QR code generator recommendation (free and reliable, please)

[carcar1996]

I’ve been looking into using a QR code for something a bit more personal. I recently developed some health issues, and I’d feel better having my emergency contacts and key health details on a small QR code attached to my keychain. I read in several places that some generators advertise as free, but then disable the code and you need to pay a subscription. And I’ve seen a few people on other forums having a good experience with Uniqode, and it seems solid, so I’m wondering if anyone here has actually tried it. My main concern is finding a free generator that’s still reliable. If I’m relying on this in an emergency, the last thing I want is a code that doesn’t scan. I might mess around with it for lighter stuff too (I'm thinking about sharing Wi-Fi access at home), but for the health info, I need it to just work.

QR codes just store encoded data, could be text, an image, a url. It's an open specification, there are free applications that will generate them for you.

ShareAsQR (A lightweight app for QR code generation from text or sharing from other apps.)

Tons of free open source options, off the top of my head:

Libreoffice writer: Insert -> OLE object -> QR and barcode
Inkscape: Extensions -> Render -> Barcode -> QR Code

For the connoisseurs, a cli tool in linux: qrencode
