Forget pay per click, how about pay per cackle? In a new digital take on admission fees, a comedy club in Barcelona used facial recognition software to charge per laugh, rather than per show.

The scheme, which uses facial recognition software, is now working so well that its helping the Spanish venue turn a larger profit. Entrance to the club is free, but each laugh amounts to €0.30 (£0.24) – to a maximum of 80 laughs for €24 (£18). The average ticket price is now up by €6 and it has resulted in 35 per cent more spectators.
