At the International Security Conference in Las Vegas last week, Seoul Commtech, a division of Samsung, showed off the company’s EZON SHS-1210 digital door lock. Instead of using physical buttons for the individual numbers, the SHS-1210 features a touch sensitive display integrated into special black tempered glass. So the numbers are only visible after the user has pressed a control button which activates a backlight. For added security the SHS-1210 is also made from aluminum alloy to enhance its strength, has built-in fire detection and is even able to withstand electric shocks up to 30,000 volts.
