Cambridge (UK) based company Airsource have released Optiscan for the iPhone. Airsource have taken the standard Google QR code decoding engine (Zxing) and have both tweaked the image processing library and removed the need to press a button to snap the QR code to end up with a very fast scan/decode time. If Optiscan fails to decode a QR code the camera preview will simply continue to show the image, allowing the user to try and improve lighting/stability. Ben Blaukopf, CTO of Airsource Ltd told QRMe " ..However, that is where the key benefit for Optiscan lies - the automatic capture means that the iPhone effectively tells you when you are sufficiently well aligned, whereas with other readers you are required to guess. Perceived performance is also much higher due to the reduced user interaction necessary - 0 button-presses with Optiscan versus 2 with a similar product".
