PSU Authentication with the ASPSP using browser based redirection for a PIS request.

This enables a PSU to authenticate with their ASPSP while using a TPP for the PIS service, using the same web based authentication method which they use when accessing the ASPSP web channel directly.

This model works when the PSU is consuming the PIS service on a device that does not have the ASPSP app, or the PSU does not have the ASPSP mobile app.

Wireframes

To demonstrate web based redirection we have used one variation of PIS journey (Sec  Single Domestic Payments – a/c selection @ PISP) as an example, where the ASPSP receives all the details of the payment order from the PISP.

This redirection flow applies to other variations of PIS journeys covered in detail under section Payment Initiation Services (PIS).

What the research says

“Research amongst consumers has shown that 29% of participants actively prefer a browser based PIS journey for a single domestic payment, whilst 32% prefer an app based journey. Those preferring a browser based journey refer to security and ease to explain their choice. Those preferring the app based alternative select it because they deem it easier than the web based experience, with fewer mentioning security.”
