The S8 will apparently blend together fingerprint, iris and facial detection to verify a user for payment services — and Samsung is apparently already working with banks to get the feature adopted. The company's flagship phones have offered facial recognition to unlock for years, and it's gotten much better at detecting faces as the Galaxy series has matured.
As Bloomberg notes, Apple is approaching facial recognition too. Although it doesn't form any software features in existing iPhones, the company has picked up several facial recognition developers in the last few years. The Galaxy S8 will give Samsung the chance to make up for last year's blunders, and get ahead of a highly-anticipated iPhone that will mark 10 years of Apple's smartphone series. The big Samsung event is in a few weeks -- we won't have wait long.
