Samsung to launch fingerprint-based mobile payment system in South Korea by the end of the month

With its new biometric authentication system, Samsung is expanding past smartphone-mounted fingerprint sensors, as the company has plans to integrate its password-free authentication system in numerous other product categories such vehicles, smart homes and other IoT-based devices. In the past, multiple Samsung patents surfaced online hinting that the company is looking into iris-scanning systems as well, and this recent announcement only strengthens our beliefs that Samsung is betting big on alternative authentication systems.
The Galaxy S5 was the first Samsung smartphone to use a fingerprint sensor, and while performance was a concern with the S5, the manufacturer significantly improved its fingerprint recognition technology this year with the Galaxy S6 and the Galaxy S6 edge.
