I came across a site called zavee, and the site lets you use a credit card as a points reward card. I want to do the same but I don't understand how to do so. Even if I do obtain credit card numbers, how would I use that to track if the user buys from a specified place. A friend suggested that I should just use a system that compares the sales table of the location to the stored credit numbers to see if any match and then award point accordingly. But I think there's a better way, I just can't think of how. Would someone have some extra clues to help direct me?
