Downloading the Kaywa QR reader ?
Kaywa QR reader takes snapshot
I tried googling it and found a site, but when i select Motorola on the download page it doesn't have this phone listed.
You're right, the EX124g isn't listed but you can still download the app. Using your web browser on your phone, go to the URL:
and there you'll have to choose among these Motorola phones (as of today): KRZR V3, various version of the Razr, and the W395. I just chose the W395 and was taken to a page with a small "Click here to download link. The KaywaReader.jar file was 316 KB and took about 20 seconds to download. Once downloaded, I said "yes" to install and chose to install it on the memory card rather than the phone. The whole process took me about two minutes, even though I went slowly, taking notes so that I could report back here.
Launching the App
To use the reader, you launch the app and click on the take Snapshot and then the app again asks for permission to use the camera so you have to press OK again (this is the only real hassle of this app). Then once it reads the code, you can go to the encoded web site at which point the app launches the web browser and shuts itself down.
Reading QR Codes
Using the Kaywa reader, I was able to read the test QR codes on Kaywa's website when I displayed them on my computer screen. The code pointed to a German site (see pics). I also pointed the phone at and was able to read a QR code in a magazine for a local orthodontist in Northern Virginia.
Reading Bar Codes
I was NOT able to read any traditional bar codes with the straight lines using this app, though I don't think it was designed to do that anyway.
Kaywa Reader Settings
If you go into the menu, you can set an option for "Close-up" which may come in useful for reading blurry images or images from a newspaper which are not always that clear.
Hope this helps.
