Abstract
A non-contacting type radio frequency recognizing credit card system is disclosed. In the conventional credit card system, the card recognition is carried out by contactingly inserting a credit card (40) into a card reader which is connected to a card managing company. Therefore, the card may be damaged, and the card recognition time is extended. The non-contacting type radio frequency recognizing credit card system according to the present invention includes: an RF card (40) for being activated by receiving radio frequency from a card terminal (70) so as to transmit its own card number to the card terminal through radio frequency; the card terminal radiating a radio frequency to induce an electric generation in the RF card, and the card terminal transmitting a card number data (received through a radio frequency) to a wire-connected terminal computer (80); and the terminal computer reading the card number data from the card terminal to make an inquiry into a black list, to make a decision for issuing an approval of a transaction or a denying of the transaction, and to transmit the result of the decision to the card terminal.
