CES 2018: Food store AI sees what you put in basket

An artificial intelligence-based system is being developed to spot what goods shoppers pick up in convenience stores so that they can be charged without having to queue at the till.

A prototype version of the technology by the San Francisco start-up Aipoly is on show at the CES tech show.

Amazon is known to be working on similar technology.

BBC Click's Lara Lewington tried it out.
