Most consumer devices emit Wi-Fi signals. Our world-class Wi-Fi sensors are able to pick up these signals and attach a unique, traceable identifier to each anonymous device using Randomized Media Access Control (MAC). This sets us apart in the industry. Using a combination of three or more sensors allows us to determine the XY location of the device, from which we can derive a rich set of behaviour analytics. As we have no knowledge of the individual end user, and do not collect or store any Personal Identifiable Information (PII), we are fully POPI, GDPR and CCPA compliant. This technology is ideal for cost-effectively determining behaviour patterns over large areas. It has the added advantage of tracking the reoccurrence of a device, which can usefully infer loyalty behaviour.
