A two-dimensional, high-density, damage-tolerant printed code suitable for encoding multiple biometrics and text for positive off-line identity verification comprises a horizontal header section; a vertical header section; a start pattern; a left row address pattern; an encoded data portion; a right two address pattern; and stop pattern. The horizontal header section encodes the number of bit areas in a transverse row of the encoded data portion; and the vertical header section encodes the vertical height of each bit area. The start and stop patterns of the code demarcate the lateral extent of the code (i.e., the beginning and end) from the adjacent quiet zone. Information is encoded into the ended information portion in bit areas that may be printed or blank. The information is encoded sequentially in the information portion from the top of the encoded information portion along each transverse row of bit areas to the next row of bit areas until the end of the encoded information portion. Error correction is applied to subunits of information from the encoded information portion by dividing the user messages and applying error correction to subunits of the user message. The two-dimensional, high-density, damage-tolerant printed code is suitable for printed on a conventionally sized ISO cord or other papers used in verifying identity. An ISO-sized cord or other identity paper bearing a two-dimensional, high-density, damage-tolerant printed code encoding multiple biometrics, e.g., encoded image likeness and multiple finger print templates, maybe used with an off-line integrated positive identity verification apparatus that is capable of decoding the image and fingerprint samples taken from an individual whose identity is sought to be verified.
