Detroit USA - airport telling each passenger where to go

Misapplied sciences. Albert Ng's idea - a motion sensor. It recognizes you and your boarding pass. 

Up pops a message overhead which only you can see. It greets you by name. It tells you where to go at the airport. How long it will take in minutes. 

As you walk along, Lighted arrows guide you. 

Amazing. Wow.

Should You Guard Privacy and Shred Your Boarding Passes For Security?

Problem
Some people show their boarding passes on media and this is a security risk. Also throwing them away is a risk.

Answer
Some people prefer not to print their boarding pass but keep it on their mobile.
What if you lose your mobile or internet connection? Or a third world airport official claims you need a printed copy so he or she can charge you for printing it (either official charge or a bribe).
In theory if you have ID the airport staff can print your boarding pass.
I like to photograph my boarding pass. However, I shall think twice now.
If you shred your own boarding pass or other document with scissors put the two halves in different bins at different locations on different days.
