JP4929219B2 - Sales system using contactless prepaid card - Google Patents

Description

  The present invention relates to a sales system using a non-contact prepaid card that enables settlement when purchasing a product or the like by using a non-contact prepaid card in a merchandise store or the like. In particular, the present invention relates to a sales system characterized by change processing that takes into account the convenience of handling a customer's contactless prepaid card in a commercial transaction using the contactless prepaid card.

  In recent years, cashless commercial transactions, that is, commercial transactions in which payment is made for purchases of goods and the like without delivering cash, have become widespread.

  One of the cashless business transactions is a credit card sales system. Such a credit card business transaction is a mode in which the user purchases a product or the like by credit on the condition that the user has a deposit account, and later completes the settlement by withdrawing the purchase equivalent amount from the user's deposit account.

  There exists a mode which uses a prepaid card as a 2nd sales system. The customer purchases a prepaid card holding a predetermined amount of the initial balance that can be traded with cash or credit, and the prepaid card enables the purchase of the product within the balance deducted each time the product is purchased. It is an aspect.

  As another mode of using a prepaid card, there is an additional prepaid card system in which the balance of the prepaid card can be added (additional charge) by cash advance payment by a user or postpay by credit in a timely manner.

  The additional type prepaid card system is further in contact type that allows the payment facility to be magnetically contacted to read and update the balance, and non-contact type that allows the balance to be read and updated without contact. Classified as a prepaid card system.

  In a system that uses a non-contact type prepaid card, the user can read and update data by bringing the pre-paid card close to the reader in a non-contact manner. Can be given. From this point of view, a system using a non-contact prepaid card is spreading in various fields.

  FIG. 1 is a flowchart showing an example of a clearing procedure in a fueling system using a contact type prepaid card that allows a balance to be read, written and updated by magnetic contact at a gas station.

  The customer first selects a payment method (step S1). When selecting a prepaid card (hereinafter abbreviated as “preca” as appropriate), the prepaid card is inserted into the reader (step S2).

  Next, the oil type is selected (step S3), and the amount of oil supply or the amount of money is designated within the limit of the precica balance (step S4).

  Thereafter, a refueling operation is performed (step S5), and the refueling operation is terminated (step S6).

  The refueling machine cooperates with the POS device, determines the refueling amount from the refueling amount and the unit price at the end of the refueling operation, subtracts the refueling amount from the prica balance, updates it to a new balance, and writes update data to the prica ( In step S7), the precursor is released from the card reader (step S8). At the same time, a receipt is output (step S9).

  In a transaction using such a contact type precursor, the precursor is inserted into the card reader (step S2), the transaction is settled, the balance is settled, the precursor balance is updated (step S7), and the precursor is released (step S2). The precursor is held in the apparatus until S8).

  On the other hand, in the case of a system using a non-contact type prica, as shown in FIG. 2, the payment method is selected (step S1), and instead of inserting the prica (step S2: FIG. 1), the customer is non-contact While holding the precursor itself over the reader, the data of the non-contact precursor is read, and the authenticity of the precursor is confirmed and the purchaseable balance is confirmed (step S2A).

  Next, an oil type is selected (step S3), and an oil supply amount or an amount is designated (step S4). Thereafter, a refueling operation is performed (step S5). When the refueling operation is completed (step S6), the refueling amount corresponding to the refueling amount is subtracted from the previously read prepay balance data, and the balance is updated (step S7).

  At this time, it is necessary to reflect the updated balance in the corresponding prefix. For this reason, the customer needs to hold the non-contact precursor on the reader again (step S8A) and write the updated precursor balance into the precursor. When the update record of the prepay balance data is completed, a receipt is output (step S9).

  As described above, when the transaction procedure using the non-contact precursor is applied in correspondence with the transaction procedure of the contact-type precursor shown in FIG. 1, the customer brings the non-contact precursor to the reader twice as shown in FIG. Is required (steps S2A, S8A).

  However, taking out the pre-cursor once stored therein and accessing the reader again detracts from the convenience of the non-contact pre-curer for the customer.

  Under such circumstances or with a non-payment intention, it is sufficiently assumed that the customer leaves the refueling machine without performing the clearing process after the refueling is completed.

  That is, the customer (1) holds the card for checking the balance before purchasing the product, and (2) holds the card again after receiving the product to withdraw the purchase amount. In product sales, if the customer performs these series of actions, it is cumbersome to hold it twice, and if the action (2) is not performed, (3) the price cannot be collected. Problems arise.

  In order to solve the problem (3), for example, the invention described in Patent Document 1 has been proposed.

  The outline of the invention described in Patent Document 1 will be described as follows.

  FIG. 3 is a flowchart for explaining the processing procedure of the invention described in Patent Document 1 by taking a self-service gasoline refueling as an example, and as a feature, before purchasing a product (gasoline), before refueling the customer with gasoline. It has a feature in that all the balances of Prica are withdrawn.

  That is, in FIG. 3A, the precursor data is read (step S10), and whether or not the precursor is authentic is verified by the password input by the user (step S11).

  Next, if the precica is usable, all the balance amounts recorded in the precica are acquired (withdrawn), the prica balance is updated to zero (step S12), and the refueling amount corresponding to the acquired precica balance is set. Refueling is permitted as a limit (step S13).

  Thereby, refueling is performed (step S14). When refueling is completed (step S15), a receipt recording the amount of refueling is issued (step S16).

  The balance after refueling is stored and held in the sales device (POS device) with the recorded balance set to zero (step S17).

  On the other hand, when the user confirms the balance after refueling from the issued receipt, as shown in FIG. 3 (B), when he / she wishes to return the balance, he / she reads the pre-cursor information again to the deposit addition device (charge device). (Step S18).

  The charging device inquires of the POS device about the balance of the corresponding replica based on the prefix information (step S19).

Therefore, the balance obtained in response to the inquiry is written in the prepa, or cash corresponding to the balance is paid out (step S20).
JP 2006-331099 A

  As described above, in the invention described in Patent Document 1, it is necessary to once set the balance of the plica to zero in order to give a fueling permission. For this purpose, the user needs to hold the plica over the reader until the balance is updated to zero. Alternatively, it is necessary to perform two readings at two timings, that is, the timing for authenticating the precica (step S11) and the timing for updating the balance to zero (step S12).

  Further, in general, a gas station is often provided with a store for selling related products together with a fueling device. However, in the invention described in Patent Document 1, in order to once set the balance of the plica to zero, if the balance corresponding to the change is not written (step S20) after the end of refueling, the record balance of the prec Has a disadvantage of being unable to receive additional services such as product purchases at the store or car washing.

  The above-described aspects and inconveniences have a problem of impairing convenience in using the customer's precica.

  Furthermore, in the invention described in Patent Document 1, although there is a description of the common use of the replica between a plurality of stores, there is a communication failure in the exchange of balance data between a plurality of stores, or the payment balance data is erased. If there is a failure at times, there is a possibility that multiple balance payments will be made, which is disadvantageous for the store side, and at the same time, there is a problem that the trust to the customer is impaired.

  Therefore, the object of the present invention is to use such a non-contact type preca, without losing the convenience of the customer's preca An object of the present invention is to provide a sales system using a non-contact prepaid card corresponding to both theft prevention and the later change payment accident prevention.

  The present invention for solving the above-mentioned problems is a non-contact prepaid card owned by a customer in a sales system that uses a non-contact prepaid card in a sales form such as a product whose quantity and amount of sales are not fixed until the end of the sales act. The card information data including at least the identification ID for identifying the contactless prepaid card and the product purchase balance recorded on the card is read by a contactless precursor processor, and the purchase schedule designated by the customer by the POS device An equivalent amount is withdrawn from the product purchase balance of the non-contact prepaid card, and supply control of the product etc. up to the planned purchase equivalent amount withdrawn by the POS device is performed by a product sales machine, and the product is further controlled by the POS device. The difference between the planned purchase equivalent amount and the actual supply amount with the end of supply control such as Qian amount calculated, wherein when re-reading the card information data of the non-contact prepaid card by the non-contact replica processor, and wherein the pay by adding the change amount to the balance of the prepaid card.

  The first feature of the present invention is that the equivalent amount to be purchased is deducted from the product purchaseable balance, and at this time, the customer can make another use of the contactless prepaid card within the range of the balance.

  Further, as a second feature, in order to ensure payment of change according to the first feature, the card information data further includes a change number that is incremented each time the change is paid, The non-contact prepay processor can be configured to add the change amount stored on the POS device side to the remaining amount of the non-contact prepaid card corresponding to the identification ID.

  Further, as the third feature, under the second feature, the card information data further includes a sales serial number that is incremented each time the equivalent amount to be purchased is deducted from the product purchase balance of the contactless prepaid card. When the change serial number recorded on the non-contact prepaid card and the sales serial number are the same, it is determined that the change has been paid. When the change serial number is smaller than the sales serial number, the identification ID It is possible to add the unpaid change amount to the remaining amount of the non-contact prepaid card corresponding to.

  In addition, as a feature, the contactless prepaid is used as preference data on the history data of the previous product purchase or the combination of the product at the time of purchase by the product purchaser in order to simplify the product designation input at the time of product purchase by the customer. Register in addition to the card information data of the card. Then, when the customer purchases the product, the history data and / or preference data is displayed, and the purchase corresponding to the history data or preference data selected by the customer within the range of the balance of the prepaid card. Product specification is possible.

  According to the present invention, one or a plurality of products / services can be purchased without impairing operational convenience for a customer who uses a non-contact precursor (while refueling automobile fuel at the gas station). Payment can also be made in parallel with the purchase of kerosene, and payments can be refunded correctly to customers who use multiple stores, and the store can prevent losses due to customer fraud. A system is realized.

Embodiments of the present invention will be described below with reference to the drawings.
In the following, a non-contact prepaid card will be simply abbreviated as “precard”.

  FIG. 4 is a block diagram of an embodiment of a self-service gas station to which the present invention is applied. In the following description of the embodiment, a self-service gas station that sells fuel oil exclusively as a product will be described. However, prior to sales, a sales system that specifies a customer's planned purchase amount / amount in advance. For example, the application of the present invention is not limited to such a self-service gas station.

  In FIG. 4, a plurality of stores 1 </ b> A and 1 </ b> B (two stores A and B are shown as an example in FIG. 4) that can use the same replica are connected to the data center 2. Since stores 1A and 1B have the same configuration, they are simply referred to as store 1 hereinafter.

  The store 1 has a sales management device (POS device) 10, a refueling facility 11 that is a merchandise sales machine connected thereto, a non-contact prepaid card reading data and a non-contact prepaid card writing processing function The non-contact precuring processor 12 having the above and the settlement machine 13 are included.

  Here, in the embodiment shown in FIG. 4, one store 1 is shown with a fueling facility 11, a non-contact precurler processing machine 12, and a checkout machine 13 one by one. It is not limited.

  The checkout machine 13 is normally used as a change payment machine in cash sales. However, by incorporating or adding a non-contact precica processing function here, additional payment (charge) or change prepa according to the present invention to be described later can be added. It is a device that performs refund processing by writing and setting preference data.

  In one store, a plurality of merchandising machines, a refueling facility 11, a non-contact precursor processor 12, and a checkout machine 13, are connected to the POS device 10 by wire or wirelessly using an in-store communication line or a LAN (hereinafter, referred to as a “store” These are simply connected through signal lines, and are identified by the machine number in the POS device 10.

  A server 20 is provided in the data center 2 connected to each store via a communication network such as the Internet. In the figure, the data center 2 is shown separately from each store 1, but the server 20 may be arranged in any store.

  In addition, the oil supply facility 11 and the non-contact precursor processor 12 in one store can be configured as a single housing unit that is compatible with the oil supply pump.

  FIG. 5 is a diagram for explaining a product purchase procedure using the pre-cursor in the embodiment of the self-type gas station shown in FIG.

  FIG. 6 is a diagram for explaining a data flow between the non-contact precursor processor 12 and the POS device 10 in the product purchase procedure of FIG.

  The customer goes to the fueling facility 11 which is a merchandise vending machine, selects and inputs a payment method (step S100). This payment method selection (step S100) is performed by the customer manually inputting from a selection input means arranged in the fueling facility 11. Alternatively, it is also possible to input the payment by the precica as a payment method by holding the precica over the non-contact precica processor 12 and reading the information of the precica.

  Next, the oil type is selected (step S101), and the oil supply amount or the amount of oil supply, that is, the product purchase planned amount is input (step S102). Next, the customer performs a settlement process by holding the replica over the non-contact replica processor 12 (step S103).

  The first feature of the present invention is that the settlement processing is performed based on the planned purchase amount as described above.

  In addition, as a method for specifying the amount of oil to be supplied or the amount of fuel to be supplied, it is possible to specify “full tank”, which means the amount of oil supplied until the oil can be supplied to the so-called fuel tank of the vehicle. In such a case, it is also possible to control the fuel supply facility 11 so as to enable the option of setting the entire remaining amount of the prepa or a predetermined amount of oil supply, for example, 50 liters.

  The settlement process (step S103) will be further described with reference to FIG. The non-contact precursor 12 reads the prepa card information data 100 (indicated as “preca internal data” in FIG. 6) read from the precap, the card identification ID, the product purchase balance (hereinafter simply referred to as balance data). , And a “fishing serial number”.

  The present invention uses the “fishing serial number” as a second feature to realize reliable payment of fishing. In the example shown in FIG. 6, the initial value is set to “1”. The change number is a numerical value that is incremented when the change payment process is performed.

  The internal data of the printer read from the printer is sent to the POS device 10 through a signal line. At this time, the designated value of the oil type, the amount of oil supply, or the amount of oil supply specified to the oil supply facility 11 is sent to the POS device 10.

  Accordingly, the POS device 10 performs settlement processing by subtracting the planned refueling amount corresponding to the specified amount of refueling from the balance data read from the precharger, and calculates updated balance data.

  These updated balance data are sent to the non-contact precursor processor 12 through the signal line as updated balance data (processing step P1). Thereby, the non-contact precursor processor 12 writes and updates the update balance data sent from the POS device 10 to the precursor.

  Accordingly, the balance of the updated in-precursor data 101 is updated. In other words, the data written in the replica in the state in which this settlement processing is completed is as shown in data 101 in FIG. 6, the machine ID of the replica is xxxx, the updated balance is 8,000 yen, the change serial number 1 It is.

  When the writing of the updated in-precursor data 101 to the replica is completed, this is notified to the POS device 10 (processing step P2).

  When notified of completion of writing of the updated balance data to the replica, the POS device 10 finalizes the settlement process and stores the card information data and the scheduled refueling amount (pre-deduction amount) corresponding to the identification ID of the prefix (processing) Step P3).

  Returning to FIG. 5, when the settlement process is performed, the refueling operation becomes possible (step S <b> 104), and the refueling up to the designated refueling amount or the designated amount can be performed. When the refueling is completed with the refueling specified amount or the specified amount as a limit (step S105), the POS device 10 calculates a refueling fee based on the actual refueling amount notified from the refueling facility 11.

  The calculated fueling fee is notified to the fueling facility 11. The refueling facility 11 outputs a receipt that gives out the refueling fee (step S106), and the refueling process ends.

  An example of the receipt output here will be described later with reference to FIG. If no change occurs, the process ends here.

  At this time, when the refueling is terminated in the middle without refueling to the refueling specified amount or the specified amount, there is a difference between the scheduled refueling amount deducted in advance and the actual refueling fee, that is, a change amount. . Therefore, the POS device 10 generates change data 102 (FIG. 6 processing step P5) when change occurs after the sale ends (FIG. 6 processing step P4).

In FIG. 6, as the change data 102, the change amount of the prica whose identification ID is xxxx is 500 yen, and the POS device 10 holds that the change number is 1 The refueling facility 11 is settled by the POS device 1 when refueling is completed. Based on the received data, the fuel supply facility 11 issues a receipt (step S106). When issuing this receipt, a message for notifying the customer of the change is written on the receipt to notify the customer of the change amount.

  FIG. 7 is a diagram showing an example of the receipt issued in step S106 in FIG. FIG. 7A is a diagram showing a slip (receipt) when no change has occurred, and FIG. 7B is a diagram showing a receipt when change is occurring.

  That is, in FIG. 7 (A), no change occurs because the deposit amount is 2,000 yen and the gasoline price for refueling is 2,000 yen. In FIG. 7B, since the deposit amount is 2,000 yen and the gasoline price for refueling is 1,500 yen, a change amount of 500 yen is generated. In this case, a message notifying the customer of the presence of change (in the example shown in FIG. 7B, “The above payment amount has been deposited. Refund can be made again within 5 minutes after issuing this slip. Will be returned or will be returned at the next use of the settlement machine of our affiliated SS ").

  Returning to FIG. 5, when a change occurs, the amount of change that has been generated can be received by holding the non-contact pricker over the checkout machine 13 (step S107).

  The method of receiving the change amount will be described again in detail later, but it can be received by adding it to the balance of the prica. Further, when the change amount is settled in this way, the “change serial number” is incremented as will be described later.

  In order to receive the change after holding the non-contact precursor 12 in order to read the information data of the non-contact precursor in step S103, until the recap is held over the non-contact precursor 12 (step S107) At hand of customer. Therefore, as a first feature of the present invention, it is possible to use the pre-cursor used here in the range of the balance for the purchase of other products or services even during the period from step S103 to S107.

  Further, in FIG. 5, if the change receiving process is not performed within a predetermined time (for example, 5 minutes indicated in the receipt message), the change data is sent to the server 20 (not shown) and the other occasion. Can be received at the clearing machine 13 including the other stores (step S108).

  According to this embodiment process, in the sales system using the non-contact prepaid card, the store side does not process the collection of the price from the customer after the sale of the product to the customer, thereby causing no disadvantage.

  On the other hand, for the customer side, as described above, it is possible to purchase other products or services within the range of the balance even during the purchase of one product, and if there is change, the change is reflected immediately after the transaction. You can also In addition, since the change amount is stored in the POS device 10 or the server 20 in association with the identification ID of the plica, the change amount can be reflected in the prepa later. According to the embodiment of the present invention, commercial transactions having the convenience of a contactless prepaid card can be performed on both the store side and the customer side.

  FIG. 8 illustrates the processing when change is received at the gas station within a predetermined time (for example, 5 minutes) after the end of refueling, corresponding to the processing procedure of FIG. FIG.

  6, change data display C is further performed in FIG. 8, but change data recorded and held in the POS device 10 or recorded and held in the server 20 is shown. Here, for simplification of explanation, only one piece of data is shown, but actually, there may be a plurality of data in which a change number and a change amount are combined corresponding to a plurality of pre-IDs.

  If the customer holds the pre-cursor over the non-contact pre-curing machine 12 within a predetermined time (for example, within 5 minutes) after the sales slip is issued, the card information data read from the non-contact pre-curing machine 12 (FIG. 8, 101) (Prika IDxxxx, balance 8,000 yen, change serial number 11) is sent to the POS device 10 (processing step P6).

  The POS device 10 searches the stored change data 102 corresponding to the prefix ID xxxx and the change serial number 11 based on the card information data 101 sent from the non-contact prefix processor 12, and the change amount corresponding to the prefix ID is obtained. (Processing step P7).

  As a result, the POS device 10 updates the balance by adding the change amount (500 yen) of the change data searched in correspondence with the prefix ID xxxx and the change serial number 11 to the balance of the card information data 101 read earlier. Generate balance data. At this time, the fishing sequence number is incremented by 1, and the fishing sequence number is updated to 12. Then, the updated balance data is sent to the non-contact precursor processor 12 (processing step P8), and the card information data of the precursor is updated (processing step P9).

  Alternatively, when the change amount is notified to the non-contact precursor processing machine 12, the prepay balance is updated by the non-contact precursor processing machine 12 based on the change amount, and further the change number is incremented, and the updated balance Is generated (processing step P9). Then, the card information data 103 generated by the non-contact precursor processor 12 may be updated and written to the precursor. In this way, the POS device 10 and the non-contact precursor 12 need only generate card information data to be updated together, and the present invention does not limit the division of roles in the following description. Absent.

  Next, when the POS device 11 is notified by the non-contact precursor processor 12 that the update to the precar has been completed, the returned change data 102 is erased (processing step P10), and the change processing is completed. .

  Note that the same processing can be performed even when the customer holds the card over the checker 13 (in the case where the non-contact precurer processing function is incorporated or provided as described above) instead of the noncontact precurer processing machine 12.

  Here, in the above embodiment, the reason why the change serial number is adopted is to prevent the same change from being paid again when the payment has already been made as described above.

  That is, in FIG. 8, the POS device 10 searches the stored change data 102 corresponding to IDxxxx based on the identification ID in the card information data 101 sent from the non-contact precursor processor 12, and uses the identification ID and the change number as the identification ID. Corresponding change data is obtained (processing step P7).

That is, the change number in the card information data 101 is compared with the change number of the saved change data 102, and only when the numbers match, the change can be paid. If the card information data 101, if the tail fishing serial number is less change data 102 which is present, in which the previous change payment processing, even though the payment of the change has been performed for plica This means that the change data has not been processed for some reason on the system. In this way, double fishing payment is avoided by adopting the change number. The change data 102 for which payment has been completed is deleted (processing step P10).

  In the second feature of the present invention, which uses a change serial number, it is desirable that change data is managed in an integrated manner. As described above with reference to FIG. 4, when there are a plurality of stores that allow the same Prica to be used separately, the change data is distributed to the plurality of stores by communication, and each change store is used by using the change data. In the case where the change can be paid in the case, some change may not be paid correctly.

  As an example, if there are multiple change data for the same change number (that is, no change has been received even though multiple changes have occurred for multiple purchases) Consider a case where there is a store in which some change information is missing due to a communication failure in distribution from the center 2 to each store.

  When the customer tries to receive the change of the purica at the store holding the missing data, only the change data not missing at the store is paid and the change number of the purica is also advanced. That is, the remaining change data for the same change number loses the opportunity to be paid because the change number is no longer current. In order to avoid such a situation, when there are a plurality of stores, change data is distributed from the data center 2 to each store, and change payment processing is performed using the change data stored in each store. Instead, it is desirable to manage the change centrally in the server 20 of the data center 2 and acquire change data by an inquiry whenever necessary to perform change payment processing.

  Next, in the third feature of the present invention, in addition to the change serial number, a sales serial number that is a parameter that is advanced when the planned purchase amount of the product is deducted from the balance is used. By using such a sales serial number, for example, when there are a plurality of stores of the same series separately and each of them shares change data, there are multiple product purchase opportunities, and change is generated each time change occurs. Although communication of data is necessary, even if there is data loss during the communication, change can be surely returned and double payment can be prevented. It is also possible to easily determine whether or not the latest change refund processing for the prica has already been completed.

  FIG. 9 is a flowchart for explaining the progression of the sales serial number. This will be described in correspondence with the processing of FIGS.

  At least identification ID, product purchase balance, sales serial number, and change serial number are recorded as card information data in the plica. The change data on the POS device side (including the data center side) also includes at least the precica identification ID. The sales serial number and change amount are stored.

  In FIG. 5, after the non-contact prepaid card is selected in the selection of the payment method (step S100), the selection of the oil type (step S101), the refueling amount or the amount is designated, and the product purchase planned amount is input ( Step S102). The card information data, which is the internal data of the replica, is read by the non-contact precursor processor 12 by the processing of holding the replica (step S103). In the read card information data 201, in the example of FIG. 9, the identification ID of the replica is xxxx, the balance of the prefix is 10,000 yen, and the sales serial number 1 and the change serial number 1 are assigned as initial values.

  9 is sent to the POS device 10 (processing step P10).

  Based on the identification ID of the card information data 201, the POS device 10 determines whether or not the plica is genuine, and if it is genuine, based on the selected oil type and the designated oil supply amount or amount, The planned refueling purchase amount (2,000 yen in the example of FIG. 9) corresponding to the specified refueling amount is obtained from the prica balance and subtracted from the balance in the card information data 201 to update the balance. At this time, the sales serial number is updated (step 1 is incremented to 2), and the record is held (processing step P11). Then, the updated balance and sales serial number are notified to the non-contact precuring machine 12 (processing step P11A).

  Based on this notification, the non-contact precursor processor 12 writes the notified update balance and the updated sales serial number to the replica as update data. Therefore, the updated internal data of the replica is the contents of the card information data 202. That is, the balance is changed to 8,000 yen, and the sales serial number is incremented to 2.

  When the update data is written in the prefix, the update completion is notified to the POS device 10 (processing step P12). When notified of the completion of the update, the POS device 10 sends a refueling permission signal that limits the designated refueling amount / amount to the refueling facility 11.

  Next, when refueling is completed, the refueling facility 11 notifies the POS device 10 of the end of refueling sales and the actual refueling amount.

  When notified of the end of refueling, the POS device 10 calculates the actual refueling amount based on the actual refueling amount, and calculates the difference from the previously deducted amount of 2,000 yen, that is, the change amount (processing step P13). The example in FIG. 9 is also an example in which the actual refueling amount is 1,500 yen and the change amount is 500 yen.

  The POS device 10 generates change data 203 based on the calculated change amount, and records and saves it in the POS device 10 or the server 20 corresponding to the card identification ID (processing step P14). The change data 203 includes information of a card identification ID xxxx, a change amount 500, and a sales serial number 2.

  FIG. 10 is a diagram for explaining the use of the sales number described in FIG. In particular, it is a sequence flow for explaining change processing when there are a plurality of stores and there are a plurality of product purchase opportunities.

In FIG. 10, based on change data corresponding to a plurality of merchandise purchase processes as change data, the sales data number and change amount are registered in the change data table 300 corresponding to the identification ID. In the example shown in FIG. 10, it is assumed that there was a total of two product purchase transactions of 1,000 yen after that of FIG. 9, sales serial numbers 2 and 3 corresponding to the same identification ID xxxx and change amounts corresponding to them. 500 yen and 0 yen are registered. That is, even when the change amount is 0 yen, it is recorded in the change data table 300 corresponding to the sales serial number.

When there is a change return request from a customer (refers to an act of holding the precursor over the non-contact precursor processing machine 12 other than at the time of refueling reservation, or an act of holding a prepayer over the noncontact precursor processing machine 12 in step S108 in FIG. 5) , 10, non-contact replica processor 12 reads the card information data 204, and sends to the POS device 10 (step P20).

  The POS device 10 refers to the stored change data table 300 and searches for the change amount of the sales serial number that matches the identification ID and is greater than the value of the change serial number in the card information data 204. In the example shown in FIG. 10, sales serial numbers 2 and 3 that are both larger than the change serial number 1 are stored in the change data table 300. Accordingly, change amounts of 500 yen and 0 yen corresponding to these are obtained, and the total change amount of 500 yen and two cases are obtained. (Processing step P21).

  The POS device 10 notifies the information and the number (= 2) of the refund amount of 500 yen to the non-contact precuring machine 12 (processing step P22). The contactless precursor processor 12 adds the refund amount to the balance of the card information data 204 and sets the new balance to 7,500 yen. Furthermore, the change serial number is incremented by 2 based on the information on the number of cases (= 2), and is updated and recorded as 3 in the prefix (processing step P23). The card information data inside the plica is updated as shown at 206.

  Next, when the POS device 10 receives a notification that the preca has been updated, the POS device 10 erases the information of 500 yen and 0 yen of the change amount corresponding to the sales serial numbers 2 and 3 of the identification ID xxxx in the change data table 300. Performed (processing step P24).

  Here, the sales serial number in the updated card information data 206 matches the change serial number. In this way, when the sales serial number is equal to the change serial number, it means that all the change refund processing has already been completed.

  That is, as an advantage of the third feature of the present invention, it is possible to determine whether or not the latest change refund processing has already been completed only by comparing “sales serial number = change serial number” in the prefix when receiving change.

  In addition, since the change corresponding to the sales serial number (latest transaction) in the Prica is the change data having the same sales serial number, a non-contact Prica processing machine is built in the checkout machine 13, and the change data is held in this device. When the change is returned to the customer, it is possible to recognize whether or not the latest change data exists in the non-contact precuring machine itself. If the data center does not exist, for example, by processing the data center 2 to request the latest data, the amount including the latest change can be refunded even if there is no regular delivery from the data center 2. .

  Since the change serial number of the change data is continuous, even if the change data is distributed to each store, the lack of data is recognized by confirming the continuity of the change data sales number held in each store. it can. Therefore, the lack can be prevented by requesting the data center 2 to replenish the missing data.

  Further, even if the missing data cannot be replenished due to the inability to temporarily communicate with the data center 2, only the change up to the change number less than the change number of the missing data is returned and the change number is updated. Thus, it is possible to avoid a state in which no change is paid while preventing double change payment.

  In this way, when two parameters of sales serial number and change serial number are used, in a sales system in which a plurality of stores and a data center related to change data are connected via a network, change payment for transactions using a contactless prepaid card Can be ensured.

  For the change data change after payment has been completed, it is possible to confirm at least the continuity of the sales serial number, such as by providing a paid flag (not shown) instead of deleting it to confirm the continuity of the sales serial number. It is desirable to keep the data in a simple manner.

  Here, in the application of the present invention, during the change acquisition operation at the clearing machine 13 performed in step S107 of FIG. FIG. 11 is a processing flow of a processing procedure when it is possible to perform the change acquisition operation and the additional deposit processing at the same time.

  In FIG. 11, the customer holds the card over the clearing machine 13 and reads the card information data (including card ID, balance, change number, and sales number) (step S200). The clearing machine 13 determines whether the sales serial number matches the change serial number (step S201).

  If the sales serial number matches the fishing serial number (Yes in step S201), all the fishing payment processing has already been performed, so there is no change payment processing message (for example, there is no change in storage) ) Is displayed (step S202A).

  Further, an additional message for prompting additional payment (for example, the balance of the card is 8,000 yen. Do you want to make additional payment?) Is displayed (step S202B).

  For such an additional message, the determination of Yes or No is made (step S210).

  If No is designated (step S210, No), the process is terminated.

  If Yes is specified (step S210, Yes), the deposit amount is confirmed (step S211), and a deposit confirmation message (for example, a deposit of 10,000 Yen. The card balance is updated to 18,000 Yen) is displayed ( Step S212).

  Based on this message, the balance is updated when the prepay is held over the clearing machine 13 (step S213), and a transaction receipt is output (step S214).

  On the other hand, if the sales serial number is not equal to the fishing serial number in step S201 (No in step S201), there is uncleared fishing, so a message (for example, the card balance is 8,000 yen.) (The amount is being confirmed.) Is displayed (steps S203A and 303B).

  While the message is being displayed, the clearing machine 13 accesses the POS device 10 or the server 20 of the own store and acquires change amount data (step S204, message (for example, change amount is 500 yen. Additional payment) Is displayed (step S215).

  For such an additional message, the designation of Yes or No is determined (step S216).

  If No is designated (step S216, No), the price card is held over the clearing machine 13, the balance and change number are updated (step S213), and a transaction receipt is output (step S214).

  On the other hand, if Yes is specified for the message in step S215 (step S216, Yes), the deposit amount is confirmed (step S217), and a deposit confirmation message (for example, 10,000 yen is deposited. The card balance is 18,500). Is updated to a circle.) Is displayed (step S218).

  Based on the message, the balance and the change serial number are updated when the plica is held over the clearing machine 13 (step S213), and a transaction receipt is output (step S214).

  FIG. 12 is an example of the transaction receipt output in step S214 in FIG. 11, and is an example when there is change payment and additional payment.

  The prica balance, deposit change amount and additional deposit amount are recorded, and the total amount of these is recorded and output as an updated prica balance.

  Although the sales serial number and change serial number in the present invention have been described by taking decimal integers as an example, it is not limited to this as long as the time-series context can be determined. Other values such as hexadecimal numbers and constant promises are not limited thereto. Symbols based on items, circulation numbers up to a certain value (for example, 10000 then returns to 1), and the like can be used.

  In addition, in the change payment, only the method of adding to the prica balance is illustrated. However, when refunding with cash, the prica balance is not changed, and only the change serial number can be updated.

  Here, when purchasing a product, in general, the same product as the previous purchase may be purchased, or a specified product such as a combination of products may be purchased repeatedly.

  In such a case, even when a product is purchased using a pre-cursor, each time a product is purchased, the same repetitive input is required for purchasing the same product as the previous purchase or a specified product of preference.

  Therefore, the customer feels annoyed that impairs the convenience of using the prefix.

  The present invention can improve such inconvenience as an example. FIG. 13 to FIG. 15 are a series of process flow diagrams of an embodiment that eliminates the need for the same repeated input when purchasing the same product as the previous purchase or a specified product of preference.

  In FIG. 13, the customer selects a payment method in the fueling facility 11 (step S300). Assume that payment by contactless preca is selected in the selection of this payment method.

  In response to the selection of payment by the non-contact prica, the refueling facility 11 may, for example, “If you use preference data or the previous purchase history, check the balance of the card, if you want to make additional payment, first insert the card Please hold it over the pre-processor 12 ”(step S301).

  Here, the preference data or the previous purchase history is information set in advance by the customer or generated based on the latest customer transaction. For example, a table as shown in FIG. Registration is recorded.

  In the example shown in FIG. 16, data (information 1, 2,...) Relating to a product purchased last time corresponding to a service category (for example, refueling, car wash) is recorded in the previous purchase history record column I. For example, the previous purchase history data of “regular gasoline: 5,000 yen, wax car wash: lower car wash” is stored.

  Furthermore, a combination of favorite products set by the customer is recorded in the preference data recording column II. For example, combination data of “regular gasoline for refueling: 2,000 yen, coating car wash for lower car wash: with lower car wash” is recorded in the non-contact Prica as preference data.

  Here, the preference data is generated according to the processing flow shown in FIG. 17 as an example. FIG. 17 is a processing flow when “Preference data setting” (button is not displayed) is pressed instead of the payment method selection S100 in the fueling facility 11 in FIG. In addition, in the use in the settlement machine 13 (with or without a non-contact precurr processing function), it is a processing flow when “Preference data setting” (button is not displayed) is first pressed. .

  That is, in FIG. 17, after selecting the “favorite data setting” process, the data is read by holding the precursor over the non-contact precursor processor 12 or the checkout machine 13 (step S400).

The fueling facility 11 or the checkout machine 13 displays the following message based on the read “favorite data” (step S401).
“Message: Your favorite data” is as follows: Refueling: Regular gasoline 2,000 yen Car wash: Coating car wash Lower car wash Please press “Change” button to change, “Cancel” button to cancel. "
If “favorite data” has not been generated, instead of the indication “Fueling: Regular gasoline 2,000 yen, Car wash: Coated car wash, Lower car wash”, “Preference data is not registered.” Display is performed.

  In FIG. 17, the refueling facility 11 or the checkout machine 13 waits for an input of “change” or “cancel” after the display in step S401 (step S402).

  When “cancel” is input by pressing the “cancel” button (step S402A), the favorite data update process ends.

  When “change” is input by pressing the “change” button (step S402B), refueling preference data change acceptance processing (step S403) and car wash preference data change acceptance processing (step S404) are performed.

  In the processing of steps S403 and S404, the preference data is newly input or changed, and the customer newly holds the above-mentioned preference data that has been generated or changed as a result of the purchase of the prefix. The data is written in the designated area, that is, the preference data column II in the table of FIG. 16 (B2), and the process is terminated.

  Returning to FIG. 13, the customer holds the card over the precursor 12 and reads the card ID, sales serial number, change serial number, balance, and purchase designation area (A0).

  The refueling facility 11 obtains customer information corresponding to the card ID from the data center 2 or the POS 10 of its own store based on the data read by the preprocessing machine 12, and first, “sales numberer” and “fishing number” are one. It is determined whether or not it has been done (step S302).

If “sales sequence number” = “change sequence number” (step S302, Yes)), the change process has been completed as described above. Accordingly, the fueling facility 11 displays the following message based on the “customer previous purchase history” and the “favorite data” shown in FIG. 16 (step S303).
“I do n’t have any change.

The card balance is 4,500 yen. Please select from the three purchase menus.

1. Previous refueling condition: Regular gasoline 5,000 yen Preferred refueling condition: Regular gasoline 2,000 yen Refuel under different conditions. "
In response to such a message, one of the above menus is selected by the customer.

  The fueling facility 11 controls processing as follows in response to selection of any of the above three menus.

  First, if any of the menus “1. Last refueling condition: regular gasoline 5,000 yen” and “2. Preferred refueling condition: regular gasoline 2,000 yen” is selected, the specified amount and balance will be excessive or insufficient. Is calculated (step S304).

  If the balance is insufficient, an additional deposit or cancellation is prompted (step S304a). If the balance is not insufficient, the user is prompted to select whether or not to add money (step S304b). When “Cancel” is selected and input (S304a), the display of the processing step S303 is repeated.

  If there is no cancel selection input, “deposit / do not deposit” is selected and input (S304b). And it is determined whether there was any additional payment (step S305).

  If the determination is “no additional deposit” (No in step S305), the customer makes a payment by holding the non-contact precica and updates the refueling condition setting, the previous purchase history, and the sales serial number in the precica data (A1). ).

  If the instruction is “additional deposit” (step S305, Yes), the deposit amount is confirmed (step S306), and a confirmation message for the deposit amount and the balance is displayed (step S307). At that time, it is requested to hold the replica over the replica processor 12 again.

  As a result, the preprocessing machine 12 updates each of the setting of the refueling conditions, the previous purchase history, and the sales serial number, and writes them in the precursor (A1).

  On the other hand, in step S303, when the third menu, that is, “3. Refuel under different conditions” is selected, the refueling facility 11 gives the customer the choice of oil type (step S308), the refueling amount or the amount of money. Designate (step S309).

  Here, if there is an additional deposit (step S310, Yes), the deposit amount confirmation described above (step S306), the deposit amount and the balance are displayed (step S307), and the precica processor 12 Each of the setting, the previous purchase history, and the sales serial number is updated and written in the prefix (A1).

  Further, in the flow of FIG. 13, if “sales serial number” and “fishing serial number” do not match in the processing of the previous step S302 (No in step S302), the processing of FIG. 14 is continued.

  In the process of FIG. 14, since “sales serial number” and “change serial number” do not match, there is a change amount. Therefore, the fueling facility 11 displays a message “Checking the change amount” (step S311).

  During this message display period, the data center 2 or own store POS10 (see FIG. 4) is inquired about change amount information (step S312).

  When the change amount information is obtained in this way, processing similar to the processing after step S303 in FIG. 13 is performed.

  In the example shown in FIG. 14, since the process is performed when the “sales serial number” and the “change serial number” do not match, the change amount exists based on the change amount information obtained from the data center 2 or the own store POS 10. Yes. Accordingly, a message such as “There is a change amount of 500 yen” is displayed as the message in step S303.

  The rest of the processing is the same as that described above with reference to FIG.

  Further, in FIG. 13 (the same applies to FIG. 14), when the processing of A1 is completed, the processing flow of FIG. 15 is continued.

  That is, a refueling operation is performed according to the designated refueling conditions (step S313), and refueling is performed up to a designated refueling amount or a designated amount of money (step S314).

  Next, when refueling is completed, a receipt for refueling is output (step S315).

  At this time, if there is a change, the customer holds the change to the plica to the precica processor and receives the change (A2).

  Note that the data of the category “car wash” in the previous purchase history / favorite data stored in the purchase designation area of the non-contact prepaid card is used in the use of the card in a car wash machine (not shown).

  That is, a car wash machine (not shown) is connected to the POS 10 in the same manner as the fueling facility 11, and a non-contact precurer processor (not shown) is also installed near the car wash machine.

  Here, the specification of the car wash menu, the price clearing, the car wash, and the change process are performed in the same manner as in the fuel supply device 11.

That is, when car washing is performed corresponding to FIG. 13, corresponding to the processing step S303,
1. Previous car wash conditions: wax car wash, lower car wash 2. Preferred car wash conditions: coating car wash, lower car wash A switched display is performed such as washing the car under different conditions.

  In the above embodiment, the previous purchase history and favorite data are recorded and held in the designated area of the contactless prepaid card. The information of the purchase designated area is stored as a table corresponding to the identification ID for each card. It is also possible to provide the device or data center 2 so that it is read out and used whenever necessary.

  In such a case, the process B1 in FIG. 17 is the reading of the identification ID and the acquisition of the data from the POS device 10 or the data center 2. Further, the process B2 is a step of performing update control of the data center 2 by the POS device 10.
