SCPReaderPaymentInteractionDelegate

Objective-C

@protocol SCPReaderPaymentInteractionDelegate <NSObject>

Swift

protocol ReaderPaymentInteractionDelegate : NSObjectProtocol

Implement this protocol to handle payment interactions for mobile and tap to pay readers that require your application to display UI and provide a response before the payment can continue.

The provided delegate must be retained by your application until the reader disconnects.


                    
                    
                    -reader:didRequestInteraction:

This method is called when a payment interaction requires a response from your application.

Inspect the concrete SCPPaymentInteraction subclass to determine which UI to display and use its completion method to continue the payment.
