LF RFID Handheld Reader is a portable rugged terminal embedded with low-frequency RFID reading modules, specialized for short-range identification of 125KHz and 134.2KHz tags. Different from long-distance UHF readers, it features stable short-distance sensing performance and strong anti-interference capability, which works well near metal, water and dense materials without signal attenuation. Most devices run Android OS and carry IP65 rugged housing to resist dust, splashes and accidental drops for long-term field use. Supporting real-time data transmission via Wi-Fi, 4G and Bluetooth, it stores tag information offline when networks are unavailable and synchronizes records to background management systems later. Common applicable tags include animal ear tags, personnel access control cards, employee ID tags and industrial low-frequency asset labels. Main scenarios cover livestock tracking, staff attendance verification, factory personnel access management, vehicle inspection and small valuable asset checking. It ensures reliable identification in complex environments where high-frequency or UHF equipment fails, providing accurate, stable data collection solutions for breeding, construction site management and factory internal supervision.
