The minimum age to use Vipps is 15, but it is possible that in your Engage configuration a higher minimum age has been set. In this case, be aware that data coming in from Vipps won't be saved in Engage. To be able to use Vipps with Engage, the customer first need to sign up. This is done through what is technically known as a CIBA (Client Initiated Backchannel Authentication) and this process starts when the customer displays the identifying QR-code on the Vipps app on their phone in-store. The QR code Once the QR-code is scanned by the POS, the customer's mobile number is fetched and displayed. The customer will then be created as a contact in Engage through the integration between the POS and Engage. Vipps will never create the customer in Engage; that is done by the POS. Once the customer is created in Engage, a custom activity will trigger the onboarding flow that's been set up in Engage's automation tool: New contact registered automation Engage then triggers an app push to Vipps to ask the customer to share data with the merchant: The app push Information shared If the customer proceeds, they choose which consents (if any) they want to give.
