A 3-D code, also known as a three-dimensional code, represents a further development of the conventional 2-D code. While a 2-D code encodes information in two dimensions, the 3-D code enables an additional third dimension through the use of colors.

The color components of the 3-D code help increase data capacity and coding accuracy. By introducing colors, different information can be encoded in one code, allowing a larger amount of data to be represented in a compact form. This enables efficient acquisition and processing of the coded information.

The areas of application of the 3-D code are diverse. In industry and logistics, for example, it is used to mark products, components or pallets. By using color codes, information such as product type, serial number, date of manufacture or storage location can be encoded. This facilitates the traceability, identification and inventory management of goods.

The 3-D code is also used in marketing and advertising. The three-dimensional representation allows companies to create interactive and visually appealing content. Customers can scan the code with their smartphone and get access to additional information, videos, discounts or product reviews. The 3-D code thus opens up new possibilities for personalized and experience-oriented marketing campaigns.

In addition, the 3-D code is also used in security technology. By using color codes in conjunction with other security features, counterfeiting or tampering with products or documents can be better detected.

Overall, the 3-D code offers an extended coding possibility for extensive data due to its three-dimensional representation and the use of colors. It is used in various areas such as industry, logistics, marketing and security technology. The 3-D code enables efficient capture, processing and use of information for various purposes.
