FaceID sensors can easily do fingerprint scans without contact and no worries about moisture on your fingers. So if they want they could offer additional security for banking.
The interesting thing is that this has to work right out the box for apps that use TouchID for Apple Pay. It’s possible that touchID will be just holding your hand in front of your phone, and the way I have seen this work you don’t have to be completely still.
I’m not sure why nobody is considering contactless fingerprint scans, one system even read fingerprints accurately from many feet away.
