ABSTRACT:
A POS system including at least one store server and a plurality of POS terminals. Each POS terminal includes means for transmitting transaction data to the store server as a transaction occurs at the POS terminal, means for querying the store server for transaction data relating to a transaction that occurred at another POS terminal, means for instructing the store server to cancel the transaction that occurred at the other POS terminal, and means for executing a transaction cancel instruction received from the store server to cancel a transaction that occurred at the POS terminal, and the store server includes means for receiving a transaction cancel instruction from a POS terminal other than the POS terminal at which the transaction occurred, and for transferring the transaction cancel instruction to the POS terminal at which the transaction occurred. With this configuration, the POS system allows any transaction, including a sales transaction, originally registered at any POS terminal, to be canceled through any other POS terminal in the POS system. It is also possible to correct transaction data without canceling the entire transaction. As a result, transaction data can be readily corrected when an operator's input error is found or when a purchased product is returned by a customer, and an easy-to-operate POS system can thus be provided.
