This I would like to know

Currently as far as i know, only Sampo Visa electron cards seem to work online. Don't know about Nordea etc.
I have one and i have never had a problem ordering stuff online. It works like a typical credit card. It works even if it's not listed.

I asked from my bank (Osuuspankki) about it and it seems that I have to activate "verified by Visa" service first. Then it shouldn't be a problem I think
