Rewards Points NOT based on sales

I need a shopping cart program that allows me to award rewards points to all paid members (with one click, certainly not individually) that they can then use in the store.  Is this program able to do this?  And while not wanting to be rude but I'm at wit's end searching, if this program doesn't do this, do you know of one that does?  It's an absolute necessity for my store.  Surely it exists, as all the credit cards, etc., use a system that isn't based on online sales but instead points that have been put into the customer's account.  Any help much appreciated.

Hi!  Thank you for replying so soon.

BTW - I doubt you will find this as a built in solution in any ecommerce cart (assigning points across the board / a group of customers). Reward points are usually a response to the customer taking some action and in the case of stores and credit cards that's almost invariably based on a transaction by the customer rather than an outside event.
