The Fraunhofer Institute for Secure Information Technology (SIT) has developed the JAB code. This barcode consists of colored squares and can store more information on the same surface as its black and white counterparts. The Just Another Bar Code (JAB) is a development contract for the Federal Office of Information Security (BSI).

With traditional barcodes or QR codes, only a very small amount of data can be stored, which requires references to a web page or database. In this way, the user can often do nothing offline with the data. The JAB code simply stores the information itself. In drug packages, for example, a JAB code may contain the record.
Currently, JAB code developers recommend the use of eight colors, which is three times the data density of black and white codes. This is easy to read with the current smartphone cameras. With better cameras, more colors can be used and more data can be encoded.
The code is also interesting to increase security against the falsification of identity cards and other identity documents without a chip. For this purpose, the document content can be digitally signed and mapped in a JAB code. If you want to check the authenticity, you can do it with the camera of a smartphone.
The code of the JAB must be submitted to the standardization process of the German DIN Standardization Institute and be established as an international standard in accordance with ISO. The code itself is available as an open source under LGPL v2.1 license. Anyone who wishes can create and read JAB codes on www.Jabcode.org.
Microsoft has also experimented with colorful barcodes several years ago. The Microsoft tags were discontinued in 2015. Microsoft had introduced the format, which should represent an alternative to the already widespread QR codes, early 2009 and supported with its own services and online applications. By the end of 2011, the software was extended so that even traditional barcodes and QR codes could be read, as neither users nor retailers wanted to work with multiple systems.
