The RedLaser application is dirt-simple. When the camera activates, just aim the cross-hair at a barcode and when the software is happy, it automatically takes the picture. No need to press a button and wonder if its a good shot. I tried this in two stores (Fry's and Toys-R-Us) under different lighting conditions and it worked each time.
Once the barcode has been scanned, the application does product searches on Amazon and Google to find prices. For example, while in Fry's there was a Buffalo DriveStation (external harddrive) for $86. Is that a good deal? I used RedLaser to find that other online stores were selling it for $100-132 so the $86 price was a bargain. Yes, I could have manually entered the barcode but its so much easier to just snap a picture.
And RedLaser is available to other iPhone application developers as software development kit, so I expect new, innovative uses to follow.
