Abstract: The system of the invention provides a credit card size CD containing eye readable and machine readable personal and medical data. The eye readable information on the CD provides a medical care provider with an overview of a cardholder's medical condition and emergency and insurance contact information. The machine readable information encoded on the CD provides significantly more additional information about the individual than the eye readable information. The CD is encoded with programs to receive, organize, store, protect, transmit and display the machine readable data. The CD is approximately the size of a standard credit card and can be read in any standard personal computer CD reader such as a CD-ROM.
