The government could just tattoo a barcode on your wrist. Hmmmmmmm...
Good idea! It would eliminate the need to carry money, credit cards, etc. The only drawback is that no one would be able to buy and sell unless they had this mark, and then.....HEY! WAIT A MINUTE!
no doubt, and we already have a unique ‘mark’ (in) our foreheads, its called a retina, i have to wonder where that technology is at today?
