A customer relationship management system wirelessly detects presence and identity of a customer when the customer enters a business establishment. The system captures a visit pattern of the customer based on communication from the wireless device. A relevant marketing message for the customer is determined based on the customer's presence, visit pattern, identity, and location. The marketing message is delivered directly to a wireless device carried to the customer upon a subsequent entry of the customer to the business establishment. Responses of the customer (e.g., purchasing patterns, etc.) are stored for subsequent use in presenting relevant offers.
