Hi,

 I'm writing an app that will print out a page with several questions (in random orders) and an answer box. Each question will be barcoded for identification purpose. This can be done and users answer the questions. What i'd like to do is to then scan these papers and automatically detect the question using the barcode and capture the contents in the answer box. There could be multiple questions on one page and multiple pages.

What would be the best way to implement the scanning bits for the above?
