I think the more relevant functionality is called in France "e-carte bleue" : https://fr.wikipedia.org/wiki/Paiement_sur_Internet#La_e-car... (Sorry, only in French).

You generate a fake card number, this number is linked with an expiration date AND a maximal amount that can be charged.

The quality of the service varies between banks though, I remember my previous bank who forced me to go over a sketchy-looking website and use a Flash applet to generate the card...

AFAIK it's not possible to create a card with a monthly chargeable maximum amount, only to set the total amount for the card's lifetime, which limits the interest of the use for recurring payments.
