rather old (2003)... but i'm shocked that this has not been reported.

here's the link to the U.S patent office site, describing IBM's patent for unknowingly ink-spraying a readable "code" that can be tracked within stores by the retailer...

United States Patent: 6563423

Conspiracy? Our patent system is pathetic excuse for a joke. Its not even possible to write software of any significance that doesn't infringe on some guys patent somewhere. IBM has so many worthless patents like this its hardly news.
