Abstract: A customer frequency, analysis and reward system has multiple alternative components and allows for input of customer identification through use of a smart card, biometric input device, or a preexisitng identification, such as a credit card, government-issued id, or checking account. A customer interacts with the system initially at a data collection point-of-sale (POS) device at a retail outlet. Data is periodically collected from the retail site to a data warehouse, where various types of analysis may be performed. A customer can interact with the system using an internet interface, thus reducing costs of ownership.
