This is only going to become more common. Companies are implementing checks using similar services (a) to prevent employment scams (where the person who interviews is not the person who works; usually the latter is a low-paid offshore individual) and (b) basic security authentication. It won’t be long before this sort of biometric validation starts showing up to authenticate users on regular websites and similar services, if it hasn’t already. I think the last one I had to do was to authenticate when activating a bank card.
