In NC will a open container charge show up on a background check?

I was charged with "possession of an open container of an alcoholic beverage in the PASSENGER area of a vehicle", meaning I was NOT driving. This was 4 days ago. Today, I went to see the Clerk of Court in my county. They explained that this was an INFRACTION and that NO infractions show on your background check, even if you are convicted of that infraction. Only "criminal acts" appear on a background check and my charge is an INFRACTION.
