nexo Retailer – Message Transport On Device

Using Broadcast intent

Messages sent to and from the Swedbank Pay Payment App are sent using broadcast intents.

For messages sent to the payment app the intent com.swedbankpay.payment.intent.TERMINAL_NEXO_MESSAGE is used, and for messages sent from the payment app to another app the intent com.swedbankpay.payment.intent.ECR_NEXO_MESSAGE is used.

The complete nexo SaleToPOIResponse or SaleToPOIRequest is placed as a byte array in the property extra of the intent.
