It also depends on what flight you are taking. Legally the airline is supposed to match the boarding card, to the face and to the passport on an International flight. For domestic they accept drivers license too. For the US it is the Nexus I have been told and `I do not know about that. The Gate check is nothing to do with the border service or the customs.
