It’s driven by two things - by the public perception that all bad guys fly coach (a la 911) and by governments seeking to expand the number of biometric means to enforce compliance of all sorts of things unrelated to travel. The irony is that many people who oppose a physical border wall on humanitarian grounds don’t seem to see the perils of virtual walls...such as when a visited country decides to share back my fingerprints it collected at the border with my home country despite legal protections against collecting my fingerprints when I’m inside/entering the home country OR any number of other applications that have nothing to do with border protection or everyday travel... unlike a physical barrier that can do nothing but it’s intended purpose. Sorry don’t mean to make this about borders but I’m trying to make a point that sometimes we use tech we end up creating entire new classes of problems worse than Ones we were trying to avoid... maybe the Amish have it right in this regard?
