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 a 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.

Système de cartes de crédit à reconnaissance par radiofréquences du type sans contact. Dans un système de cartes de crédit traditionnel, la reconnaissance des cartes s'effectue par introduction, avec contact, d'une carte de crédit (40) dans un lecteur de carte raccordé à une société de gestion de cartes. Ceci peut abîmer la carte, et le délai de reconnaissance de la carte est alors prolongé. Ledit système de cartes de crédit à reconnaissance par radiofréquences du type sans contact comprend un carte R.F. (40) apte à être activée par la réception d'une radiofréquence en provenance d'un terminal de cartes (70), de sorte qu'elle transmet son propre numéro au terminal à l'aide d'une radiofréquence. Le terminal émet une radiofréquence afin de provoquer un production d'électricité dans la carte R.F., puis il transmet des données de numéro de carte (reçues par l'intermédiaire d'une radiofréquence) à un ordinateur terminal (80) à liaison par fil, et ce dernier lit les données de numéro de carte en provenance du terminal de cartes avant de consulter une liste noire, de décider de la validation ou du rejet de la transaction, et de transmettre le résultat de cette décision au terminal de cartes.
