PURPOSE:To equalize a load of validation terminal group managing device and to improve a processing speed by providing a data transmission means between a card validation terminal group managing system and a computer, a card validation terminal equipment and the card validation terminal group managing system and a selecting means for selecting the transmission destination and a transmission control means. CONSTITUTION:When the data relating to a credit transaction is transmitted to the first cluster controller 1 from CAT 3, the controller 1 transmits to a host computer 5, the computer 5 discriminates whether the credit card can be used or not. The controller 1 transmits the transaction establishing data to the second cluster controller 2, the controller 2 transmits the data to a store controller 6, and then, the controller 6 stores and manages the transmitted transaction establishing data. When the similar data is transmitted to the controller 2 from a CAT 4, the data is transmitted to the host computer 5 through the controller 1 and the discrimination result data is transmitted to the relevant CAT 4 through the cluster controllers 1 and 2. |
