Then what's the point of the NEXUS card? Also, I no longer have an I-94, my last travel to the US was March last year.
You use the NEXUS card for travel by land or sea (if they have NEXUS lanes/facilities). It also has your known traveler number and you can use it as an ID to travel domestically within the US and Canada. Even though you can't use it on a kiosk (in the US anyway), it's still proof that you have NEXUS privileges. I'd wager you should be able to use your Canadian PR card in GE kiosks in US airports, but I'd rather someone else verify that piece of information.
