Some states are gradually going cashless so they can reduce the incentive to commit crime or as a means of tackling bribery. It seems to me, that the idea of going cashless is not that entirely young..
"Not contented with this, he resolved to make a division of their movables too, that there might be no odious distinction or inequality left amongst them; but finding that it would be very dangerous to go about it openly, he took another course, and defeated their avarice by the following stratagem: he commanded that all gold and silver coin should be called in, and that only a sort of money made of iron should be current, a great weight and quantity of which was but very little worth; so that to lay up twenty or thirty pounds there was required a pretty large closet, and, to remove it, nothing less than a yoke of oxen. With the diffusion of this money, at once a number of vices were banished from Lacedaemon; for who would rob another of such a coin? Who would unjustly detain or take by force, or accept as a bribe, a thing which it was not easy to hide, nor a credit to have, nor indeed of any use to cut in pieces?"
