With the Nexus system, we already have this in Canada. When flying, i stick a card in a terminal, it scans my irises, asks a few questions, and prints out a receipt to give to the official upon exiting, no questions. Super easy. Similar with Global Entry in the US. That one scans your passport and finger prints and takes a picture to present to the official who then asks a few questions...because America.
