No. Absolutely incorrect. The machines are NOT only Global Entry machines. Miami has machine kiosks which are supposed to be for EVERYONE to use. Some other airports have them also. We have come through Miami at least twice with the new machines. The first time, both of us got through with no problems, no 'x's, June 2014. The second time, my picture was fine, but Eric got an 'x'. This was December 31, 2014. Both times there were a TON of people there and the 'x' line was very short, so it appeared that the vast majority of people were having no problem. Not sure what happened the night you were so unfortunate to come through there, but that is NOT the normal situation now in Miami. Sounds like possibly there was some glitch with the machines that day.
