Clearly the sticker is not itself any kind of security device. That, or it's an extremely good one.
I don't know if someone not GE trying to use the kiosk would get as far as getting the 'X'. I do remember once in ATL when the kiosk was having trouble with the initial passport read. No cards were being kicked out then.
Supposedly the sticker is quick verification
if the kiosk is down and you have to jump to the front of a line. However...I wasn't even given a sticker when I signed up. I finally got a sticker when I had a daytime layover in ATL last fall. Two months later I came through ORD for the first time and the quy at the
customs podium took my kiosk card and passport and demanded to see my sticker! I don't know how he thought I could get a kiosk card without being GE. I guess if I hadn't had the sticker, he would have sent me to the back of the customs line.
