PURPOSE:To miniaturize the automatic transaction devices by defining one of these devices as a master device and providing a communicating function to the master device together with a table for discrimination of transactions and acquiring enbloc the permission of transactions. CONSTITUTION:Master devices PATM and PCD contain slave devices SAD1, and SCD1 and SCDj and SCDk as well as floppy disks FLP1 and FLP2 respectively. A certain customer uses the SCDj and another customer uses the PATM. In such a case, the transaction orders of each device are controlled by a transaction program stored in the PATM. Therefore the transaction data produced to the SCDj is sent to a terminal controller TC when all information on the transaction are delivered to the PATM from the SCDj; while the transaction data on the PATM is sent to the TC when the control is through with each transaction. Then the TC gives the transaction permission data to the discriminated PATM, and the PATM discriminates the SCDj from the received transaction permission data. |
