A lot of information for Tassimo T-Disk barcodes. Gives indication for further hacking attempts. Some additional links (also found on the page itself):

• OneOfSix made some of the original decoding attemps and explains some of his journey.
• wiki.mbirth.de contains a lot of good knowledge, updated through 2016 and with further reading and might be the closest to actual decoding of the codes.
• spreadsheet of barcode experiments super interesting experiments with barcodes, someone went through and changed one bit at a time and observed the results

All of this information together with further tests could actually make Tassimo capsule machines somewhat useful again, perhaps even for non-capsule uses. (I am imagining 'refillable' capsules in which you just pour your ground coffee, add the correct lid and use it like a normal coffee machine; or even just using it as a tiny water kettle)
