I tried my new GE card at LAS last week with mixed success.

I showed it to the TDC and her response was: "We don't accept this, it doesn't even say who issued it." I took the card back and looked all over it and she was right. The front says "Global Entry" and the back has the SENTRI logo, but it doesn't actually say anything about CBP or Homeland Security (!?).

I pushed back a little and she called the supervisor over, and another TDC worker, and none of them had ever seen it before. The supervisor seemed interested but eventually they looked at my ticket, saw that I was traveling internationally, and asked to see my passport (which I showed).

So they didn't really take it, but they didn't really reject it either. The supervisor said they hadn't been trained on them yet.
