NFTs – or non-fungible tokens – are effectively a digital proof of sale, and it's fair to say they’re having a moment.

So how exactly do NFTs work? And could they transform the way we do business in the future? We speak to financial technology expert James Bowden, a lecturer at the University of Strathclyde.
