  However, most of the coupons supplied by the conventional technology are premised on the one-time use as a so-called trial, and the effect of promoting the continuous use is weak. As a means for promoting such continuous use, a point service for each store is known. This point service refers to, for example, distributing stamp cards to customers and pressing the stamp according to the number of times the store is used or the amount of goods, etc. Or other special services. Such a point service is highly effective in promoting continuous use, but cannot be expected to attract new customers. Further, since the point card is distributed at each store, there is a problem that carrying around is troublesome. That is, at present, a simple service system that attracts new customers and promotes continuous use has not been developed yet.

  The present invention has been made against the background of the above circumstances, and its object is to provide a simple coupon service system that attracts new customers and promotes continuous use.

In order to achieve such an object, the gist of the present invention is that a central processing unit and a storage device, which are mainly connected to a predetermined communication line, should be paid as a price for goods or services. A coupon service system for supplying a coupon for discounting a predetermined amount from a predetermined amount as electronic information via the communication line, the server providing a discount rate or discount of the coupon as desired by a user A discount setting means that can set the amount within a predetermined discount change range and changes the discount change range that can be set in a coupon for each store according to the points accumulated for each store , and the coupon actual hand discount corresponding to the upper limit of the discount variation range that can be set on the coupon by the discount setting means upon use and by the use of the coupon Of converting the difference to the point of the discount, and point storage means for storing the points for each of the store corresponding to each user, the point of each of the stores that have been accumulated by that point storing means at a predetermined commission While converting mutually, the point for every shop is made to function as a point conversion means which can be converted into a common point with a predetermined rate.

In this way, the server can set the discount rate or discount amount of the coupon within a predetermined discount change range as desired by the user, and according to the points accumulated for each store. a discount setting means for changing the discount variation range that can be set for coupon per the store, a discount corresponding to the upper limit of the hands the discount variation range that can be set on the coupon by the discount setting means upon use of the coupon converting the difference between the actual discount by the use of the coupon to the point, and point storage means for storing the points for each of the store corresponding to each user, for each of the stores that have been accumulated by that point accumulating means Convert points to each other at a predetermined rate, and function as point conversion means that can convert points for each store into common points at a predetermined rate Since it is a can be performed as each other inseparable coupon services and point service, by giving priority to one of points to be discounted and accumulated by the coupons in response to the user's desire, for each store It is possible to meet the user's desires within the discount change range that can be set in the coupon, and to promote the continuous use of each store . Further, the accumulated points for each shop, that it allows conversion points for each the store to another store points to a common point, can promote continued use with gathering new customers for each store, Furthermore, there is an advantage that various services can be performed by a common point. That is, it is possible to provide a simple coupon service system that collects new customers and promotes continuous use.

Here , preferably, the discount setting means increases the upper limit of the discount change range that can be set in the coupon for each store as the points for each store are accumulated. In this way, there is an advantage that continuous use of the store can be further promoted.

  Preferably, the coupon is supplied to a mobile phone via the communication line and displayed on a display unit of the mobile phone. This has the advantage that the coupon can be used in a simple and practical manner.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a coupon service system 10 according to an embodiment of the present invention. The coupon service system 10 includes a relay base station 14 connected to a large number of mobile phones 12 via a predetermined wireless communication channel, and a communication server 16 connected to the relay base station 14. The communication server 16 is connected to the above-described many cellular phones 12, other wired telephones, communication terminals, computers, and the like via a gateway 18 and a communication line 20 such as a public telephone line. A coupon service provider server (central processing unit) 22 is one of them, so that information can be transmitted to and received from a large number of mobile telephones 12 via the communication server 16 and the communication line 20. It has become.

  The mobile phone 12 includes a control unit 24, a ROM 26, an operation unit 28 including buttons (switches) for inputting numbers, characters, symbols, and the like, and a display unit 30 capable of displaying characters, figures, symbols, images, and the like. , A storage unit 32 and, if necessary, a barcode reader 33 and the like. The control unit 24 is a so-called microcomputer that processes an input signal based on a program stored in the ROM 26 in advance, and controls the input of numbers or the like according to the input from the operation unit 28. Control is performed such that a call channel is established according to the telephone number input from the operation unit 28 so that mutual communication is possible, or communication is established according to the input URL so that information can be transmitted and received. . The storage unit 32 is a storage device such as a flash ROM capable of storing electronic information such as music information and image information. The barcode reader 33 is a reading device for reading a barcode representing store information and the like described in a coupon magazine or the like.

  The server 22 is a so-called computer configured to include a CPU 34, a ROM 36, a RAM 38, a display device 40 such as a CRT, and a storage device 42, and a program stored in the ROM 36 in advance using the temporary storage function of the RAM 38. Based on the input signal. The storage device 42 is provided with various databases such as a user-specific point database 44, a service rank table 46, and a point conversion rate database 48 described later.

  The coupon service system 10 is a coupon service that supplies, as electronic information, a coupon for discounting a predetermined amount from a predetermined amount (fixed amount) to be paid as a consideration for goods or services via the communication line 20; A point service for accumulating points for each user is provided when using a coupon (before and after the settlement using the coupon). The coupon is a so-called discount coupon in which a discount rate is set such as “two discounts for a fixed amount” or a discount amount is set such as “500 yen discount from a fixed amount”. In the coupon service of this embodiment, the discount rate or discount amount of such a coupon can be set on the user side within a predetermined discount change range. A mode for setting the rate will be described, and a mode for setting the discount amount will be omitted. In addition, the points are, for example, numerical values accumulated for each store in the user-specific point database 44, and can be exchanged for predetermined products, cash vouchers, or the like as pseudo-currencies, or when the accumulated points reach a predetermined numerical value. It is for providing services such as discounts. The points for each store are preferably converted into common points at a predetermined rate (yield). This common point is for exchanging tickets for large-scale events such as concerts that are difficult to provide at each store, or for special services that are common to a plurality of stores.

  FIG. 2 is a functional block diagram illustrating a coupon service control function performed by the CPU 34 of the server 22, and FIG. 3 is a diagram illustrating a coupon service process performed by the coupon service system 10. Hereinafter, the coupon service of the present embodiment will be described based on these drawings.

  First, in the process P1 shown in FIG. 3, the coupon magazine 66 etc. which introduces the contents of goods or services for each store and publishes the coupon number is referred to, and the coupon number desired by the user is selected. The coupon number is a store-specific number for specifying a desired store or an identification number for specifying the coupon itself. Next, in step P2, a coupon service site provided in the server 22 is accessed using the mobile phone 12 or the like as a communication terminal, and a coupon number desired by the user is transmitted from the mobile phone 12 to the server 22. Accepted.

  2 accepts a coupon number transmitted from the mobile phone 12 and stores it in the RAM 38 or the like. The coupon information display means 52 displays information corresponding to the coupon number received by the coupon number receiving means 50 based on the information stored in the user-specific point database 44. FIG. 4 is a diagram for explaining in detail an example of the information for each user stored in the user-specific point database 44. As shown in FIG. 4, the common points, the accumulation points for each store, the target points, Corresponding products and the like are stored. This target point indicates a product that can be exchanged for a predetermined point. For example, “2000” points for common points, JOYSOUND concert invitations, “1500” for sake shop “Nonbee” Depending on the common points accumulated at that time and points for each store, such as a special sake “Hokkaido Honor” at points, a restaurant “Horita” with “1000” points for a free lunch for one meal, etc. Determined. The coupon information display means 52 is, for example, the user's common points stored in the user-specific point database 44 and points for each store, target points and corresponding products and services, new arrival information, In addition, information such as each operation is displayed on the display unit 30 of the mobile phone 12.

  The discount change range display means 54 is based on the information stored in the user-specific point database 44 and the service rank table 46, and is discounted in advance corresponding to the coupon number accepted by the coupon number acceptance means 50. Display the range of change. FIG. 5 is a diagram for explaining in detail an example of the service rank table 46. As shown in FIG. 5, the range of accumulated points for each store, the discount rate change range corresponding to the range, the maximum discount rate, Is to be memorized. In addition, a rank for determining the color (white, copper, silver, gold) of the coupon corresponding to the range of accumulation points for each store is determined. For example, if the rank is “white”, that is, the accumulated points are in the range of “0-100”, the discount rate change range is one that allows selection of “0%, 5%, 7%, 10%”, the maximum discount rate Is "15%", and the rank change range is "0%, 5%, 10%, 13%" when the accumulation point is "101-500". The maximum discount rate is "16%", and the rank change rate is "0%, 5%, 10%, 15%" when the rank is "Silver", that is, the accumulation points are in the range of "501-1000" The maximum discount rate is “17%”, and the rank change range is “0%, 5%, 10” when the rank is “gold”, that is, the accumulation points are within the range of “1001”. The maximum discount rate is “18%”. In this way, the more the points for each store are accumulated, the higher the upper limit (maximum discount rate) of the discount rate change range that can be set for the coupon for each store, and the discount rate change range is It is determined in advance to be wide. The discount change range display means 54 refers to, for example, an accumulation point in a store corresponding to the coupon number accepted by the coupon number acceptance means 50, and as shown in FIG. 12, a discount rate corresponding to the accumulation point The change range is displayed in the discount change range display area 72 in the display unit 30 of the mobile phone 12.

  Next, in step P3 shown in FIG. 3, a coupon discount rate is set as desired by the user, and is supplied as electronic information from the server 22 to the mobile phone 12 via the communication line 20. The coupon as the electronic information is, for example, image information representing the coupon, a URL of a site for displaying the coupon, or the like, and is stored in the storage unit 32.

  The discount setting means 56 shown in FIG. 2 sets the coupon discount rate within the discount rate change range displayed by the discount change range display means 54 as desired by the user. The coupon supply means 58 supplies the coupon set with the discount rate by the discount setting means 56 to the mobile phone 12 via the communication line 20 as electronic information. The coupon supplied in this way can be confirmed by, for example, displaying the discount rate set by being displayed on the display unit 30 of the mobile phone 12, and as shown in FIG. The upper limit (maximum discount rate) of the discount rate change range can be visually confirmed by the color (white, copper, silver, gold).

  Next, in step P4 shown in FIG. 3, a coupon displayed on the display unit 30 of the mobile phone 12 is presented at the time of payment in the store, and a predetermined price to be paid as a consideration for goods or services in accordance with the coupon. A predetermined amount is discounted from the amount. In the settlement, for example, the discount rate of the presented coupon and the upper limit (maximum discount rate) of the discount change range represented by the color of the coupon are input to the register 68.

  Next, in process P5, the receipt 70 is punched out from the register 68 provided in the store. In this receipt 70, a point code representing points according to the actual discount rate set by the discount setting means 56 is described. The point code described in the receipt 70 is for determining points accumulated in the user-specific point database 44 by being received by the server 22, and is paid as a price for goods or services, for example. The predetermined amount (fixed amount) to be determined, the discount rate actually set for the coupon by the discount setting means 56, and the upper limit (maximum discount rate) of the discount rate change range that can be set for the coupon are encrypted. It has been

  Next, in steps P6 and P7, the mobile phone 12 or the like is used as a communication terminal to access a coupon service site provided in the server 22, and the point code described in the receipt 70 is transmitted from the mobile phone 12. Accepted by the server 22. The point code receiving means 60 shown in FIG. 2 receives the point code transmitted from the mobile phone 12 and stores it in the RAM 38 or the like. The point accumulating unit 62 accumulates points corresponding to the point codes received by the point code receiving unit 60 in the user-specific point database 44. Preferably, a discount amount corresponding to an upper limit (maximum discount rate) of the discount change range that can be set for the coupon by the discount setting means 56 and an actual discount amount corresponding to the discount rate set for the coupon. The difference is converted into points and accumulated. That is, as the discount rate set for the coupon by the discount setting means 56 is lower, more points are accumulated. Further, the point code receiving means 60 invalidates the reception of the point code that has been received once.

  The point conversion means 64 shown in FIG. 2 converts the points for each store stored in the user-specific point database 44 to each other or to a common point at the rate (rate) stored in the point conversion rate database 48. . FIG. 6 is a diagram for explaining in detail an example of the point conversion rate database 48. As shown in FIG. 6, the conversion rate of points for each store is stored with the common point as a reference, that is, “1”. For example, the point “1” of the sake shop “Nonbee” is converted into a common point “0.85”, and the point “1” of the restaurant “Horita” is converted into a common point “0.90”. This conversion rate is preferably set to a higher value for a popular store, that is, a store where a coupon service is frequently used by a user.

  FIG. 7 is a flowchart for explaining coupon service control by the CPU 34 of the server 22 and is repeatedly executed at a predetermined cycle.

  First, in step SA1 (hereinafter, step is omitted), the mobile phone 12 is connected to a coupon service site (MY coupon service) using the communication terminal as a communication terminal. Next, in SA2, an ID, password, etc., which are user identification information, are input. Next, in SA3, the coupon service screen as shown in FIG. 10 showing the coupons used so far, the accumulated points, the guidance of the service to be used, etc. is displayed on the display unit 30 of the mobile phone 12. Next, in SA4, it is determined whether the operation is a coupon use operation. If the determination at SA4 is negative, it is determined at SA8 whether or not it is a point conversion operation. If the determination at SA4 is positive, the coupon information display control SB shown in FIG. In step SA5 corresponding to the discount setting means 56, a discount rate desired by the user is selected from a plurality of discount rates displayed on the discount rate setting screen as shown in FIG. Is set as the actual discount rate. Next, in SA6 corresponding to the coupon supply means 58, a coupon with a discount rate set is supplied as electronic information to the mobile phone 12 via the communication line 20. The coupon is displayed on the display unit 30 of the mobile phone 12 as shown in FIG. Next, in SA7 corresponding to the point code accepting means 60, as shown in FIGS. 14 and 15, the receipt 70 which is stamped out from the register 68 at the time of settlement using the coupon supplied in SA6 is described in “ A point code such as “0251476274582” is input using the mobile phone 12 as a communication terminal and stored in the RAM 38 or the like. Then, after the point accumulation control SC shown in FIG. 9 is performed, this routine is terminated.

  If the determination in SA8 is negative, that is, if it is not a point conversion operation, the routine is terminated after other operations are performed in SA15, but if the determination in SA8 is positive, that is, If it is a point conversion operation, in SA9, the conversion source point type (common point or point for each store) is selected. Next, in SA10, the number of points to be converted is determined. Next, in SA11, the converted point type is determined. Next, at SA12, the point conversion rate stored in the point conversion rate database 48 is referred to and the number of converted points is calculated. That is, the product of the number of points determined in SA10 and a predetermined conversion rate is calculated. Next, in SA13, the number of points determined in SA10 is subtracted from the accumulated point type of the conversion source determined in SA9. In SA14, the number of points calculated in SA12 is added to the accumulated points of the converted point type determined in SA11, and then this routine is terminated. In the above control, SA9 to SA14 correspond to the point conversion means 64.

  In the coupon information display subroutine shown in FIG. 8, first, in SB1 corresponding to the coupon number receiving means 50, as shown in FIG. The mobile phone 12 is input as a communication terminal and stored in the RAM 38 or the like. When inputting a coupon number, a barcode described in the coupon magazine 66 or the like may be read by the barcode reader 33. Next, in SB2, information such as accumulated points and target points is read from the user-specific point database 44 for the store corresponding to the coupon number accepted in SB1. Next, in SB3, the service rank table 46 is referred to, and in SB4, a discount rate change range that can be selected in SA5 of FIG. 7 is determined. Then, at SB5, a discount rate setting screen as shown in FIG. 12 including the discount rate change range determined at SB4 is displayed, and then this routine is terminated. In the above control, SB2 to SB5 correspond to the coupon information display means 52 and the discount change range display means 54.

  In the point accumulation subroutine shown in FIG. 9, first, in SC1, the point code received in SA7 in FIG. 7 is decrypted and paid as a consideration for goods or services, and the coupon is actually applied in SA5 in FIG. And the discount rate set in (1) and the rank (maximum discount rate) of the coupon are read out. Next, in SC2, the difference between the discount amount corresponding to the maximum discount rate of the coupon read in SC1 and the actual discount amount corresponding to the discount rate set for the coupon is calculated. For example, when the accounting shown in the receipt 70 of FIG. 14 is performed, the fixed amount to be paid as the consideration for the goods or services is 4000 yen, the discount rate actually set for the coupon is 5%, and the maximum discount rate is The discount amount corresponding to the maximum discount rate is 18%, 720 yen at 18% of 4000 yen, and the discount amount corresponding to the actual discount rate is 200 yen at 5% of 4000 yen. Therefore, the difference between the discount amount corresponding to the maximum discount rate and the actually set discount amount is (720−200 =) 520 yen, and in the form of converting the difference of 10 yen into 1 point, the accumulated points are 52 points. Is done. Then, in SC4, after the points calculated in SC3 are accumulated as the corresponding store points in the user-specific point database 44, this routine is terminated. In the above control, SC1 to SC4 correspond to the point accumulation means 62.

  Thus, according to the present embodiment, the discount setting means 56 (SA5) that can set the discount rate or discount amount of the coupon within the predetermined discount change range according to the user's desire, and the coupon Since it includes point accumulation means 62 (SC1 to SC4) for accumulating points for each user according to the discount rate or discount amount set by the discount setting means 56 at the time of use, the coupon service and the point service are mutually connected. It can be performed as an inseparable thing, and it can respond to a user's desire within the said discount change range. That is, it is possible to provide a simple coupon service system 10 that collects new customers and promotes continuous use.

  The point accumulating unit 62 accumulates more points as the discount rate or discount amount set for the coupon by the discount rate setting unit 56 is lower. It is possible to give priority to either discounts or accumulated points, and there is an advantage that customer satisfaction can be improved. For example, in a drinking party by a group, it is possible to give a personal benefit to a user who is a secretary by giving priority to accumulated points. In addition, since it is difficult to determine whether or not to continue to use in the store for the first time, it is possible to save money by giving priority to discounts with coupons.

  The point accumulating means 62 converts the difference between the discount amount corresponding to the upper limit of the discount change range that can be set for the coupon by the discount setting means 56 and the actual discount amount due to the use of the coupon into points. Therefore, it is possible to give priority to either discounts or accumulated points by the coupon in a practical manner, and there is an advantage that customer satisfaction can be increased.

  Further, since the point accumulating means 62 accumulates points for each store, there is an advantage that new customers can be collected for each store and continuous use can be promoted.

  Moreover, since the point conversion means 64 (SA9 thru | or SA14) which mutually converts the point for every said store with a predetermined | prescribed commission is included, the satisfaction of a customer is raised by giving compatibility to the point for every said store. There is an advantage that

  Moreover, since the point conversion means 64 can convert the points for each store into a common point at a predetermined rate, by enabling the points for each store to be converted into common points with high versatility, There is an advantage that various services can be performed by the common point.

  Moreover, since the discount setting means 56 changes the discount change range that can be set in the coupon for each store according to the points accumulated for each store, it can further promote the continuous use of the store. There is an advantage.

  Moreover, since the discount setting means 56 increases the upper limit (maximum discount rate) of the discount change range that can be set in the coupon for each store as the points for each store are accumulated, There is an advantage that the continuous use of the store can be further promoted.

  Moreover, since the coupon is supplied to the mobile phone 12 via the communication line 20 and displayed on the display unit 30 of the mobile phone 12, the coupon can be used in a simple and practical manner. There is an advantage.

  The preferred embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to these embodiments, and may be implemented in other modes.

  For example, in the above-described embodiment, the coupon supply means 58 supplies a coupon, which is electronic information, to the mobile phone 12, and is displayed on the display unit 30 of the mobile phone 12 at the time of payment using the coupon. However, for example, the coupon supply unit 58 may supply a coupon, which is electronic information, to a general personal computer or the like. In this aspect, at the time of payment using the coupon, the printed coupon may be presented, or the URL of the site for displaying the coupon may be transmitted to be confirmed at the terminal on the store side.

  Further, in the above-described embodiment, in steps P4 to P6 shown in FIG. 3, the user presents a coupon displayed on the display unit 30 of the mobile phone 12, and the store side stores the coupon information in the register 68. For example, it is necessary to confirm the input and output by infrared communication between the mobile phone 12 and the register 68 or by sending and receiving mail. Input may be performed in a controlled manner. According to such a configuration, a coupon service system as simple as possible can be realized.

  Further, although not particularly mentioned in the above-described embodiment, it may be configured such that a service can be reserved by a store via the server 22. That is, a reservation service may be provided by the coupon service system 10. If it does in this way, there exists an advantage that it becomes unnecessary to show the coupon at the time of the adjustment which uses a coupon by supplying the information regarding the discount by a coupon, and the information regarding a reservation centrally. Furthermore, when a reservation cannot be made at a desired store, a service may be provided in which other stores that provide similar services are introduced instead.

  In the above-described embodiment, the discount setting means 56 is for selecting any one of a plurality of predetermined discount change rates such as “0%, 5%, 7%, 10%”. However, for example, a desired discount rate may be input as a numerical value within a range of “0% to 10%”. Also, the discount rate change range corresponding to the rank “white” is “0%, 5%, 7%, 10%” and the maximum discount rate is “15%”, which cannot be set as the maximum discount rate. However, this is intended to accumulate points, and it is natural that the maximum discount rate can be set as the actual discount rate.

  In the above-described embodiment, the points accumulated by the point accumulation means 62 are calculated on the server 22 side, but may be calculated by the register 68. In this embodiment, a point code representing the numerical value of the points stored by the point storage means 62 is input to the server 22.

  Moreover, although the above-mentioned Example demonstrated the aspect which selects a coupon number with reference to the said coupon magazine 66, what makes a coupon number select with reference to the coupon introduction site provided in the said server 22, etc., for example It may be. Moreover, you may make it the information regarding a coupon delivered by e-mail etc.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
