ABSTRACT:
An identification system utilizes a plastic housing which is appropriately sized to hold either a key or a coin as well as an information sheet on which the user may place selected indicia referring to the key or to himself. Each embodiment utilizes a living hinge closure attachment to secure the key or coin and information sheet within the housing. Utilizing the housing as the indicia for identifying the key minimizes the excess material and connections thereby simplifying the identification and storage problem, yet because the use of the housing with the key slightly increases the size of the key head, it provides a slightly greater moment arm for turning the key in a lock and gives a slightly larger gripping surface to be employed when so turning the key. These factors are significant when dealing with children and with elderly people who may not have the physical strength and dexterity required for some small headed keys. When my device is used with coins inserted it is envisioned that the user would at all times have in his housing attached to his key information about himself and sufficient change to operate a pay telephone.
