Description

Self refueling automatic payment system

The present invention utilizes various types of cards (for example, credit cards, debit cards, prepaid cards, etc.) and cash using various information recording media such as magnetic stripe (MS), high frequency (RF), and IC (IC). The present invention relates to a self-fueled automatic payment system that enables a user to set a desired oil supply amount without the help of a gas station service agent, and to make an automatic payment by calculating an amount for the final oil supply amount when oil supply is completed. .

In general, cards issued to meet consumer demand by various financial institutions, such as banks and credit card companies, are classified according to a method of paying a transaction price, and a credit card that pays a transaction price later and a bank It can be divided into a debit card that pays the transaction price at the same time as a transaction by transferring from a designated account, and a prepaid card that subtracts and pays the transaction value from the predetermined amount whenever a transaction occurs after a certain amount is paid in advance. The cards may include a magnetic card using a magnetic strip (MS) according to a medium for recording card information, an IC card that mounts an IC chip on a card, and programs or reads card information by direct contact with an IC pin; An IC chip and a high frequency (RF) antenna are mounted to show a high frequency (RF) card for programming or reading card information in a non-contact state with the card.

Recently, oil refiners and oil companies have introduced self-lubrication systems to increase the sales of petroleum and standardize their services.However, delays in the development of payment terminals to cope with this delayed the expansion of services for self-oiling systems. .

For example, the conventional self-fueling system is limited to cash and credit card, so users who want to self-fuel have a lot of inconveniences because they can use the oil dispenser only when they have a cash or credit card. There is an inherent factor in delaying time in order to secure the promptness required for service.

That is, when using a credit card terminal embedded in a gasoline unit or attached to an out door terminal (ODT), the credit card number and the amount of money read on the card terminal are transmitted through a communication line (regular telephone line or leased line) connected to the card issuer. If the card issuer or value-added network operator checks the credit status, usage level or bad transaction of the credit card and transmits the authorization number to the card terminal when there is no abnormality, the transaction is made. There was a problem that takes a lot of time (seconds to tens of seconds).

In the case of using cash in the self-lubrication system as described above, there was a possibility of theft of cash stored in the gas tanker, and therefore, there was a problem that a large amount of money was required when introducing equipment to prevent cash theft. In contrast, the use of precise equipment raises the disadvantage that the cost increases rapidly, which is an obstacle to the introduction of the unmanned fueling system that is recently spreading.

Therefore, the present invention was created in order to solve the above problems, the present invention is the user's own by using a variety of payment means, such as different types of cards, cash, etc., each of the personal information recording medium of the card, each different payment method By refueling the refueling system and automatically processing the amount converted from the final refueling amount, thereby eliminating the possibility of fraudulent use that may be caused by leaving the card to the refueling agent when the payment is made by the card. It is an object of the present invention to provide a self-fueling automatic payment system that allows a gasoline system to be freely used even when a gas station is insufficient at a gas station or when service is not available at night.

In order to achieve the above object, the present invention provides a number of setting means for providing a plurality of numeric keys and function selection keys to arbitrarily select the type of payment means or oil supply method (quantitative oil supply or fixed amount oil supply) according to the user's intention; Display means for displaying a key operation state of the setting means necessary for oiling and payment or for displaying service information regarding an operation state of the device according to the key operation; Cash recognition means provided with a bill insertion slot at a predetermined position in the vicinity of the setting means and the display means, and a bill reader capable of recognizing the bill inserted into the bill insertion slot; A card insertion slot for inserting a card into a predetermined position near the cash recognition means is installed, and a card viewing window for sensing a high frequency (RF) card within a predetermined distance, and a magnetic strip (MS) or a chip ( A magnetic card reader, an IC card reader, or a radio frequency (RF) card reader capable of accessing a card using an IC) as an information recording medium is provided inside the card slot and the card viewing window.

The card selection result can be recognized. When the card is set among the cash / cards, the card types classified according to the information reading method (for example, MS card or IC card read card information by direct contact, and RF card read card information by non-contact) Therefore, it is possible to reconfigure the input / pass card) so that the card can be programmed to drive the corresponding reader of each recognition means. In this case, the first step may be programmed to omit the step of setting the type of payment means and to always check that the payment means is inserted or passed by always operating the bill recognition unit and the plurality of card recognition units.

In the second step, when the type of payment method is recognized as cash in the first step, the face value or the damaged state of the bill is read and inquired, and if the inquiry result is not a valid bill, it is indicated that the bill is unavailable. After the bill is returned, the bill is reset to an initial state. If the bill is valid as a result of the inquiry, the billed amount or oil supply is output to the display means to display text, graphic or voice service information. In the first step, when the type of payment method is recognized as an MS card, an RF card, or an IC card, the card information is read and inquired off-line via SAM, or on-line through a modem. Check with the network operator and check the card type, usage status, credit and bad transactions according to the payment method. If the card is invalid as a result of the check, the card is displayed in a defective state and returned to the initial state after the card is returned.

In the third step, when the valid banknote is put in, the oil supply port permits oil supply so that the flow rate corresponding to the face value is lifted and the nozzle is lifted or the switch is turned on. The operation is started and the oil supply is started. This operation proceeds until the oil supply liquid is equal to the set liquid to accumulate oil supply amount. At this time, when the oil supply amount and the set amount are the same, the nozzle switch is turned off automatically. On the other hand, in the case of a valid card, the user can select the desired oil supply method (e.g., fixed quantity, fixed amount, full fill) in the display state, and if the fixed quantity / fixed amount of oil is selected, the desired amount of oil supply or oil amount is set again. (If lubrication is selected, lubrication is set. If sperm refueling is selected, lubrication can be started.) When lubrication is completed, turn off the nozzle switch automatically. If the quantitative / settled lubrication is not set in the lubrication mode selection step, the lubrication is recognized until the fuel tank is filled, and lubrication is started according to the opening and closing operation of the nozzle switch and the nozzle latch, and lubrication is performed when the nozzle latch is automatically turned off. To complete.

In the fourth step, when the fueling is completed, in the case of cash payment for each payment means obtained as the result of the inquiry, the amount of the transaction made in the gas tanker is immediately issued and reset to the initial state. If the payment method is a debit card, the transaction amount is automatically transferred on-line from the designated account, the payment is issued, the card is returned and the initial state is reset. If the payment method is a prepaid card, the transaction amount is subtracted from a certain amount of money remaining on the card, the payment is made offline, a payment transaction receipt is issued, the card is returned, and reset to an initial state. If the payment method is a credit card, the transaction amount is credited, a payment transaction receipt is issued, the card is returned, and reset to an initial state.

According to the present invention as described above, not only a magnetic card but also an IC card or a high frequency card is applied to a self-lubrication system, and a SAM (security access module) is installed in a payment terminal, and if necessary, the credit card of the card by the off-line method is used. Also, by checking whether or not a bad transaction is confirmed, it minimizes the possibility of fraudulent use, prevents service delays that may occur in the existing on-line method, and currently uses credit cards, debit cards, prepaid cards, By checking the payment terminal directly in the field by various payment methods such as cash, it is possible to exclude the possibility of misuse which may occur when the card is left to the petrol station, and at least when the service of the petrol station is not available, such as at night. Operation of the self-lubrication system to free oil supply and payment Be executed, and the user provides the service for the operation of each step in response to the operation of the self-checkout process, the oil supply to the lubricators by voice and graphics, so there is an advantage that facilitates the operation by the user.
