If you have not lived in Russia, in some cities bureaucrats, cashiers, bank clerks are not necessary for 90% of mundane operations (which gives people more time to attend to the rest 10% of operations). We simply have best online banking and online government services. In some supermarkets there are even self-checkout machines ... and they just work without sophisticated tracking and 10x cameras and tags. It just works on honour system and just regular surveillance. Especially I was shocked when I found them in a lame-ass supermarket in my home town. Of course there were people to monitor the process and help, but it was 1-2 people per 10 self-checkout machines.
