Abstract: Systems and methods may identify customers based on payment and point-of-sale (POS) data collected from a merchant POS system. In one aspect, the systems and methods receive the POS data at a secure server. Customer identities may be determined based on a randomly-generated token associated with a payment identifier. Customer payment data and third-party reservation data may be matched with the POS data and the customer identities at the secure server based on ticket information to generate consumer metrics. In some embodiments, the systems and methods generate the consumer metrics for display on a client electronic device for a merchant/retailer.
