JAB Code is a color two-dimensional matrix symbology whose basic symbols are made of colorful square modules arranged in either square or rectangle grids. JAB Code has two types of basic symbols, named as master symbol and slave symbol. A JAB Code contains one master symbol and optionally multiple slave symbols. Master symbol contains four finder patterns located at the corners of the symbol, while slave symbol contains no finder pattern. A slave symbol can be docked to a master symbol or another docked slave symbol in either horizontal or vertical direction. JAB Code can encode from small to large amount of data correlated to user-specified percentages of error correction.
