As a slight aside, but on the same subject, last time I came into BHX, about 3/4 weeks ago, I noticed one of the immigration lanes had some sort of retinal scan unit installed. It was not operational so we had to queue to be checked by a real person - not too bad on this occasion, maybe 15 mins.
Anybody know what this retinal scan gismo is? Would it reduce immigration times? Does it work?
