A unique identifier is given to the customers of a primary merchant. The unique identifier suggests to the customer various secondary merchants within or around the community. Incentives at the secondary merchants can also be offered through use of the unique identifier. Purchases made by the customer at the secondary merchant using the unique identifier are recorded in a database for marketing analysis and possible remuneration to the primary merchant. The unique identifier can be returned to the primary merchant for reuse with a different customer.
