By choosing to only have an EC card you’re making a deliberate choice to make your life difficult by using an incredibly obscure method of payment, no?
You can hardly expect those to work even in other EU countries, much less with an US based online business.
Almost everybody else in the world has a visa or a mastercard (or unionpay)
That was the standard normal card, I had ever since with that account - which is what all the people around me have - but it does work all across europe, in every shop I went.
Paypal is fine with it, so is coinbase. And every other online service I used.
(while backpacking international, I indeed had a credit card at that time)
So I recently only got a credit card(again), to be able to use Stripe. But most won't bother to do this, unless they have to.
"That’s because deep inside it’s secretly something like a mastercard maestro, no?"
Maybe? There is a maestro sign on it, but it is not a debit card.
But my point was, that I do not know, nor want to know all the details of banking communication. I want it to work.
It is a normal card around here and it does work in europe. So I never had the need to change, until now. So now I have a credit card, too and that is fine for me. But most other people here still don't, as most do not do international transactions.
So if Stripe wants to get into that market, they likely will have to adopt. No one here would offer stripe on their webshop - with only a few being able to use it.
Apparently I do have an debit card and apparently something at Stripe had changed, since when I tried it some months ago, because now it all worked(without me changing anything) and I did not even needed my credit card. Who knows.
