Having your picture taken and placed on file is one thing. Doing bio analysis of your facial features and recording THAT is quite another. The difference between a finger print and just a photo of your hand.
They are called ‘biometric’ because they are ‘metric’ - a mathematical model of the face, not just a photo of the face. They take features of the face and insert them into an algorithm and out pops a number that completely represents the face. That number can be compared to a number for any other face, no matter what the position or orientation of the face, and determine if it is the same face.
