3d code

In addition to the one-dimensional 1D code (1D), the barcode or bar code, there are a wide variety of 2D codes and 3D codes. While 2D codes encode their information in two dimensions

and thus have a significantly higher information density compared to bar codes, 3D codes use three dimensions.

3D codes use color or depth information as a third dimension. If a 2D code is also equipped with, for example, color information with 8 bits, then it offers 256 additional variation possibilities. A 3D code with depth information is a hologram in which the information can also be depth modulated. The information density is many times higher than that of a 2D code with colour information. An example of a 3D code is the High Capacity Color Barcode (HCCB).
