> Many credit card providers, at least in the US, let their customers generate single-purpose or short-term card numbers, for when you don’t trust the merchant, or need to let someone else use your card.

My experience with using short-term card numbers has been validation failure in the webforms where I try to use them.

I use them all the time, never had one refused. The web site front end validation can only check the number with the Luhn algorithm — number looks valid. Actual validation and accept/decline gets done by the payment processor.
