Abstract
A transaction processing apparatus includes a transaction processing terminal for registering data related to transaction processing, an external memory connected to the transaction processing terminal for collecting and storing the data related to transaction processing registered by the transaction processing terminal and a monitoring terminal connected to the external memory for periodically accessing and monitoring the external memory. The transaction processing terminal inhibits data transmission to the external memory when transmission of the data related to transaction processing to the external memory goes defective. The monitoring terminal transmits a signal for releasing the inhibition of data transmission to the transaction processing terminal when the data transmission between the transaction processing terminal and the external memory goes defective and then the data transmission is restored to a normal state. The transaction processing terminal releases the inhibition of the data transmission and allows data transmission in response to the inhibition releasing signal from the monitoring terminal.
