Well, they still pay a fee, it’s just reduced.

They primarily don’t deal with cash because cash is a pain. It needs to be physically taken to a bank and protected from theft by both staff and random robbers with guns, it needs to be counted all the time, and you need to maintain the right denominations to make change.

I have reservations about businesses getting rid of cash, especially if they’re turning away people who don’t have alternative ways to pay, but I certainly understand why they do it.

It’s also always awkward when a coffee shop is like 95% credit, and you try to hand them cash and they look at you like you’re Rip Van Winkle.

Merchants aren't going cash only to sell your data, they're doing it because it's expensive to handle cash and makes their taxes a whole lot more troublesome too.

Huh, I thought accepting legal tender was a federal rule, I guess not. Looks like a salad variety of regulations that vary by state and city.

I mean, cash is also expensive in its own way. It has to be handled and insured, coins may need to be rolled before being taken to the bank, a register is a mechanical device to power and maintain, petty theft by employees is a concern.

It's not really that hard to see why a business charging $5-20 per transaction from people who all have phones and credit cards anyway might choose not to accept cash.
