Apple’s FaceID is cool. Just as a finger print it scans the contours of your face. Maps it. And uses it as your ID.
Its very secured. So much so that the £30 per transaction limit on contactless payments.
FaceID is secured with your face map/print hence Apple can be sure it’s you. And as a result you can pay using Apple Pay without any restrictions.
What surprises me is the FaceID does not work in landscape mode. Sure it a map is a map irrespective of its orientation.
