I love the potential for facial recognition in the future as long as their are no privacy issues and the public welcomes it without fears over privacy.

Here is my futuristic view of how this can be used, you walk into a Starbucks, it recognizes you, even if this is your first time entering this specific Starbucks, and you say the usual. Your coffee is ordered knowing your 'usual' at Starbucks. Your identity is already confirmed so payment is a breeze, perhaps a pin for extra security. Just a funky idea of what I could see sometime from now.
