With all the latest hype about QR-codes, you must certainly would want a QR scanner on your phone. Especially if you’re living in Japan, where QR-codes are most popular.
Well, the N900 sure has a QR-scanner, and a pretty good one! mBarCode, together with a QR plugin can read both barcode and QR information.
You can get both mBarCode and the QR-plugin from the Extras repo:
apt-get install mbarcode mbarcode-plugin-qrcode
Launch the application and now you have a very good scanner! Target your camera at a QR or a barcode and the information gets read almost instantly. Links and other “can-be-malicious” content is shown to you before getting opened with your tap. You can even check the shortlinks by copying them and visiting this site.
You can also store the scanned code into a file, or read the code from a file you stored. That way you can use the codes later, or scan the codes downloaded from a website.
With all that, mBarCode is a must-have if you’re used to dealing with QR and barcodes.
