Good evening.

This is my first post so go easy on me :-)

During the last couple of weeks I've been changing planes quite often in Frankfurt passing between A and B terminals. The IRIS Scan at passport control (which is really useful when there is a queue) doesn't seem to recognise my passport on the last 3 - 4 attempts (I haven't changed the passport and it still has a couple of years of validity). Has anyone else experienced the same problem recently?

Kind Regards.
