Printer Bar Code-like Schema

Jerry here. We all know I like bar codes and other numbering schemes. How about the built-in ID one's printer.

EFF has cracked the code your printer embeds. Or at least if you're using certain color Xerox printers. Read about it here.

Why is your printer tattling on you? To help catch digital counterfeiters of course.

Barcodes & Taxis

No, I didn't see the direct connection between bar codes and taxis at first either. After reading this story I'm not sure I do after all.

Add in a cell phone camera that eats the bar codes and I'm definitely confused.
