Samsung exec says iris scanners will come to mid-range phones, tech took 3 years of research
Mr. Koh revealed that Samsung invested over three years in its development, adding that iris scanning is the most secure ("in theory") out of all biometric systems. The company is thinking about letting third-party app developers use the scanner with an API, and is in talks with banks for the possibility of authorizing large transactions with it.
Moreover, continued cost cutting will eventually let iris scanners move to lower-tier smartphone models, boosting Android's often doubted security capabilities. This means future mid-range models by Samsung and other companies are eligible to receive the iris scanner module.
Competitor LG has been rumored to work on its own iris scanner solution with fellow Korean firm Irience. The iris scanner was widely expected to make its debut on the LG G5, but it looks like LG is holding it up for a future flagship phone. This could be the LG V20, which is supposed to appear by the end of Summer, running Android 7.0 Nougat.
