Important: The Tap to Pay on iPhone feature is not yet available. These documents are an early draft and are subject to change.
Use our Tap to Pay on iPhone™ SDK to allow merchants to take payments using Apple’s Tap to Pay on iPhone feature in your iOS™ applications. Tap on Pay on iPhone uses the near-field communication (NFC) reader on a merchant’s iPhone to read the payment details on a customer’s payment card and send the information securely to our gateway to process the payment.
