How come there aren't scads of counterfeit boarding passes? I've taken to checking in online and printing the pass on my home computer. Seems like it would be child's play to counterfeit something like that. If that's all that's necessary in a sterile area, it would seem like a weak link. I'm kind of surprised there isn't work being done on some common form of international ID that is hard or impossible to forge (though "imipossible to forge"is probably one of those falsely comforting phrases). Now that British passports are a hot subject, having been used in an assassination, I am really wondering when global ID will start to be pushed. The fact is that there were two copies of all those passports and only after the killing did they discover it was so.

Anybody against the idea?
