If it’s Monday, Tuesday, Wednesday and Thursday, it must be Barcelona and the 3GSM World Congress. I was here to chair a session on biometrics, identification and authentication. With 38,000 delegates and an entire exhibition village, it’s a bit of a do. I have to say I’m quite enjoying the conference as there were one or two quite interesting presentations (which is not always true of this kind of industry jamboree). One of the conference newspapers is headlined “The Circus Comes to Town”, which is just about right.
