I'd probably get hate for this or whatever, but things like this is why it's inevitable that businesses and governments will eventually force cryptocurrencies on people, because then purchases/expenses/bills and anything else can be tracked fully across the spectrum.
I'm not for it, don't want it, but I can't help myself but to see that as the future, as fraud ramps up even more, gets cheaper and businesses feel they have no other way to combat it except adding more tracking everywhere, something blockchains and cryptocurrencies excel at, for better or worse.
Alternatively, companies will just go back to corporate cards with very strict vendor rules. When vendor rules are not enough, they will go back to extremely tight per diem and simply not care of the expense was strictly real or not. I can't see any advantage to using a whole new currency and exchange that every vendor in the world is now going to have to support for this to be useful vs these simple measures.
So it does seem like the companies themselves do worry about if what you spend it on is legit or not, it's almost the entire purpose of the article unless I misunderstand something?
