readCardForExternalTransaction - Nayax Developer Portal

The readCardForExternalTransaction method reads card data from the device so that the transaction can be authorized by an external processor instead of the built-in payment engine. Once the card is read, pass the returned pinpadCardDataId to updatePinpadTransactionStatus to report the outcome of the external authorization back to the device.
