WTF does an ASIC denote if not authorisation?
It only denotes that you have undergone a standardised identity check. (It's what the "I" means). It has no authorisation purpose at all. You are required to demonstrate a need to be in an area requiring identification by ASIC card as well. That is a point that is often misunderstood by ASIC holders. It does not give the holder carte blanche.
