The Discreet Pants Fly Checker was made with this in mind. Basically, this is a device that lets you discreetly check in public whether or not your pants fly is up. By pressing a button located in the watch pocket of your pants, a small pager motor alerts you to whether or not the zipper is up. Basically, the zipper of the pants was enhanced with two strands of conductive thread which form a complete circuit when bridged. A small circuit board with a battery, button and motor attached then snaps into the watch pocket. Finally, when the button is pressed, and the zipper is closed, the circuit is completed and the motor vibrates.
