Abstract

A merchant terminal or a customer terminal receives first input(s) associated with a first POS transaction with a first customer. Based on the first input(s), it is determined that the first POS transaction is in a first item-input portion and so the merchant terminal is designated as a state control terminal for the first POS transaction. Based on a trigger event occurring for the first POS transaction, it is determined that the first POS transaction is in a payment-input portion, and the customer terminal is designated as the state control terminal. Second input(s) associated with a second POS transaction with a second customer are received prior to receiving payment input to the first POS transaction and while the customer terminal is the state control terminal for the first POS transaction. Based on the second input(s), it is determined that that the second POS transaction is in a second-transaction item-input portion.
