You can forget about the trade. Used filter cartridges cannot be used in any other machine. I had already dealt with this, with the result that the cartridges can no longer be reused.
The chips in the cartridges are described by the machine. Each chip has a unique ID that the Jura machine can remember. When the cartridge is used up, the cartridge is locked in the appropriate blocks. Each ml of water is stored on the chip. In addition, the switch-on cycles (if water was also used) are written to the chip.
The chips must also be specially addressed in order to be able to store data on them. They're easy to read, though. An Android Phone with the TagInfo App from NXP and you can read the chip. The code block 0 to 3 contains the unique ID. Block 8, the power-on cycles are stored. Block 10 to 1B is used for the flow rate. Maybe more (machine number). Block 1C to 1F I could change with a suitable RFID Writer at will, but before that not!
The following RFID Reader/Writer is installed in the vending machines: "https://fccid.io/2ADLV60900138/User-Manual/UserManual-pdf-2550467.pdf"
I gave up the chip story. Possibilities that would be there: to procure suitable blanks and replace the old ones. But also here I would think that they have to be prepared accordingly. In the new state the chip is already described. In addition, procurement is unlikely to be quite cheap. Thus no option mMn.
Another possibility would be to record and decode the communication between the Jura controller and the RFID reader/writer. A proprietary protocol such as the serial Jura connector, which has already been decrypted, could also be used here. Perhaps the same?
I will rely on an external solution here, without these RFID chips, but with complex additional hardware.
