag recognition algorithm provides the highest recognition efficiency in the industry. It also utilizes a dual CPU architecture design, which greatly improves overall performance. The low voltage and low power consumption design is an excellent choice for embedded project applications. Can be widely used in manufacturing and supply chain, digital warehouse management, commercial retail, asset management, etc. management, neighborhood management, and access control systems.
