Apple to get 15 cents for every $100 worth of transactions carried out via Apple Pay
That translates into a 0.15% fee, multiple times less than the 2.75% services like Square will charge you for a similar operation.
Apple's 0.15% fee is much lower than that of competing servicesInterestingly, Apple has managed to negotiate lower rates than participating banks usually accept for credit card transactions. How is this possible? Turns out that the banks are betting on Apple Pay being an enabler that would help them reach a much larger scale, getting transactions that have not been passing through their credit cards.
It’s worth noting that Apple Pay has gotten huge support by retail chains like Starbucks, McDonalds, and Walgreens to name a few, all of which will support the system. Some popular stores, however, will not accept the new system, and Wal-Mart and Best Buy are the two most prominent ones.
