Today I had trouble paying online with my virtual Mastercard. In two German shops I couldn't pay by card. Both times I was led to an external site by Mastercard for the payment. Both times my card got declined with the comment it is blocked.
After a bit of research I found there is a thing called Identity Check by Mastercard, that is supposed to make online shopping safer.
Apparently one must first register for one's Mastercard. But I can't find anything by searching the knowledge base.
Am I on the right track here? Does anybody know something I missed? Or am I just lost with paying online in Germany right now?
Thank you all in advance.
