Gatekeeper Systems, founded in 2010 and based in the United States, operates within the Business Services industry, specifically focusing on security products and services. The company addresses the growing challenge of pushout theft in retail environments, a tactic where shoplifters exit stores with unpaid merchandise. Their primary solution, the Purchek® system, employs Smartwheel® technology to disable shopping carts if an attempt is made to leave the store without completing a purchase. This innovative approach not only deters theft but also enhances the shopping experience by minimizing disruptions. Gatekeeper Systems has published several case studies highlighting the seasonal increase in pushout theft, particularly during the holiday season, and the financial impact on retailers. These documents emphasize the need for effective, non-confrontational security measures that protect both customers and staff. The company's insights into retail theft dynamics and the development of behavior-based solutions reflect its commitment to enhancing security in retail settings while promoting a safer shopping environment.
