ASICS are a waste of time anyway, will not or never prevent unauthorized access. I can wander on to a lot of Airfields even in Capital cities and not see a soul for ages. Very few people actuallly check them anyway unless its another set of pencil pushing CASA types doing one of their checks. An easily made fake that was under your plastic pouch in your Hi Vis Vest would not be able to be distinguished from a real one anyway. Hell I know people that have swapped Asics for a day and never been questioned! haha Its a complete Joke.
