"Failure to carry or produce any additional identification documents that may be required for entry into Canada or the US, i.e. passport.... etc".
I was told the same (and had the information in the membership guide) when I joined NEXUS. However, the rules change on 6/1/09 with the introduction of the
Western Hemisphere Travel Initiative (WHTI), so that now carrying a passport isn't required for a NEXUS border crossing.

That being said, I personally wouldn't travel with a trusted traveler card without my passport.
