A desired oil type is selected and operated from among oil types such as gasoline, high-octane gasoline and light oil. Then, the card terminal transmits the remaining amount of the inserted card and the selected oil type to the POS device. The POS device compares, for example, the unit amount per liter of the oil type transmitted from the card terminal with the remaining amount of the card, and if the remaining amount of the card exceeds the amount, transmits a refueling permission signal to the corresponding measuring device. This allows the user to refuel his or her vehicle from the scale.

[0004] When the refueling is completed, the card terminal debits the amount of the remaining amount of the inserted magnetic card according to the refueling amount in accordance with an instruction from the POS device, and then returns the magnetic card. On the other hand, as a result of comparing the unit amount corresponding to the oil type transmitted from the card terminal with the remaining amount of the card, if the remaining amount of the card is insufficient, the POS device notifies the corresponding terminal of the shortage of the remaining amount. In this case, the user cannot refuel.

[0005]

In the conventional self-refueling system, when the unit price of the oil type selected by the user is larger than the remaining amount of the magnetic card, the self-refueling system has the remaining amount on the magnetic card. There was a problem that refueling became impossible. Therefore, an object of the present invention is to enable refueling using a magnetic card even when an amount less than a unit amount of the oil type selected by the user remains on the magnetic card.

The POS device 3 also transmits a refueling permission signal to the corresponding measuring device 2. Thus, the user can start refueling from the measuring device 2 to his / her own vehicle in accordance with the oil type data, and step S
The process shifts to refueling by the corresponding measuring device 14. And
When the refueling by the measuring device 2 is completed, the PO
The refueling end is transmitted to the S device 3 together with the refueling amount.
Then, the POS device 3 calculates the amount of money according to the oil type data and the amount of refueling, and withdraws the calculated amount of money data from the credit card 5 in step S16. The debit amount is transmitted to the card company center 6 together with the credit card 5 data, and the center 6 subtracts the debit amount from the user's bank account amount based on the credit card 5 data. At this time, the POS device 3 transmits the refueling end information to the card terminal 1 together with the terminal number. When receiving the refueling end information, the CPU 11 of the card terminal 1 controls the reader / writer 14 in step S17 to eject the credit card 5 from the card insertion slot.

When refueling using the magnetic card 4, if the remaining amount of the magnetic card 4 is smaller than the unit price of the selected oil type, a refueling disapproval signal is sent to the card terminal 1.
Notified to the side. In this case, the CP of the card terminal 1
U11 determines that "fueling is possible" in step S7 as "N", and controls the voice synthesis IC 19 in step S18, for example, from the speaker 21, "Insufficient balance. Insert a credit card." Is sent. When the user listens to the voice guidance and inserts the credit card 5 into the card insertion slot of the reader / writer 14 in step S19, the reader / writer 14 takes in the credit card 5, reads the data, and transmits the data to the CPU 11.

Notify the card terminal 1 side. The POS device 3 also transmits a refueling permission signal to the corresponding measuring device 2. Thus, the user can start refueling from the measuring device 2 to his / her own vehicle in accordance with the oil type data, and step S
It shifts to refueling by the corresponding measuring device 2 at 21. And
When the refueling by the measuring device 2 is completed, the PO
The refueling end is transmitted to the S device 3 together with the refueling amount.

Then, the POS device 3 calculates the amount of money according to the oil type data and the amount of refueling and transmits the amount of money to be paid to the magnetic card 4 to the card terminal 1 together with the refueling end information among the amount of money calculated. When the CPU 11 of the card terminal 1 receives the debit amount of the magnetic card and the refueling end information from the POS device 3 in step S22, the CPU 11 controls the reader / writer 14, deducts the received amount from the remaining amount of the magnetic card 4, and sets the remaining amount to “0”.
In step S23, the magnetic card 4 is ejected to the card insertion slot in step S24.
At this time, the POS device 3 debits the remaining refueling fee from the credit card 5 in step S25, and transmits the debited amount together with the credit card 5 data to the card company center 6. Thus, the center 6 subtracts the debit amount from the balance in the user's bank account. When the remaining refueling fee from the credit card 5 is deducted, the POS device 3 instructs the card terminal 1 to return the credit card 5. As a result, the CPU 11 of the card terminal 1 controls the reader / writer 14 in step S26 to discharge the credit card 5 taken into the card insertion slot.

As described above, the self-refueling system can refuel using the credit card 5. When the remaining amount of the inserted magnetic card 4 is less than the unit amount of the selected oil type, the voice guidance is transmitted from the card terminal 1 to allow the user to insert the credit card 5 to permit refueling. Is completed, the refueling fee is first deducted from the magnetic card 4, and then the remaining refueling fee is deducted from the credit card 5, so that refueling by the magnetic card 4 becomes impossible even though the magnetic card 4 has a balance. That situation can be avoided. That is, even when the remaining amount of the magnetic card 4 is equal to or less than the unit amount of the selected oil type, the remaining amount of the magnetic card 4 can be used up by using the credit card 5 together.

In the present embodiment, the magnetic card 4 is used as a card used for refueling, but an IC card may be used instead of the magnetic card 4. Further, in the present embodiment, when prompting the user to insert the credit card 5, voice guidance is transmitted, but a beep tone may be sounded. Further, in the present embodiment, the insertion of the credit card 5 is urged when the amount of the magnetic card 4 is equal to or less than the unit amount of the selected oil type, but when the user desires to refuel, for example, 20 liters of high-octane gasoline. The amount of the magnetic card 4 is equal to the refueling fee (that is, the unit price of the selected oil type × 20).
(L), it is possible to similarly prompt the insertion of the credit card 5. Further, in the present embodiment, the selection of the oil type is performed at the card terminal 1, but may be performed at the measuring device 2. Further, in the present embodiment, the card terminal 1 and the measuring device 2 are provided separately, but the card terminal 1 and the measuring device 2 may be integrated.

Next, FIG. 5 is a flow chart showing another example of the operation of the self-refueling system, showing the operation when the used credit card 5 is discharged. That is, when the refueling fee for the credit card 5 inserted into and taken into the card terminal 1 is deducted, the CPU 11 of the card terminal 1 controls the reader / writer 14 in step S30 to transfer the credit card 5 to the reader / writer. 14 from the card insertion slot. In this case, the CPU 11 starts the built-in timer 11A for a predetermined time in step S31, and controls the voice synthesis IC 19 to transmit a beep tone from the speaker 21 in step S22.

When the user removes the credit card 5 by the beep tone that prompts the user to remove the credit card 5 from the card insertion slot, the removal of the card is detected by a sensor arranged near the insertion slot. Is transmitted to in this case,
The CPU 11 determines "Y" for "card removal?" In step S33, stops the timer 11A in step S35, stops the beep tone in step S36, and ends the process.

If the credit card 5 is not removed from the insertion slot, the beep tone is sent out in step S32 after "N" of "timer timeout?" In step S34, so that the beep tone is sent out continuously. ing. If a predetermined time has elapsed in such a state and the timer 11A has timed out (timed up), the determination in step S34 becomes "Y".
Stops the timer 11A in step S37, stops the beep tone in step S38, and controls the reader / writer 14 in step S39 to reload the credit card 5 into the card reader 14.

Then, in step S40, the POS device 3 is notified of the card reloading together with the card data.
In the POS device 3 which has received the notification of the internal take-in of the credit card 5, the POS device 3 informs the center 6 of the card company which issued the credit card 5 of the information indicating that the card has been forgotten in step S41 and the data of the card 5, Along with the name of the stand where the card has been reloaded and the card terminal number will be notified. In this case, the card company center 6 displays and prints out the data notified from the POS device 3, and in step S42, the card company operator notifies the corresponding user of the forgotten card by telephone. . Here, the center 6 of the card company
When the information indicating that the credit card 5 has been forgotten is received from the POS device 3 together with the card data of the credit card 5 or the like, the telephone number of the user included in the card data included in the card data is automatically transmitted in step S42 after a predetermined time. When the user responds, a voice signal stating "The credit card that you have forgotten is stored in the card terminal of the XX stand. Please enter the card PIN in the card terminal and receive it." By transmitting the information, it is possible to automatically notify the user who is the owner of the credit card 5 of the information that the credit card 5 has been forgotten.

When the user is notified by the card company that the card has been forgotten, the user goes to the stand and operates a ten-key (not shown) in the operation unit 17 of the corresponding card terminal 1 so that the user can use his / her own credit card in step S43. Enter your PIN. Then, the CPU 11 of the card terminal 1 determines in step S44 whether or not the password input by the user matches the password in the card data stored in the credit card 5 that has been retaken. Is detected and the determination in step S44 becomes "Y", the credit card 5 incorporated therein is returned by controlling the reader / writer 14 in step S45. As described above, since the credit card that the user has left behind after refueling is taken into the inside of the card terminal 1, it is possible to reliably prevent the credit card from being stolen by a third party. The credit card taken into the card terminal 1 can be received by inputting a personal identification number.

When the center 6 of the card company receives the information indicating that the credit card 5 has been forgotten from the POS device 3 together with the card data of the credit card 5, the center 6 of the card company includes the personal information of the user included in the card data. Based on the information, it is determined whether or not the mail address of the user is registered in the center 6. If the mail address of the user is registered in the center 6, the user is notified by e-mail that the credit card 5 has been forgotten. Information to the effect can be automatically notified. In this case, the user receives the e-mail notified from the card company, and similarly goes to the corresponding stand from the content of the received e-mail and inputs the personal identification number of his / her credit card to the corresponding card terminal 1, so that the user who has forgotten his / her personal information can be obtained.
