iPhone QR code scanners:
There are so many apps to read these barcodes in iPhone and Android markets. I have checked out couple of them to my iPhone. My vote goes to Scan and RedLaser. Scan decodes and shows its content inside the app itself. It has camera light on/off button too. RedLaser decodes and opens the content in safari browser if it is website URL. And the nice feature with RedLaser is one can easily generate QR code and mail it or save to their
iPhone.
