A payment integrated loyalty system including a point of sale terminal comprising a card reader, a communication subsystem configured to wirelessly communicate with a payment instrument, and configured to communicate over a network with at least a first and second server. The payment integrated loyalty system includes a processor in communication with the communication subsystem and card reader, configured to receive, through the communication subsystem, a payment instrument identifier associated with the payment instrument, and obtain a fingerprint based on one-way encrypting the payment instrument identifier. The processor is further configured to receive, from the first server via the communication subsystem, a loyalty balance associated with the fingerprint and to complete the financial transaction based on an updated amount based on the loyalty balance.
