There seems to be confusion here with the following comments:

The NC Turnpike Authority
uses (or rather it will use) a system called NC Quick Pass
. This is not E-ZPass. NC Quick Pass utilized tollways will be some of the first fully automated toll systems in the US (no physical payments on the tollway, it's all digital).
You currently can not use other "Pass" systems with NC Quick Pass, however they are working to allow existing users of services like SunPass and E-ZPass. To further this, the NC Turnpike Authority is a founder of the Alliance for Toll Interoperability
so that people don't have to have passes for every state.
So no, I don't think that NC is "quite unsophisticated" in their tollway implementation. In fact I think NC is quite the innovator here.
