This will never work across the general public, though. Have y'all ever watched people trying to do returns with codes on their phones? It's not even a stereotypical boomer thing, it's all ages and both genders. A huge chunk of the population can't even handle doing returns with a code on their phone. The biggest hurdle the ruling class would have trying to implement this for everyone buying anything is the ruling class being hilariously out of touch with the general public. Even when it comes to things like grocery stores that have spent a ton of money creating huge self checkout areas, there is still always a long line of people waiting to checkout with the 2 cashiers that are left. All of this dystopian techy future shit is very unpopular with the masses. But the ultra nerd sitting in his luxury office playing with his google glasses doesn't get that. He's totally out of touch with what the people actually want. He thinks everyone should be as excited as he is about his niche interests and in his unchecked narcissism he assumes that it'll all be embraced by most people. And then there are thousands of retards just like him involved, thinking the general population gives 2 fucks about the super cool convenient new technology, so then their marketing is even more retarded and falls flat. Accessing one's home and vehicle with fingerprints has been available for several years yet almost nobody uses that tech because nobody actually wants it, there's no real market for it, when it first was pitched several years ago people went "oh great so criminals will try to cut my fingers off" and the whole idea was DOA. Watch and see what happens if they try to force everyone off of cash, would be an absolute shitshow.
