Question by Nate: How does the Leap Frog “Tag” reader work?
Product from leap frog called tag which allows you to touch a word or picture and it tells you what it is or reads to you. I don’t need the obvious answer of it reads to you. I’m looking for how it does this… what is embedded in the books to allow this?

Best answer:

There is a small camera in the tip of the pen, which “sees” the words. And I think this camera image is probably scanned and read through a computer chip. Check this site.
