While most observers acknowledge the merits of some uses of this biometric identification, does the technology evoke fears of a "Big Brother" surveillance state? And is the technology itself secure? Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRT World.
