Abstract

The disclosed system allows a credit or charge card issuer to provide its card members with a list of merchants, products, services, vacation destinations or other offerings that might be of interest based on the purchases of similar card members. In one instance, this process looks at all card members that made purchases at a merchant and then it identifies all other merchants in the same category where those card members also made purchases. The associated merchants are ranked based on largest number of shared card members and the top results may be shared with card members or merchants in order to enhance promotions, card use and marketing.
