How Barcodes Work!

How Barcodes Work!

Confounded by the concept of how barcodes work?  I have been in the bar code labeling business for over 23 years.  I came across this video on how UPC bar codes work.  I knew some of this, but the finer details were new to me.  I really enjoyed the detailed explanation.  You too can become a bar code expert after viewing this short video.
