Abstract
A bracelet assembly for carrying identification information. The bracelet assembly has an elongated flexible band with fastening means for fastening the band in a closed loop fashion around a patient's limb. There is a transparent portion on the flexible band through which the user can read the identification information. A permanently deformable layer is interposed between the transparent portion and a base layer. The base layer and permanently deformable layer are of contrasting colors. The permanently deformable layer is deformed by lines of force applied by mechanical pressure means such as a typewriter or credit card imprinter which deforms the deformable layer along the lines of force which correspond to the identification information. This renders the base layer visible through both the transparent portion and the permanently deformable layer along the lines of pressure.
