SYSTEM FOR MANAGING ENTRANCE/ATTENDANCE USING TOUCH SENSOR AND RF CARD READER, AND CONTROLLING METHOD THEREOF

PURPOSE: A system for managing entrance/attendance using a touch sensor and an RF(Radio Frequency) card reader, and a controlling method thereof are provided to save power consumption of the system by supplying the power to each circuit when a user starts the operation of a controller by using the touch sensor. CONSTITUTION: An RF card(100) includes the encrypted user information and communicates the wireless signal information with a receiver. The touch sensor(200) detects the contact from the user and generates a switching signal according to the detection result. The RF card reader(300) reads the user information included to the RF card(100), judges the opening/closing of a door by confirming the read information, generates the entrance information, and controls the door. An attendance management server(400) manages an attendance state of each user. An entrance controller(500) controls the opening/closing of the door according to a control signal or a remote control signal of the RF card reader(300). A central management server(600) keeps the door open on an emergency situation, and informs a manager of the user information and an entrance permission state.
