Is there a QR-Code reader application for Mac OS X? I'm using Mac OS X 10.6 and an iSight.
I just discovered QR Journal, which works fine for me. The latest version requires OS X 10.8/10.9 but there is a legacy version available which works with 10.6.
Now desktop users with an iSight (or iSight compatible) camera can read QR codes. Found a QR code in a magazine or catalog? Simply hold up to the iSight camera to scan, store and browse to. Received a QR code in an email? Just drag it into QR Journal to read it.
There is an open source command line tool named ZBar. It takes a photo as an argument and extracts the information out of any QRCode that it detects in the image.
The open source project QR-Reader-Mac provides an Applescript script that acts as a wrapper to
zbar. You can create a shortcut to the script for processing QRCodes or create a service, as explained below. The script will automatically open the URL contained within the QRCode in your default browser.
Step by step
ZBar can be easily installed with Homebrew:
brew install zbar
To install QR-Reader-Mac:
Open the QR-Reader-Mac GitHub project page, select Code and download the project as a ZIP file:
Double click the ZIP file to extract it.
Double click the workflow you want to install. The following Pop-UP should appear:
Confirm by pressing
Open System Preferences and add a shortcut to the open_QRCode service under Keyboard > Shortcuts > Services > General:
(Important: Note that QR-Reader-Mac expects to find the executable 'zbarimg' in
/usr/local/bin/zbarimg, which is the standard path Homebrew will install it.)
Copy to Clipboard
QRCode2Clipboard.workflow can be used to extract the content of the QR-Codes into the Clipboard. It can be installed in the same way as the
No free app that I'm aware of, but for a few dollars/euro you can download QuickMark from the Mac App Store, here's the link
The app that worked flawlessly in my macOS Big Sur is this: https://apps.apple.com/ie/app/code-reader-qr-scanner/id1225393668
I tried QR Journal, as suggested by others here, but for some reason the camera didn't detect the QR code so I ended up finding the other app.
Note: I am in no way affiliated with either of these apps.
It's not free, but LensOCR is exactly what I needed. I use it solely for the barcode/QR scanning feature.
It allows me to screenshot a portion of my screen containing a barcode or QR code and instantly saves the result to the clipboard. I know OP asked for free... but when you find the right app that you will use a ton the $11.99 one-time cost is justified in my book.
Note: The original question implies the use of a webcam for scanning. The app I recommended above does not use the webcam at all. It just interprets screenshot content.
