The provider is Wise - an "e-money" institution. I've been using them for well over a decade. They are very good. Never had any issues until recently - a service I was interested in uses Stripe to "verify" the card before charging. Stripe rejected all Wise cards - physical and digital. I had to use my legacy bank's debit card. Problem is, the legacy bank charges outrageous forex fees and has an awful spread on top of it, so if I can't use Wise card after "verification", I will have to give up on the service. I asked them what could be done and they just said they use Stripe and that's it.
