A system for uniquely identifying wireless devices in a site comprising:

• a wireless access point for receiving data from a mobile device via a wireless network, the data including a plurality of different identifications for the mobile device;
• and
• a server in communication with the computer network for
• receiving a plurality of data packets from the wireless access point,
• detecting a plurality of different device identifications for a mobile device from the received data packets;
• storing in a database a data record for each of the plurality of different device identifications, the data record including each device identification, a first seen time stamp, a last seen timestamp, and number of detections for said each device identification;
• filtering the data stored in the database to determine repetitive or false device identifications in the plurality of different device identifications;
• eliminating the repetitive or false device identifications to obtain an accurate device identification for the mobile device;
• and
• using the accurate device identification to uniquely identify the mobile device associated with the accurate device identification.
