DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a credit card system, and more specifically, to a non-contacting type radio frequency recognizing credit card system in which a credit card inquiry is possible in a state with a credit card not contacted with a card reader, and in which the credit card inquiry time and the data exchange time between a credit card and a card reader are drastically reduced.
DESCRIPTION OF THE PRIOR ART
Generally, a credit card possessor can buy commodities and services without paying cash under the guarantee of the credit card managing company, and also can carry out non-passbook transactions with a bank through a cash payment apparatus.
The size of the credit card has been determined as 3.375 inches, 2.125 inches width and 0.03 inches thickness internationally so that they can be used worldwidely through subscribed stores. The data for judging on the authenticity of the credit card holder are stored in the magnetic strip of the credit card and in the card managing company. Upon verifying the data, the subscribed store approves the transaction.
FIGS. 1A and 1B illustrate the basic external appearance of a credit card.
As shown in these drawings, a credit card 10 has frontal face 20 on which there are shown a card number 21 consisting of 16 Arabian numerals, a name 22 of the card owner, an expiry dare 23 of the card, a name 24 of the card issuing company, a logo 25 of the card issuing Company, letters "local" "international" and a hologram 27 as the means for preventing illegal copying of the credit card.
In the rear face 30 of credit card, there are shown a magnetic strip 32 which stores the identification of the card owner, the paying passbook account number, and the validity of the credit card.
In case where a commodity or a service is to be paid by using such a credit card, the credit card is inserted into a card reader, so that the magnetic strip of the credit card would pass contactingly through the card reader. The credit card number thus read by the card reader is transmitted from the card reader through an electric line (telephone line) to the credit card managing company. The credit card managing company checks on the payment limit and on the existence or absence of dishonored transactions, and it transmits an approval number or a disapproval number to the card inquiry terminal.
However, the above described conventional card inquiry system takes too much time several seconds or several scores of seconds) in completing the card inquiry. Such a time consumption in the conventional system has been a serious impediment in broadening the area of the credit card utilization.
Another problem in the conventional system is that credit cards are apt to be damaged and thus the reading errors in the card reader are very frequent.
In the conventional system, the card reader reads the data of the magnetic strip by contacting with the magnetic strip, which may shorten the life of a credit card. When a credit card passes through a card reader, if the passing speed is too fast or too slow, then reading errors are occurred, and if the such an errors are repeated, the magnetic strip would be worn out and consequently the life of a credit card would be shortened.
SUMMARY OF THE INVENTION
The present invention is intended to overcome the above described disadvantages of the conventional system, and therefore, an object of the present invention is to provide a non-contacting type radio frequency recognizing card (hereinafter "RF card") system, so that the card reader may read the information in the card in a non-contacting manner. In the present invention, the information can be exchanged between a credit card and a card reader without being contacted with each other.
Another object of the present invention is to reduce the card-reading time drastically, so that a credit card may be used to pay traffic fares or the like which requires the card-reading time to be extremely short.
It is still another object of the present invention to provide a no-battery type RF credit card. I
