USA are checking fingerprint and face foreigners at border. USA requires a "biometric" passport, which is not so "biometric" as it is only a passport with a RFID memory chip that electronically stores the printed data, and so the face. It will be possible in the future to store fingerprint, iris, but this is not mandatory at the moment.

Lessons to learn from the Clear kiosk program's demise (Caroline Cooper)
(In a nutshell, but have a look at the original article): The Clear program was supposed to make life easier for frequent travelers. Members would simply swipe their Clear card at the program's airport kiosk, which would then read their biometric data (fingerprint and iris scans) and submit approval for the attending Clear agent to take them through a special, expedited security line. But the company never was able to properly implement that model.
The technology that they chose did not meet any of the TSA requirements, meaning that Clear travelers that got to the security checkpoint still needed to take their laptop out, still needed to remove their shoes, because you couldn't integrate Clear into a TSA line.
