Any of the GE machines (as shown below) which have been in use in Canadian airports for at least 6 or 7 yeas now accept NEXUS cards instead of passports. This is true
only at Canadian pre-clearance airports. If you land directly in the US you must use your passport, even though the machines are the same.
