Abstract
A credit card system has a card having at least identification information and management information recorded thereon, a first system for determining whether a credit card can be used or not, and a second system for determining whether the credit card can be used or not. The first system has a communication device for communicating with the second system, a card reader for reading the identification information and the management information recorded on the credit card, and a system processor for determining whether the credit card can be used or not, and judging whether usability of the credit card is to be determined by the first system or the second system based on the management information recorded on the credit card. The system processor indicates or displays resultant data as to whether the credit card can be used or not as determined by the first system if usability of the credit card is to be determined by the first system, and inquires the second system about usability of the credit card through the communication device if usability of the credit card is to be determined by the second system, and indicates or displays resultant data as to whether the credit card can be used or not as determined by the second system.
