digital membership card and tracking non-ticket benefits

I was hoping someone could confirm my thoughts, please!

We are on v15.2, and have rolled out digital membership cards.  Am I correct in thinking that while I can set up a special access area in NScan to allow entry into the area (Donor Lounge) based on scanning the card,  I *cannot* scan that card and have it track benefits (free snack) unless it is set up as a ticketed event?  

Thanks!
