Yawn Nobody cares about counterfeit cash. The technological gap b/w counterfeiters and national mints has continuously expanded. Today, even most countries have given up trying to update their technology, and have started buying their bills from a small number of printers (i.e. Giesecke & Devrient). More importantly, only a tiny fraction of money in circulation is actually held in cash. Today, most countries could declare all cash worthless overnight and it wouldn't have a major effect on the economy. All the infrastructure to move to electronic payments is already in place, and trade could continue unharmed.
