alt Hacker NewsVisa and Mastercard don't, but right now cash more or less does. If the state has a monopoly on digital payments, and can thus mass surveil all digital payments without any scrutiny, the state has a huge incentive to disincentivize or bar the use of cash. Then all it takes is a bad actor to come into power and abuse the system.
No more so than with visa or mastercard, who already hand over data whenever, and hand it over to a foreign government on demand too.
This fear of government services is toxic americanism.
