Universal Product Code Secrets (Bar Codes) | Cracking the Universal Product Code

A very nice article on how bar codes work. It doesn't really get into some of the newer bar code technologies, but covers the basics very well.

Sure this article could have a dark side to it (what doesn't when it comes to information). But I find this sort of info interesting. Understanding how something so pervasive in our society works is important.
