Finally, there is a non-trivial cost to securely storing and
transporting cash to the bank for deposit and to keeping enough
coins and smaller notes on hand to make change.

Those are the elements which make up the "1%" (rather than "0%")
quoted as the typical cost of accepting cash, versus the "2%" for
cards.

In fact this misses that banks /charge/ businesses that pay in large
quantities of cash, especially coin.

sigh that's where much of the 1% comes from.
