Of course you can rationalize that 3% is a reasonable cost and approximately a wash compared to the expense of dealing with cash. But if you're a small coffe house, and sell a $3.00 coffee, and are paying a typical 2.9% + $0.30 per charge, that $0.30 is ten percent of your sale. That's a huge cost.

Transaction fees need to come way down for plastic to beat cash on small sales.
