I used global entry for the first time to re-enter the US. The Kiosk prompted to look at the screen for a photograph, then said to continue to the officer. There were no buttons/prompts, this all happened automatically. The officer had a screen which appeared to have all the photos taken, they confirmed my name, handed me a card that said "Global Entry", then said to continue through to baggage claim. After baggage claim I handed over the card and that was it.

I was under the impression the kiosk was meant to ask the customs declarations questions. I didn't have anything to declare, but should I have done something differently?
