Once the code is visible completely, please wait for the website to scan it.Otherwise, the website won’t be able to provide any results. While scanning the QR code, please make sure all edges are visible.There, you must find the correct file, and the website will do the rest. If you do not have a physical version of the code, you can also upload it by clicking on the “Choose file” tab. It should be completely visible on the screen you see on the page. Take the QR code you desire to scan and hold it near the camera.Once you’ve done that, you can move onto the next step. If you’re using certain browsers, such as Google Chrome, you may have to allow the browsers to access your device’s webcam.The site uses your computer’s built-in webcam to scan the codes. For starters, you’ll need to visit the WebQR website. There are only a few steps, and you don’t have to download any third-party program that may harm your computer. Although there are some apps available (which we’ll mention later in the article), first, we’re going to explain how to scan codes by using an online QR code scanner. If you’re using a Mac, you should know that macOS does not have a built-in tool to scan QR codes. More information about QR Codes How to scan QR codes on mac.How to scan QR codes on mac using third-party apps.It can be installed in the same way as the open_QRCode.workflow. The QRCode2Clipboard.workflow can be used to extract the content of the QR-Codes into the Clipboard. ( 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 Open System Preferences and add a shortcut to the open_QRCode service under Keyboard > Shortcuts > Services > General: Open the QR-Reader-Mac GitHub project page, select Code, and download the project as a ZIP file:ĭouble click the workflow you want to install. ZBar can be easily installed with Homebrew: brew install zbar The script will automatically open the URL contained within the QRCode in your default browser. You can create a shortcut to the script for processing QRCodes or create a service, as explained below. The open-source project QR-Reader-Mac provides an Applescript script that acts as a wrapper to zbar. It takes a photo as an argument and extracts the information out of any QRCode that it detects in the image. There is an open-source command line tool named ZBar. Becasue it only depends on ImageMagick (exists in macports)- should be easily "compilable" on other OS X versions too. Tested on OS X Mavericks 10.9.2 (and Lion/10.7.5)- and works nicely. You will need ImageMagick what can be installed from macports.Īfter installing the ZBar, you can nicely decode qrcode with a command zbarimg qrcode_file.png Type "sudo make install", and enter an administrator password when prompted.Type "make" to invoke the build process.configure -disable-video -without-python -without-gtk -without-qt to configure the build process, limiting dependencies to ImageMagick. Unpack the the tarball, and open the resulting directory in a Terminal window.(Tried to compile it because it is needed by Image::DecodeQR perl module - but unsuccessful).įortunately, found this link: from citing the next: Unfortunately, the most used library libdecodeqr is depends on OpenCV (gtk2) and it is too hard to compile it on OS X.
