1. An apparatus for associating a participant identifier with an unassociated radio frequency (RF) location tag, the apparatus comprising at least one processor, and at least one non-transitory memory including computer program code, wherein the at least one non-transitory memory and the computer program code are configured, with the at least one processor, to cause the apparatus to: receive tag derived data originating from an unassociated RF location tag; determine unassociated tag location data for the unassociated RF location tag based on the received tag derived data; receive second tag derived data originating from a plurality of associated RF location tags; determine associated tag location data for the plurality of associated RF location tags based on the received second tag derived data; determine tag proximity location data for each of the plurality of associated RF location tags by comparing the unassociated tag location data to the associated tag location data; determine a constrained set of associated RF location tags from the plurality of associated RF location tags based on determining, by the processor, whether the tag proximity location data for each of the plurality of associated RF location tags satisfies a proximity radius; determine a participant identifier for each associated RF location tag of the constrained set of associated RF location tags; in a circumstance where two or more unique participant identifiers are determined from the constrained set of associated RF location tags, determine whether one of the two or more unique participant identifiers is associated with a malfunctioning RF location tag; in a circumstance where one of the two or more unique participant identifiers is determined to be associated with the malfunctioning RF location tag, output a tag participant correlator for associating the one of the two or more unique participant identifiers with the unassociated RF location tag.
