Bio data

Its only been a few weeks since I was last in the US, but things change. Fingerprints of your index finger have been around for a bit, but now the sequence is more complex. Four fingers of your right hand, then the thumb and repeat the process with the left. Net result queue length doubled, and very little by way of interview. Border guards focused on new technology not questioning or probing. On a par with asking me every-time I come in to sign a form to say I don’t intend to undertake terrorist activity. All the bio data in the world will not substitute for an alert human. I wonder what they will want next? Bodily fluids?
