ABSTRACT:
An internally-illuminated medical data card in a credit card format containing a summary of the medical history of the bearer germane to his existing medical condition. The card, which is of laminated construction, includes a core panel formed by front and rear plastic sections having light-transmitting properties, a metallized layer functioning as a double-faced mirror being sandwiched therebetween. Nested in the respective faces of the core sections are front and rear film transparencies containing medical data in a directly legible scale, the combined data affording the required summary. The long edges and one end of each core section are in a concave formation to define reflective convex terminations whereby light entering the remaining flat end is transmitted through the section is reflected by the convex terminations and by the mirror to provide multiple internal reflection, causing the light to illuminate the transparencies to enhance their readability.
