There is no denying that biometric measures offer a more convenient and secure way to authenticate identification for payments than traditional methods, and the shift towards digital payments will no doubt further push payments authentications to that direction. After all, it sure beats signatures. However, biometric authentication is no failproof either — just consider the fact that you can easily change your password if it gets leaked vs. it’d be impossible to change your palm print/iris/voice pitch if they get hacked. The ideal way forward for payment authentication would be a hybrid of biometric authentications and local device-based one-off tokenization, which, in turn, means platform owners with digital payment solutions (like Apple and Google) could gain more leverage.
