FaceID

Apple’s FaceID is cool. Just as a fingerprint, it scans the contours of your face. Maps it and uses it as your password.

It’s very secured. So much so that the £30 per transaction limit on contactless payments.

FaceID creates a scan/map of the contours of your face; hence, Apple can be sure it’s you; it is intelligent enough to distinguish between a picture and a live face. And as a result, you can pay using Apple Pay without any restrictions.

What surprises me is that FaceID does not work in landscape mode. Sure it is a map; and a map is a map, irrespective of its orientation.
