Jesse Walker at reason covers the new wave in electronic payment transaction handling.
Seems that credit and debit card processing is wide open now and retailer costs are set to drop like a homesick brick.
In the Suki series, the backdrop at least, a key element to the 2030's is low friction transactions between buyers and sellers around the world. Like several other things, this is not the silver bullet that solves the problems of the world, just a major contributor.
I did imagine that easier communications and secure/cheep/free-ish transactions would result in more recreational travel and less labor migration. Most folks, just from my observations, wish they could make a great living where they grew up and travel to the more cosmopolitan places at their leisure.
