Use and Misuse / Re: Do we need to put 's to the following?

I think when we use the word " student card" without 's means it is a pronoun and student here is considered as adj. I think both cases are right, but depending on your purpose you can choose a suitable answer. Using 's when we want to empasize the possession.
