A Japanese company that runs a popular online site to resell goods says it has started using AI to combat fraud.



The operator known as Mercari is responding to an increase in scams and criticism that existing countermeasures built into its app are insufficient.



Mercari says its tougher measures introduced on Wednesday will identify and block users abusing the service. It says AI will be used to track suspicious transactions.



One type of fraud involves buyers who return items asking for a refund, but the products they send back are not the original ones they received.



Mercari says it will also crackdown on trade in counterfeit brand goods.



A company official says Mercari aims to take the lead in fighting fraud using technologies such as AI.
