Abstract: Systems and methods for implementing a rewards program for registered customers of a business make use of a central computer server and a database that is in communication with the central computer server and that stores data about the registered customers. Multiple mobile devices associated with the various registered customers communicate with the central computer server via a software application running on the mobile device, and a subset of the data from the database is thereby communicated to each of the multiple mobile devices from the central computer server. A query of the data about the registered customers is then initiated from the central computer server and communicated to each of the multiple mobile devices via the software application running on each of the multiple mobile devices, with a result of the query being processed on each of the multiple mobile devices then communicated back to the central computer server.
