Abstract: An apparatus for providing secure and unique identification of individuals includes a device for electromagnetically recording and storing data indicative of a specific individual. The device receives and stores data in various fields. A system for use in tracking and identifying individuals includes an electromagnetic identification device that has a plurality of data fields, each being adapted to receive identifying signals; a writer for encoding the signals into the appropriate data fields; a controller for receiving signals uniquely identifying an individual and storing the signals in a master database; and a reader adapted to interrogate the unique individual identification signals stored on the electromagnetic identification apparatus and for comparing corresponding individual identification signals with signals received from the electromagnetic identification apparatus and generating an alarm signal if a discrepancy exists.

Abstract: A tracking system for use in identifying individuals of a group, each of the individuals having an associated data set indicative of the identity of those individuals, includes an electromagnetic identification apparatus configured with each of the individuals for providing an electromagnetic identification signal indicative of the content data set of that apparatus; a writer for use in encoding the electromagnetic identification signals with signals indicative of the individual onto the electromagnetic identification apparatus; a controller for receiving the encoded signals and for storing the encoded signals in a master database storage apparatus; and a reader remotely positioned from the controller and configured for communicating with the electromagnetic identification apparatus and receiving the encoded signals therefrom corresponding to the content data signal set, the reader also for providing the controller with signals indicative of the same.
