There are just too many passwords in this world... and I'm getting tired of it. There are only so many cubic millimeters in my brain... and it's getting full. As a matter of fact, add to that Pin Numbers, User Names, Log Ins, and Alarm Codes... and it's completely out of hand.
Why can't we replicate the movies? Your thumb becomes your instant password for.... Everything. Good at restaurants, the bank, your computer, the grocery store... If my thumb gets rejected, I'll hold up another finger.... Log me in!
