Answer 1

The iPad 2 camera does not have auto-focus. Zbar doesn't play well with fixed focus cameras:

If your camera is fixed focus, you can try trading off between resolution and focus by playing with the distance of the symbol from the lens. ymmv, but usually your only recourse in this case is to use a better capture device!
