JAB Code Just Another Bar Code

JAB Code is a 2D color bar code, which can encode more data than traditional black/white codes.

JAB is a LPGL 2.1-licensed 4 or 8-color barcode spec with a C lib that uses those extra bits to encode more information than the typical black & white most barcodes support. There are a lot of use cases where extra bytes can really help out—such as sending a vCard with more than just name+email+tel or a multi-lingual vCard or a message that would normally require an always-on server to deliver the real message via a website.
