Question

How would consumers who traditionally pay using cash potentially benefit from an interchange fee cap?

Answer 1

@angle maybe you know something about this? :S

Answer 2

This would be referring to the fact that the merchants are charged by credit card companies about 2-5% of their sale in order to swipe credit cards.

By paying in cash, you could potentially bargain with the merchant and receive a discount, as most listed prices a higher due to this credit card fee.
