PosiCode

The PosiCode symbology was developed for use in direct marking processes, where it is difficult to control the width of the bars in a barcode. It is a continuous, "position based" one-dimensional symbology: all bars are the same width, and the encoded data is determined by the position of the bars relative to one another.

ClosedThe Character Set

The standard version can encode all 8-bit values.

The limited version supports the following characters:

ClosedThe Symbology Structure

Each encoded character is comprised of three bars and three spaces. Each bar is approximately the same width, while the distance between bars (i.e. each space) is a multiple of the bar width. Distance between bar centers vary from 2-9 units for PosiCode A and 3-10 units for PosiCode B.

All PosiCode barcodes end with a mandatory check character, which contains six bars and six spaces, followed by a stop character of four bars and three spaces.
