The stars has something to do with HK locals who have parents born in HK.
1 star would be from 11-18 years and then when you re-apply for your adult ID you get 3 stars. The stars also mean that you are of HK/Chinese nationality and may not hold a 2nd nationality unless you drop the HK/Chinese one.
At least this is my understanding of the star system but it is completely separate to having a permanent or non-permanent ID card.
