If payments are always approved by the payer with their PIN / FaceID, then the idea of a fraudulent charge is just undefined.
Like you hand cash to someone. The transaction is done at the moment money changes hand. You don't get to call someone to snatch the money back to you against the payee's will.
For online purchase, for example, buyer pays the marketplace (e.g. taobao.com) to temporarily hold the money -> seller ships the goods -> buyer confirms goods are received -> marketplace pays seller. If there is a question, you take it to the marketplace to sort things out according to marketplace & seller policy. Either way, the payment provider doesn't concern itself with any of this - it only routes money according to payer's request.
