About the site

I'm interested in barcodes from a mathematical/computational standpoint. What information is in there? How can I get it out? This site shows some of what I've discovered. Right now, I'm primarily working on the various postal barcodes, because they tend to be easier to read by eye.
I have no interest in practical matters such as how barcodes are used in real life, or where you can buy software or hardware to read and write them, and so on. There are plenty of other fine websites where you can read about those things.

About me

My name is Bob Mathews. You have already figured out that I'm an engineer. Barcodes have nothing to do with my work. This is something I do for fun.
