Baryons’ store location tracker is used by retailers’ staff when they visit different stores. The person visiting the store, can take a photograph of the store once inside the store and upload it to the portal. The photograph with the GPS location of the store is uploaded by our app. The system then validates the store photo and the known GPS location of the store. Only when the current GPS and known GPS location of the store match, does the system acknowledge the upload by the visiting person and register his visit.
