Gatekeeping the exit: retail loss prevention technology
2026-06-26 , Prime Dome

We've all done it, you walk out of the store and the exit portals start beeping.... So you just keep walking. Tag-based retail anti-theft systems have been with us for decades, and there are several distinct generations of technology in use. Some of them rely on interesting physics, others use state of the art RFID technology for integrating into point of sale and supply chain systems. All of them are, almost universally, hated and ignored. We'll learn about magnetostriction, visibility networks, and shopping carts that form mesh network swarms while they wait in the parking lot.


This talk will cover a timeline of retail loss prevention technology, and then focus on the current generation of mesh networking, IP-integrated systems with surveillance and marketing implications. We'll also discuss the business and technology reasons that loss prevention technology is widely installed but very inconsistently used, and efforts to apply similar technology to problems like armory and nuclear material management.
