AIUI though this can be something of a false economy. Cash has processing fees too: you need to pay someone to count it, secure it, take it to the bank. Plus you need to deal with shrinkage. I can't find numbers now, but I remember seeing somewhere that suggested all of this was not all that much less than credit card processing fees. The only citation I can find now is that theft is something like $40 billion, falling most heavily on small businesses that don't pay for transport.
