Apparatus and method for selectively engaging and securing an array of shelf dividers to a mounting device which is securable to a display shelf. In the first form a divider is characterized by a divider structure having an elongated vertical wall and elongated horizontal base that operates to divide, organize and support the displayed merchandise. A resilient latch located on the underside of the base of the divider structure selectively engages and secures the divider structure onto a mounting device comprising a receiving member running longitudinally along the length of the surface of the mounting device which is securable along the front edge of a display shelf. The latch and the receiving member each comprise reciprocating (i.e. complementary) protrusions to allow the cooperative engagement of the divider structure and mounting device, thus locking the divider member to and unlocking the divider member from the mounting device to permit the repositioning of the display as desired without necessitating removal of the merchandise from the display. In addition when the divider structure and mounting device are fully engaged, a second protrusion on the underside of the divider member cooperates with a flange or lip on the mounting device to prevent lateral movement of the divider structure and maintain the position of the divider perpendicular to the mounting device and the front edge of the shelf. In a second embodiment, the divider structure comprises a pusher track and a spring urged pusher assembly to automatically push merchandise to the front of the shelf. Another embodiment comprises a divider base without a vertical divider wall, and with or without a pusher track and spring urged pusher assembly, thus pushers and dividers can be used in various convenient combinations within a shelf management system.

A security document with optically excitable dyes for authenticity checking. Dyes are applied to or embedded in the security documents.
