Pen Scanner

I believe there is software out there that can use a picture of a text to attempt to translate to digital format so all you need is a good camera and a computer with the appropriate software.

Thanks. The text scanner is interesting. I'll be checking it out some more.

You could take a photograph of it with your camera, make a .pdf of it, and ocr that. i have software called Paperport that will do that and there is also something called pdf converter that will do it. once you've got the .pdf, you open it in word from within paperport and it ocr's it. jwatersphd

A couple of years ago we tested several OCR programs and that was the best one:
