Payment by Points

Hi!

I got aware of Isotope Commerce by a friend. I am looking for a possibility of an eshop which can handle payment by points - ie users get credited points to their account and can then use their points to buy goods from the eshop. (like worldshop.eu for example - or any other mileage Shop).
Is this supported by Isotope or is there a Plugin for it?

Thanks for any hint,
Christian
