KNFB Reader recognizes and reads printed text from a document camera, scanner or even an inaccessible PDF or image file.
It will not recognize hand writing. It will not reliably recognize credit card numbers. Curved surfaces can be difficult, but improve as the radius increases. Heavily stylized text or writing over or through pictures can be challenging.
KNFB Reader for Windows is a Universal Windows App. It requires Windows 10. In order to do anything beyond recognizing image files with the app, an image capturing device is required. This could be a document camera, a flat-bed scanner or even the built-in camera on the back of a phone or tablet. Not all cameras are created equal, you will have better results if the camera has auto-focus, takes pictures of 5 Mega-pixels or more and includes a flash. Other factors, such as processor speed and available Ram will affect performance.
