Abstract
The credit card information management system checks the creditability of a credit card intended to be used for purchase of goods or service by using the card information owned by member stores of credit companies. A host computer of the card management center outputs information regarding the validity or invalidity of a credit card of a customer member of a credit company as card information, a transmission facility wirelessly transmits digital data of the card information. A receiving facility of a member store receives radio signals of the card information and checks whether or not there is any missing of data. If any missing occurs, a transfer of the missed data is requested to the host computer. A terminal computer extracts only the card information necessary for one's own store from the data outputted by the host computer and data outputted in response to the transfer request and stores the same in memory, and the terminal computer outputs judgement of validity or invalidity of a credit card inputted into a card reader.
