Clankers found me one study [1] that suggests total handling costs may actually be this bad, but are highly business dependent e.g. restaurants are worse than grocery stores

I'm just seeing what looks like an attempt to sell me a PDF.
What actually is the source of such costs? The cashier still has to be paid even if the customer is using a card. Presumably there isn't anywhere near that much theft from registers, or people messing up giving change?
Clank deeper, please. You gave us content marketing from the electronic payment industry:
