To my knowledge there isn't anything native in JMP for creation of QR codes but you might be able to script it depending on your scripting skills. might be a starting point. Easier option is most likely to use some QR code API with JMP's New Http Request.

There are some good and bad choices for qr code generators on the web.

My favorite generator is the duckduckgo search engine, just type qr: https://example.com as the search.

The string can be anything; typically you want the https:// part as well.

The chrome browser can also share a qr code.

Chrome needs higher resolution. I think the dino in the middle needs extra error checking.

A bad generator will produce a code that links back to their site which uses a database to redirect to your site. They will help you collect statistics. And if you failed to understand how it works, they will let you know six weeks later that you'll need to pay to keep the link working (which will be cheaper than re-printing your material...)

This project was useful when I was researching: https://github.com/zxing/zxing

If you still want it in JSL, you can use HTTP Request to a restAPI with something like:
https://goqr.me/api/

The API has really only 2 endpoints and seems straight forward to use.

I call python and do it there using the qrcode module.

Thank you! I would like an offline version that doesnt connect to the web so I think this option would be the easiest/
