I got this from Sally:
I just read the Google logo of the day, and underneath found this website:
It is explained quite nicely, and basically what it does is convert your personal information into a barcode… which you can than print out into a name tag, should you be so inclined. Even better (or worse, depending on point of view), you can hit the scan button provided, and find out what your monetary value is. Fortunately for me, I have a very high opinion of my self-worth, because by barcode standards, I’m ringing up at a measly $6.44 (I think that I might be worth more if cut up and sold for parts).
