Here is a great example for all, Trustly ONLY use open banking SEPA to power their service. Have a look at what they are IPO'ing at below And guess what .......no cards
Imagine a hybrid multi-rail open banking SEPA, SWIFT and 70% of cards (ISX have all except Visa). Also Remember, Visa in the regulated sector is very small % due to its brand risk-averse policies they have.
