I've never really wanted a tattoo, but during cocktail party chit-chat, I always break out with the, "I don't want one, but I know what I'd get if I did."  Which is, a barcode.  Yes, a barcode.  Of course, a Google image search reveals I'm not uniquely creative, see below:



Also, I'd want it to function - scan - and I'd have it programmed for some random product, like Boudreaux's Butt Paste, or some "dollar off" coupon for a product I always buy at the grocery store, like Silk Lite Soy Milk.  However, nothing that would land me in jail! 

Now I can let Google scan my barcode tattoo.  Check out Google's blog for more details.



Beyond product comparisons, ReadWriteWeb did a three-part series  "The Scannable World" - see Part 3:  Barcode Scanning In The Real World for great marketing ideas, aside from my not-so-novel bardcode tattoo!
