An increasing number of Korean companies are involved in Beacon business, which is considered to be one of the services of the Internet of Things (IoT). A Beacon is a wireless sensor using Bluetooth technology. When Beacon transmitters are installed in specific places like stores or concert halls, Beacon can detect signals from mobile devices that support Bluetooth. By doing so, information about products or services is automatically offered to people through a related app installed on the device. It is a contactless method, and therefore it is cited as a method that can replace Near Field Communication (NFC), which can only be utilized by directly tagging objects.
