Residents in societies, condominiums & gated communities are instantly notified of visitor information in their mobile Biizlo app by the Biizlo Shield app operated by the trained security staff stationed at the entry gates who capture following information, viz., name, photo, image, mobile no., wing no. or building name/no., flat no. or apartment no. being visited, purpose of visit, vehicle # and other visitor information. This instantly sends phone notification to relevant residents in their Biizlo app wherever they are. Residents can, then, authorize and manage this activity prior to visitors reaching them.
