Ahhh YPJT
And exactly what I tell the security boffins. There is no requirement to display the ASIC card in the terminal at all. Unless you are in an area that is not available to the general public.
You must wear it airside or once you access restricted areas.
Funnily enough if you are with another pilot who is wearing one and they try to bust your chops you can always say you are under supervision of an ASIC card holder
