The portuguese ATM network operator provides this for free (its called mbnet btw). You can even set expiry times and value limit, it's the best thing to use when paying for stuff online. Want to buy a 9€ game? Just create a 10€ card and use it.

Yup, I use this all the time. They even, recently, added support to multi-use cards with bigger expire dates.

I wonder how hard would it be to make a startup like this.
