That's a lot of speculation.
When you open a shop, handling the money is ALWAYS a cost of doing business. Banks charge fees, credit and debit card processing has a fee, each transaction has to be accounted for, taxes paid, books keep current. As a store you must price your products to pay for the overheads of all kinds, and still make something.
I find it hard to believe that Apple is pricing their system significantly higher than any of the existing systems.
In any case, here in America we are desperately in need of a new system. Our present credit card system is highly insecure. Just look at the terrible hacking scandals in the last year or two.
We also have fallen so far behind the rest of the world, traveling is substantially harder for Americans these days because other countries have moved to Chip and PIN setup for over a decade now.
And we lose money from tourists too. I was recently in O'Hare airport and they had actually put hand written signs on the credit card machines at the duty free shops warning foreign customers that Chip and PIN could not be accepted. That's tourists from 84 countries who will now not be able to shop at an American business because we are so far behind the times.
So no, I'm not going to cry tears for shops that refuse to move with the times. It's time to move away from writing checks and using plastic cards with VHS tape glued to them. Time to embrace the future, and figure out a way to make it work that is equitable for all concerned.
