It's good for security, it's more convenient than police doing police work.
Until it's not. Until it's hacked or abused as powerful mechanisms commonly are.
Hacking is a concern in both but the bigger issue is potential for abuse of power.
In the case of border checks the target is by necessity someone that isn't a citizen. This means that:
1. We generally afford them less safeguards than citizens so it creates less precedent (both legal and in terms of overton window)
2. The potential for abuse is ultimately less because a traveler on a short term visa is unlikely to still be in the country / unable to leave if a hostile government comes to power and intends to abuse the data
Also fingerprints and a picture are significantly less invasive than pervasive video surveillance in public spaces
And let's be honest, that's not why "some" people are against them.
It only works if the "intellence-driven security" is being developed in good faith.
History shows that the main question with government and data collection is not "what X makes life easier for citizens" but "who collects/uses X and for what purpose". In the happy case, this may be all well and peachy. The case people rightfully worry about is not that case.
Well, there is a third camp. Israeli-style bio-social profiling of 100% of travelers.
That really makes travel awful !
Maybe this resonates in the American case where cops are notoriously undertrained and over-violent, but I gotta say it sounds extremely dystopian to me. All-power computerized control isn’t “intelligence”.
It’s also a false dichotomy. You can have lots of automation with humans in the loop. Humans can use automation to be faster and this is common.
