Systems and methods for integrating member identifiers with point-of-sale systems

A system, comprising:

• a merchant backend;
• and
• a merchant point of sale device in communication with the merchant backend;
• wherein:
• the merchant backend is configured to create a customer account for a customer;
• the merchant backend is configured to assign a member identifier to the customer, wherein the member identifier uniquely identifies the customer;
• the merchant point of sale device is configured to receive payment card information from a payment instrument and to provide the payment card information to the merchant backend;
• the merchant backend is configured to generate a value from at least some of the payment card information;
• the merchant backend is configured to map the value to the member identifier;
• the merchant point of sale device is configured to receive as part of a pending transaction received payment card information from the payment instrument and to provide the received payment card information to the merchant backend;
• the merchant backend is configured to generate a received value from at least some of the received payment card information;
• the merchant backend is configured to retrieve the member identifier from the mapping;
• the merchant backend is configured to apply a member benefit to the pending transaction;
• and
• the merchant backend is configured to execute the pending transaction.

A non-transitory computer readable storage medium, including instructions stored thereon, which when read and executed by one or more computer processors, cause the one or more computer processors to perform steps comprising:

• creating a customer account for a customer;
• assigning a member identifier to the customer, wherein the member identifier uniquely identifies the customer;
• receiving payment card information for a payment instrument;
• generating a value from at least some of the payment card information;
• mapping the value to the member identifier;
• receiving, as part of a pending transaction, received payment card information for the payment instrument from a merchant point of sale device;
• generating a received value from at least some of the received payment card information;
• retrieving the member identifier from the mapping;
• applying a member benefit to the pending transaction;
• and
• executing the pending transaction.
