Face ID 支持apple pay 3万个点验证
Apple has ditched Touch ID for Face ID in its new iPhone X, enabling users to authenticate themselves - including for Apple Pay and apps that support the feature - simply by looking at their handsets.
To make an instore payment, users double click the button on the side of the phone, look at it and then hold it against the contactless reader.
Face ID works by projecting 30,000 invisible infrared dots when the user looks at the phone, checking the pattern against a stored image in real time. Data is stored on the handset.
