Labelling of product packages usually serves multiple purposes. Firstly, the label is human readable and helps to identify the package content. Secondly, the label is machine readable which is necessary to support automated work flow systems such as checkout counters of a supermarket by querying the currrent product prize. Until today, the machine readable label is usually a barcode containing a unique product number only. This is because the code capacity is limited to a certain number of characters. With the help of this number more data about the item can be obtained from a central data base. In many cases the data base, thus additional item information is not available.

Our color coding system is the most advanced and suitable system to create high density data storage labels. These labels are machine readable and can hold a substantial amount of information. The labels can be printed on any package or alternatively on adhesive labels which can be fixed to a package. Automated legibility ensures enhanced work flow based on additional data or even instructions implemented in the code.

This system is the only and first one of its kind in the world! It allows many current problems to be adressed. An important example is the fight against counterfeit. In this case, the code can hold substantial authenticity information making it possible to differentiate between copy and original. Another example is any product or personal identification which requires details to be available offline e.g. health information about patients in medical emergency environment. Howsoever, the coding system has the potential to solve many limitations and to enhance applications.
