JAB Code

It was developed by Fraunhofer Institute for Secure Information Technology SIT [de].

The barcode is not subject to licensing and was submitted to ISO/IEC standardization as ISO/IEC 23634 expected to be approved at the beginning of 2021[4] and finalized in 2022.

[3] The software is open source and published under the LGPL v2.1 license.

This increases the chances the barcode can store an entire message, rather than just partial data with a reference to a full message somewhere else (such as a link to a website), which would eliminate the need for additional always-available infrastructure beyond the printed barcode itself.

It may be used to digitally sign encrypted digital versions of printed legal documents, contracts, certificates (e.g., diplomas, training), and medical prescriptions or to provide product authenticity assurance, increasing protection against counterfeits.
