I can understand the need for an airport ID card, or even the need for some kind of ID card to prove that you are an employee of an airline/company, for example, but what other card do you need?
There is no need for a "crew/pilot ID card." If you are a crew member and you want airside access to your aircraft, then a crew licence and passport (or national ID card) is all that is required.
Don't feed to security trolls!
