Concerning Quick Pass feature.

Can someone give some clarification if you need this feature when you're using the new Avis app (for iOS).

I'm a new PC member and this is my first rental and the question is, if I can skip any counter and just use the app to select my car and go.
Is this possible, or do I need to register for 'Quick Pass' and use the app?

Hope to get some details from you.

Thx.
