Abstract: An apparatus, method, and system that implements a Securities Tracking Management System (STMS) for providing an effective solution to clear, track, detect, manage, and alert various entities of invalid securities certificates. The STMS tracks securities certificates (particularly as they become invalid), and enables users to promptly query for invalid securities certificates without requiring the intervention of a transfer agent. In one embodiment, the STMS contains details of all invalid physical certificates that ever existed. The STMS may act as an early warning system for the clearing of physical certificates during the dematerialization process. Further, the STMS may also issue alerts of attempts to convert in securities certificates that are already marked as invalid in the STMS database. Further, the STMS allows the various entities involved in securities certificate trafficking to better track and manage expired certificates in an easier, more secure and transparent manner.
