You mean like a temporary credit card number valid for a small period of time or valid for a specific vendor?

We have those (at least in America), and have for many years. Services like "ShopSafe".

They also create many hassles and headaches. Can make returns difficult, validation difficult (please show the card used, what, it's a virtual card?), and the rigor may not be great (reoccurring charges on "invalidated" numbers, etc).

Yes - exactly. And with a specified amount so I am safeguarded from anu surprises.

I have never seen a service like that - so (I think) it is mainly on your side of the pond.

My Swedish bank also supports it so it's not unheard of in Europe either
