At least in the US 'virtual bank' seems more common. Either way: supported.

seeing that most us banks are going the way of all old things it might go back to direct bank. ;-) It sounds more like a phrase coined in Germany, GB it'll be phone banking or internet banking. However, wiki boasts its irish, anyway the phrase is irish since its not direct at all is it?
anyway, translation "direct bank" correct.

Now the entry has vanished from LEO completely: Siehe Wörterbuch: Direktbank
Why?
