For a free app this works pretty well. It may give you some issues if the contrast is bad between text and background or font is too serifed. Usually it gives you something in your contacts that is still faster then entering everything by hand. For me I dont really care about the CamCard contacts but I love that it seamlessly propagates your apple contacts. A huge time saver.
