A machine readable binary code which is dynamically variable in size, format and density of information is provided. The binary code is formed as a matrix having a perimeter and data contained therein. The perimeter is provided with density indicia for indicating the density of data contained within the matrix. The perimeter is also provided with size indicia for indicating the size of the matrix. By utilizing the density indicia and size indicia, a scanning device is able to calculate the size and information density of the binary code.

A method for determining the size and density of a dynamically variable machine optically readable binary code forming a matrix having a perimeter having a first side and a second side, the first side and second side each being formed of a solid line of equal lengths and intersecting at a first corn

A method for determining the size and density of a dynamically variable machine optically readable binary code forming a matrix having a perimeter having a first side and a second side, the first side and second side each being formed of a solid line of equal lengths and intersecting at a first corner and a third side of the perimeter and a fourth side of the perimeter, each being formed of an identical broken line pattern formed of alternating dark areas and light areas, the third side and the fourth side intersecting at a second corner corresponding to the density of data contained within the matrix comprising the steps of: scanning the binary code with an optical scanner to convert the matrix and the surrounding area of the matrix to a sequence of electronic impulses, wherein the binary code and visual code are located in a visual field; converting the signal of electronic impulses into a series of electronic data bits corresponding to the scanned image; forming a bit mapped image of the matrix; locating and determining the length of the first and second sides of the perimeter; and determining the product of the number of light areas and dark areas of the third side and the number of light areas and dark areas of the fourth side.
