Creating QR codes in OpenBSD

[victorvas]

We wanted to send our users text messages in form of QR codes, for them to be able to scan those codes with smartphones.
At first we decided to use one of the web services for QR code generation, but then my friend Gunther found that you can create QR codes in OpenBSD by using a package named libqrencode.
terminal command:
qrencode -s 6 "Your text here!" -o code.png
where -s controls the size of the image (3 is default)

To read QR codes from the image you can use the package, called zbar.
terminal command:
zbarimg code.png

Nice. If this is a guide, do not hesitate to put it in the Guides section.

There are plenty of web servers that will create QR codes for you for free. But then you will share your information with third parties and trust them to do your computing for you.
I would rather do my own computing on my own machine.
I wouldn't call it a guide because of a very small amount of information I provided.
But it's worth mention on the forums.

I am OK with you.

I understand, thank you for mentionning it, I did not know it can be possible to create QR on OpenBSD.
Go on ahah!
