Abstract
A system and method for preventing push-out theft includes a network of electronic devices that are collectively operable in either a 'safe restart' mode' or in an 'operational' mode. The network is installed in a shopping area and prevents shopping cart removal from the area when in the 'operational' mode. It does this by initially issuing egress permits to every shopping cart. The network then selectively removes egress permits when a shopping cart enters a selected section of the shopping area. Another egress permit is issued when the shopping cart successfully passes a cashier location. Otherwise, a sentry beacon will disable a shopping cart with no egress permit, before it can leave the shopping area. The network defaults to a permit issuing mode whenever a component of the system becomes inoperable.
