MasterCard, one of the largest credit card processing firms in the world, is testing out an application that allows people to confirm their identity and authenticate online transactions via a facial scan.Instead of several ways to authorize a transaction such as using fingerprint, MasterCard is going to let you take a selfie without having to manually enter passwords or security codes."The new generation, which is into selfies... I think they'll find it cool," the firm's security expert Ajay Bhalla told CNN.When taking a selfie, the user has to blink so that someone would not just hold a photo of someone else to trick the app and fool the system. The app will also support fingerprint scanning.A security expert; however, told the BBC facial recognition should be complemented with extra layers of security as Google also tried facial recognition on Android phones and encountered a lot of problems.The feature is still in the early stages of development, and MasterCard plans to let 500 cardholders test it before everyone else.
