Hi Anders

Have a look at model https://standards.openbanking.org.uk/customer-experience-guidelines/authentication-methods/decoupled/model-d-psu-with-a-tpp-account/latest/

Once the TPP/Merchant (could be a petrol station or smart home device) has setup a PSU account and bound to the PSU bank account (e.g. via an initial one time re-direct), it is entirely up to them how they initiate a payment - could be voice, number plate recognition, etc. The PSU then gets a push notification in their mobile bank app to authenticate. 

I think there are some incentives (maybe not regulatory) for banks to adopt CIBA and models like this, and this is possibly the most realistic option in the medium term

1. Based on an international standard
2. Supported now by several vendors which the banks use
3. A relatively small extra build for banks who are already FAPI compliant
4. Still allows for PSD2/RTS requirements of SCA and Dynamic Linking
5. At least the CMA9 banks are all happy with this from a security POV

Thanx Chris for the prompt response!

I must admit that I'm not particularly versed in CIBA but have hands-on experience with Open Banking APIs.

My target is not related to any regulations but rather how to create something bigger like this: https://empsa.org/
Is that even possible without a standardized mobile client?

The proposed solution also supports Gas station payments although few (if any) Open Banking APIs are currently ready for this task.
It would be interesting to know how this is intended to work with the current Open Banking scheme.
https://app.swaggerhub.com/apis/SWIFT-API/payment-preauthorisation/0.2.1
does not shed much light on that topic.

Last but not least the proposed solution stick to the established payment card notion using SVG for visual representation.
Here is a sample: https://www.linkedin.com/feed/update/urn:li:activity:6591608038912729088/

I'm open for working with the OBIE in case there is any interest in this.

Kind regards,
Anders Rundgren

This solves some use cases but, as you state, is notb as good as Apple Pay, especially in a Point of Sale scenario. It would however work for an app-app (e.g. online purchase via a mobile app) scenario.

However, no ASPSPs are implementing this yet, as it has not been specifically required by any regulators at this time.
