Woolworths has begun testing a new trial that will see artificial intelligence (AI) being put into checkouts to detect the fruit and vegetables we are scanning.

It is already in place in three stores across Sydney.

The technology will see customers able to weight produce on the machine and the AI will pick a number of products for the customers to choose from, based on what it thinks it is.

A manager for the supermarket posted to LinkedIn to show how the new technology is supposed to work.

The move comes as supermarkets try to stamp out mis-scanning, or stealing, from the checkouts.

Self Serve checkouts are now believed to account for 8 million transactions a week.
