Color Bit Code

What is Color Bit Code?

Concept

various shapes and colors of Color Bit Code sample

Color Bit Code is developed by B-Core Inc. exclusively, and is completely different from existing and conventional machine readable code. The products and parts which could not have those codes with previous technologies such as barcode and RFID because of various severe conditions can have an ID with Color Bit Code. It enormously contributes to the improvement of product control and work management in a wide range of fields such as manufacturing floor, inventory and logistics, leading to better quality of products and cost reduction. It finally gives us a lot of nonconventional possibilities.
We developed two kinds of code system as described below.
( All Color Bit Codes shown right are readable.)


※We renewed Color Bit Code demo video. In this video, you can see how to generate Color Bit Code by using "Tag Maker" and how to decode the code by using "Color Bit Reader".

1 Dimensional Color Bit Code

This code system consists of three color cells in chain.

1 dimensional Color Bit Code

Any three different colors can be used (The following figure is an example using RGB (Red, Green and Blue). The subsequent color has to be different from the previous color. Consequently, the next color is one of other two colors. For example, if the first color is blue, the next color is red or green. That means there are two kinds of color combination. Those two combinations are defined as “0 code” and “1 code” (1 cell = 1 bit). Digital camera such as CCD or CMOS sensor captures and decodes the codes by using image processing technology. The following figure is an example of Color Bit Code sequence.

1.5 Dimensional Color Bit Code

This code system consists of lines of three color cells configured in parallel.

The code is read by on-off action. Three colors create seven different color combinations and then septinary number by image processing.
1.5 dimensional Color Bit Code requires just a small area to mark but the information density is much higher compared with 1 dimensional Color Bit Code.
Because the marking method is very simple, a wide variety of applications are possible. For example, Color Bit Code can be marked on any (shape or) kind of materials because the marking method can be rough as shown right.
Also, Color Bit Code can be woven on a fabric tag by using 3 color strings
because of the simple code sequence.
