I'm wondering just how many people have actually ever had to use theirs.
In all the time I have had my AVID I have NEVER been asked for it and at a couple of places where I was fully expecting to be asked for some or any identification I wasn't. The places are all airports both primary and secondary. The primary ones I was fully expecting to be asked for ID as they tend to do (as a passenger) when I fronted the check in counters to check in baggage (I had already checked in online or at a do-it-yourself position in the check in hall) and the secondary one was when gaining airside access and needed to call one of the mobile security persons to open a gate for me to get in.
I am of the opinion that these alleged security measures are nothing more than a revenue raising rort and do absolutely nothing what so ever.
