Is it possible on an iPhone app to take a picture and extract an string from the picture? We’d like to make our app to look for a serial number on a database (very long number) without the user having to type it.
Is there any Cocoa/Objective-C API for this or any C/C++ library that can be used in an iPhone app?
Thanks in advance!

Here is a demo that makes use of the tesseract ocr engine.
