Systems and methods for providing low-latency access to cardholder location data and determining merchant locations and types

A system comprising:

• one or more processors;
• and
• a memory in communication with the one or more processors and storing instructions that, when executed by the one or more processors, are configured to cause the system to:
• receive, at a first computing device, updated location information from a second computing device, the second computing device associated with an account holder;
• determine, at the first computing device, whether location information associated with the account holder exists at the first computing device;
• responsive to determining that location information associated with the account holder does not exist at the first computing device:
• generate an entry in a first data group for storing information associated with the account holder;
• and
• add information associated with the account holder to the entry in the first data group;
• responsive to determining that location information associated with the account holder does exist at the first computing device and that the location information at the first computing device does not match the updated location information:
• update the location information at the first computing device to include the updated location information;
• and
• determine one or more output locations for the updated location information;
• responsive to determining that the location information at the first computing device and the updated location information are matching location information, determine one or more output locations for the matching location information;
• and
• output the updated location information and/or the matching location information to a central storage.
