The real difference is that more transactions are cashless EFTPOS now.

I'm not precisely sure, but having worked in POS systems I can hazard a guess: systems which record a cumulative total of transactions, linked to the employee working the register. Someone will clock in, count the contents of the drawer (A), ring up some stuff over a shift (B), then cash up at the end (C); and A + B should equal C.

This still doesn't obviate the need to move cash around (which is also entered on the register), and some supermarkets still have pneumatic systems.
