Mini-barcodes for newspapers and magazines (nytimes articles, free registration required). What I don't get is why people are using such a complicated system that requires all sorts of finicky technology to work. Why not a small print 6 or 7 digit code at the end of the article? Then have a prominent text box at the top of each page on your web site, people plunk in the code, press a button and hey presto. Faster, cheaper, easier. id: 2109324
