Global tech giants have been seeking to feature iris scanners in their mobile devices as the scanners are considered to provide tougher security than fingerprints.

LG Electronics has been carrying out various efforts to tap deeper into biometric security technologies, a source familiar with the issue said.

Still, an LG Electronics' office in Seoul said the company does not have an official statement on the rumor, saying it cannot provide details on the smartphones to be released next year.

LG Electronics' G6 and V30 smartphones launched this year only supported fingerprint screening.

Samsung Electronics first included an iris scanner in its Galaxy Note 7 phablet released last year.

Although the device was short-lived due to battery problems, Samsung has since incorporated iris-scanner technology into its other flagship smartphones. (Yonhap)
