It's sci-fi. How many thousand people are in an airport at one time? If they saw you doing something and decided to shock you, how long would it take them to scroll through the list of names and activate your bracelet?
"I think his name was Frank Smith.
OK...let's see....I've got a Fred Smith?
That must be it. OK...there.
YOW!!!!
Ohh....sorry. That's not it. Come to think of it, maybe his name was George...."
Maybe they could also assign you a T-Shirt with a bar code printed on it and give the airport security guys a price scanner gun.
