The YTH (Domestic Clearing and Settlement) System is a system that handles the clearing and settlement of a transaction between two banks when a transaction is carried out at a different bank's POS or ATM using a card issued by another bank. Records are sent to the YTH system by participants, and these records undergo daily clearing, multilateral netting, and reconciliation (settlement).
