Didn't work at FRA on both exit and entry. Had been over two weeks since I had signed up, and on the day of departure I went to the office to confirm that it was ready for use. Tried at both B and Z exit points, and entrance into B. I told the officer at the manual desk when returning that it wasn't working and he came and tried it for me, he apologized and said to check on it with the office in Frankfurt (where I had registered). If it makes a difference, I hold a long-term "D" visa. The passport reads but system tells me to walk to officer/line. First set of doors does not open. Will report back on if it works in Munich.
