A read and write system for personal information cards employing a laser. Personal information is recorded on an information medium containing both visual images, such as a face image or fingerprint, and laser recorded data. The visual images are created on a piece of photographic material or eye readable laser recording material. The visual image material is adhered to a surface of a wallet-size card. A strip of laser recordable optical data storage material is also adhered to the card. After the strip is put on the card, a laser records personal information indicia on the strip in situ. The strip may be a reflective material of silver particles in a gelatin matrix, in which recording produces spots having a detectable difference in reflectivity. The card may be coated with a transparent protective laminate material. A laser reader and writer may be used in conjunction with the card and a device for moving the card relative to a laser beam for reading or writing information on the card. The visual images and laser recorded data may be related to a person.
