PrimerQRCodeScope manages payment methods that display a QR code for the user to scan (e.g., PromptPay, Xfers). The SDK automatically polls for completion after the QR code is displayed.

Customization

PropertyTypeDescription
screenQRCodeScreenComponent?Full screen replacement. Signature: (any PrimerQRCodeScope) -> any View
This scope inherits start(), cancel(), onBack(), presentationContext, and dismissalMechanism from PrimerPaymentMethodScope. QR code scopes do not use submit() — the payment completes when the user scans the QR code in their banking app.
