As smartphones are popularized, the smart home technology that remotely controls home appliances at home is evolving. Until now, users who aren't familiar with smartphones had difficulties using smart appliances as they had to access the manufacturing company's server, go through user registration process and download an app. But lately, a domestic research team has developed a technology that enabled installation of apps and user registration at once by simply scanning the product's QR code.

These includes a technology that communicates with home appliances and controls temperature, standby power and gas via connection to mobile SNS.
