摘要：
A system for controlling shopping carts usage in the vicinity of a parking lot, the system comprising: a device that repeatedly transmits a lock command from a directional antenna (282), said directional antenna mounted above ground and angled downward to create a lock zone (286) in which shopping cart use is restricted, said lock zone encompassing an exit area associated with the parking lot; and a plurality of shopping carts, each shopping cart comprising a brake mechanism, and comprising an RF communication circuit that is responsive to the lock command by activating the brake mechanism.
