1. If I may make so bold, I have a QR generator at http://shkspr.mobi/qr.php

   As far as I’m aware, it’s the only generator specifically designed to work on the phone. You can create your code from within your phone’s browser.

4. In the process of building up a user friendly selection of QR code generators.

   I realise size options would be useful, and perhaps colours - any other desirables?

6. Optiscan lets you scan - in realtime - and create QR codes on the iPhone. You can generate codes from the addressbook as well as by entering text. Optiscan is internationalised for Japanese, German, French, Italian, Spanish, Dutch and English.

   Optiscan is available on the AppStore now - http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=304099767&mt=8

   Reviews:

   BeQRious - “hassle free scanning for iPhone users” - http://www.beqrious.com/show/optiscan-hassle-free-qr-code-scanning-for-iphone-users

   AppStore - UK - I have tested this on QR codes ranging from a few characters to thousands. I have scanned out of focus and crooked, and it always seems to be able to read the code. It’s fast, and it’s accurate.

   AppStore - Italy - Fra tutti i Matrix code scanners questo è l’ unico che decodifica al volo i qr codes prima di fare la foto. Perfetto!

   AppStore - Germany - So schnell kann man gar nicht schauen, wie dieses App Codes dekodiert. Funktionen und Übersichtlichkeit top, hat 6 Sterne verdient!

7. check out this one http://www.morovia.com/free-online-barcode-generator/qrcode-maker.php

   Multiple options and the image is quite small.

9. What format is recommended to format contact information, MeCARD or VCard?

   Posted by Manuel | June 25, 2009, 9:25 pm

10. @manuel MeCard is probably better for QR Code encoding because you can encode the same data with marginally less characters, normally leading to a smaller size QR Code.

11. @Roger I agree with you. But I have tried with some Nokia mobiles (N92, 8500) and they do not read the MeCARD format with the default reader installed on them.

16. @norman
    try visiting www.i-nigma.mobi on your phone (the mobile site identifies your phone and tells you if it can use the software or not) i am currently using the software on a se w810i and it seems to work quite well

    The question…
    Does anyone know of any good software for qr creation on xp?

17. My Mobile Codeatron generates Japanese and generic QR codes and includes an editable raw input viewer that shows you how Japanese QR codes are tagged:

18. An addition to the QR Code generators out there! Generate QR Codes or even Datamatrix barcodes that can have their sizes reduced, labeled, colored, and embedded on images and Google maps!
