Cauzin effect

[Andrew Burton]

errr... be very difficult to tell for sure.

An article I read in 80 Micro (I only have issues 1 to 60, so must be between 1980-86) stated their were only 7 types of barcodes.
In a recent Lonelygirl15 "episode" (err.. back in June/July?) on YouTube Bree (played by Jessica Rose) stated that there are now 300 types of barcodes. No idea whether that's true or not, but certainly barcodes are everywhere - we use them to register samples at the lab I work at (much quicker to scan a barcode than to manually enter primary data - location, analysis required etc.)
I'm not entirely sure how they can differ that much as they are essentially visual binary, with special markers to mark the start and beginning of the barcode.

I've got a Cauzin reader someplace around here, and I am pretty sure it 
was the first TWO dimensional type barcode. They must have had a pretty 
strong patent because it was still in use as recently as about 5 years 
ago for trade show badges. Anybody know if its tied into the stuff used 
in shipping now, postage stamps etc.?
