What is Apple Pay?

Apple pay allows you to securely accept and process payment from customers with iPhone 6 and iPhone 6+. User can buy physical goods and services in your app. Using Touch ID, users can authorize payments using credit and debit card payment that are stored on iPhone 6 and iPhone 6 plus.

How does Apple Pay transaction work?

Each time a transaction occurs, apple pay generates a token for the transaction. The token contains all the required information to do payment processing. The customer doesn’t have to enter their credit information because Apple Pay will pass the tokenized card information to our gateway.

What is the cost to use Apple Pay?

There is no cost to it. It is included with your USAePay account.
