Title: Biometric time and attendance - PowerPoint PPT Presentation

Description: KJ249 Mine underground personnel the biometric time and attendance integrated technical complexity content of rf identification technology, using dual-frequency point the size of wave frequency to attain reliable full duplex wireless data communication, sub-station equipment, control equipment, communication interface and RFID logo card using flameproof and intrinsically safe design, contribute to play distance, identification associated with a adjustment employee time, identify the "blind spot", signal penetrating power, security, high-performance, non-electromagnetic pollution on your body, environmental adaptability can identify more than easy underground network connection and digital biometric time and attendance transmission performance advantages, this new information collection, storage, transmission and processing technology, would be the coal mine monitoring, control, and monitoring and tracking management play a very important role. – PowerPoint PPT presentation
