Desktop QR Code Reader

What are QR Codes?:
A QR code is a lot like a barcode you see on most products. QR codes are a great way to share information like websites and contact info. They can be scanned using your camera equipped device and a proper QR code processing app (For Android, I use the Barcode Scanner App, and on iPhone I use QR Reader for iPhone.) Once the code is scanned and processed, it takes you directly to the URL on your device, or shows you whatever else was encoded in the QR code. I love the ease ability of QR codes, just a quick scan, and the content is on your device. For Example, there is a great plug-in for Google Chrome called QR-Code Tag (For Firefox there’s Mobile Barcode) which lets you generate a QR code for the site you are currently viewing. This is super handy if your reading an article, and need to take it on the go. So, what about reading a QR code from your phone to your desktop computer? Well, surprisingly that wasn’t as easy. I spent some time digging around the internet, and could not find a good cross-platform application for reading QR codes onto your desktop computer. The only thing I found that was somewhat close, was an AS3 library. At that time, the only thing using the library was embedded on a web page… which isn’t the most ideal solution if your wanting to just scan something quickly. So, I took the initiative to implement the library into an Adobe AIR app that can be run on basically any system. I call it QRreader. Download it HERE

  1. Have you thought about having a minimize feature. Or something so I don’t have to look at my ugly mug while the program is running?

    please let me know. If you do not have plans for this…I could also contribute…but I think the code is read only at this point.


  2. As of today’s sports world’s most influential brands in 30 years of the development process, Nike on their own emerging technology not only changed people’s understanding of the traditional sports products, but also changed the pattern of global sporting goods category. Following the first smart chip adidas sports Nike Free Shoes to create a world of change began, Nike sports shoes to the title of king launched the revolutionary technology running shoes to compete Free series.

  3. I am a teacher, but not a programmer. I am looking for a way to use QR codes for attendance tracking. Does anyone know how to get the result (which works fine for me by the way with a new Powerbook 17″) into a database (like filemaker or something similar)?

  4. Doesn’t work for me on Win 7 64bit either, like others. Built in webcam works fine, app loads and activates camera but after that it just doesn’t read anything. One thing I noticed, not sure if it’s related or not, but the image in the camera window is reversed. Perhaps the app needs to flip this around.

  5. I does work on Mac Pro iSight. you just have to make sure you get the QR to register red for 2 seconds to decode….its a bit tricky

  6. Is there a way to make this enter the the QR info into wherever the cursor happens to be?

  7. Using Mac OSX 10.6.7 ; most recent version of Adobe Air. White brackets turn red & nothing happens.

  8. Works great! I install on XP Pro. Be sure to mention that the little gear in the upper left corner needs to be clicked and the “Open URLS automatically” checkbox needs to be checked for truly complete function.

  9. It doesn’t work for me either. The error message seems to pin it on Adobe Air. I think it might be becuase i have the 64 bit Windows 7 and Air for Windows is only 32 bits.

  10. Hi
    Excuse my stupidity, but once I’ve downloaded and extracted the Qreader files, how do I run it?
    (using Linux Mint)

  11. Have anyone tried using windows 7? I have been trying the software for 1 hour and still unsuccessful to read qr code … 🙁

  12. You can receive cards from others by scanning their QR Code. Last but not least, whenever you update your QR Card information, all your contacts that already received your QR business card will be able to see and access the new information automatically. Check for more info at

  13. It doesn’t seem to read those photo shopped codes (there’s one that was a ghost busters theme) and I tried to decorate my code. I don’t own a phone that can read these codes, so I wanted to use this app to test my codes before releasing them. They do work black and white, but colored and decorated, no…

  14. What I done was actually printed the qc code and laid it flat on my kitchen counter. My built in camera on my sub-notebook is only a .3 MP which I thought might be too low quality to pick up anything but it did. To get the beeps there is options section of it and has a part where it will open URLs automatically and have the option to turn on beep.

  15. I HAVE TRIED FOR 2 HOURS ON MY PHONE AND COMPUTER AND I CAN NOT SCAN THE QR CODE… i can not scan the epic adventure cruize qr code. i FEEL THAT THIS IS A SCAM AND YOUR CONTEST HAS BEEN A WASTE OF MY FAMILIES TIME. I feel very frustrated enough to tweet about it.

  16. I had difficulty scanning codes as well. Like the other previous posts, the brackets turned red for a bit, and sometimes I heard a beep, but nothing happened. The app is fairly light sensitive. If you are having trouble, move the QR code to better lighting, and it will scan consistantly.

  17. This is brilliant for those of us who don’t have smartphones (yet). I tried the download and it worked once on a large QR code printed in good contrast. It did not work on newspaper or magazine codes though. Is it my camera or what am I doing wrong?

  18. Today i make a test whit a new camera, and the picture get mirrorfaced.
    SÃ¥ I could not read the QR code. I Swith to another Camera and the same result.
    Then i test with QuickMark and it´s work fine with the cameras.
    Hove com?

  19. Red frame flashes but no beep or url in Windows XP. Does any one have any advice? Looking forward to getting this to work.

  20. I am trying to get this to work on a Mac Book Pro and can not get it to work, is it due to the fact that the built in iSight camera mirrors everything. And if so is there any way to make it work? I have tried installing iGlasses but it does not start up with this program. Thanks for your work and efforts on this this is great for those of us without a smart phone.

  21. Works perfectly! Well done Dansl. I’d love to see a “PRINT” button for QR codes that contain a text message rather than a URL. Thanks!
