3D codes have been researched for over 15 years. Even 2D codes can store short texts or other information. However, codes that use color as a third dimension are far superior in this respect. They open up numerous fields of application and raise technical, economic and ethical questions. According to a press release, the JAB Code of the Fraunhofer Institute for Secure Information Technology SIT – JAB stands for “Just Another Barcode” – is on its way to becoming an international ISO standard. “Job references, training certificates and wills, but also proof of authenticity for products can be secured with JAB Code. (Press release Fraunhofer SIT, 26 June 2020) Furthermore, longer texts can be stored. Already in 2010 Oliver Bendel has published a book with QR codes from which haikus could be read offline. In the same and the following year he scientifically dealt with 2D and 3D codes. A longer article on the topic from 2011 can be found here – the teaser and the link are included in in this 3D code, which can be scanned via www.jabcode.org. A 2D code also manages a text like that, but already has an enormous complexity. Waldemar Berchtold from Fraunhofer SIT explains: “With eight colours, readability is robust, with the smartphones available on the market. Whereas with more than eight colours, reliable readability with older smartphones cannot be guaranteed across the board.” More about the Fraunhofer Institute project at www.sit.fraunhofer.de/de/presse/details/news-article/show/bunter-barcode-wird-iso-standard/.
