It allows users to access entrance using pass code, smart pass, or “RF TAG”. Unlike existing hand-operated door locks, our product is combined with IT technology so that consumer convenience (automatic and manual, voice function, etc.) and security features can be enhanced. Safety level was also increased by applying the specialized technologies such as anti-panic, anti-shock and anti-fire functions. Moreover, a card sensor was relocated a bit higher so that access to the sensor became easier. We also separated pass code touch line in order to reduce error rate of entering the pass code, while creating a unique line design.
