Just one more step on the road to abolishing cash altogether.
Governments don't like cash. Well, technically, governments which want to control their population don't like cash, 'ccause they cannot track it, and they wanna know where all the cash is, . . . because, . . . because, . . . well, just because.
Lots of countries impose restrictions on cash-transactions and impose fines if they are violated. Lots of countries limit how much cash can be moved across a border too. Almost every country requires notification by its banks of transactions above a specified value.
And when Central Banks institute near-zero-interest-rates or even negative-interest-rates [umm, . . . like right now] there's no way they can collect their interest on cash deposits.

So Governments look forward to the day when all financial transactions are digital, . . . and, f'rinstance, the slot machine will report every "penny" of every transaction to the Government as it happens.
And won't that be a fine day !
