Abstract
Examples of techniques for encoding data in a 2D symbology are disclosed. In one example described herein, a computer-implemented method comprises capturing an image of the 2D symbology. The 2D symbology comprises a series of data symbols representing a binary string. Each of the data symbols comprises a line segment, and each data symbol in the series of data symbols are positioned in an end-to-end orientation starting at a starting indicator designated by a first symbol and ending at an ending indicator designated by a second symbol. The first symbol differs from the second symbol, and the series of data symbols comprise 0-bit symbols represented by a first data symbol and 1-bit symbols represented by a second data symbol. The method further comprises extracting the binary string from the 2D symbology by reading each of the data symbols between the starting indicator and the ending indicator.
