There are more people who cover their face (e.g. Muslim women wearing burkas) than people who don't have fingerprints. I wish they had both TouchID and FaceID.
You have to decide which type of biometrics to use when you choose your model, but that's fine for a lot of cases (such as those who wear burkas or those who have no fingerprints).
Hopefully the return period gives people enough time to be sure they've made the right choice.
