Will selfies become the primary mode of authentication?

This week's Question: MasterCard has tested facial biometrics for payment authentication and has now begun rolling out its MasterCard Identity Check, or "selfie pay," to a greater number of users. The biometric authentication app is available throughout Europe, including Austria, Belgium, the Czech Republic, Denmark, Finland, Germany, Hungary, the Netherlands, Norway, Spain, Sweden, and the UK. MasterCard’s Identity Check app also supports fingerprint biometrics, offering customers a choice of authenticating a mobile payment with either their face or finger at the point of purchase.
