Here's a tidied up version of the Python code to generate the MRZ from the passport data. It also corrects a padding error.

My Dutch driver's licence has a single MRZ-like line across the bottom. It seems to encode the country and licence number but I can't make any sense of the rest of the line. Anyone have any leads?

I haven't found the docs for the Dutch version but this article shows the content of the MRZ of a French drivers license. They seem to match the Dutch ones as well.

Only partially. At least for my Dutch licence. It contains neither holder's last name nor end date.

It does start with D1NLD. Then a single digit which is not the checksum of the foregoing (using the passport checksum algorithm). Then the document number. Then some letters and numbers I can't make any sense of. It ends with a correct global checksum for all of the foregoing.

See the spec I mentioned. But here's an excerpt. https://upload.disroot.org/r/Y_vdT16A#cW4coNxPvTJN6b8InO5cHW...
