"Virtual" and/or "prepaid" credit Cards

Just curious, why the big desire for the "virtual" cards?

Are you guys afraid of fraud?

Never been too concerned since I only use cards online with low available lines in case they get lifted. I have 2 cap 1 accounts and they raised my credit on the low one a while back. I called them and asked them to lower it back down since its the one I use online.

They obliged and increased the other one by the same amount

They just don't get it.
