An embodiment described here generally relates to a points management method and a points management apparatus.
Conventionally, sharing (commonizing) by which the corporate currency (points) is usable between different issuers has been performed. For example, a common database or the like is provided between a plurality of issuers and the points issued by each points issuer are summed as common points in a common database, such that the points are shared. Alternatively, the database of each points issuer converts points managed on each database to other points, such that the points are shared.
By the way, managing points by using a distributed ledger of a blockchain or the like has been proposed. However, in the case of managing points by using the distributed ledger, a system of sharing the points does not exist.
In accordance with one embodiment, a points management method is for commonly managing points by using a distributed ledger, the points being issued to a customer in a manner that depends on purchase of a commodity or use of a service from a plurality of different points issue sources and being usable by the customer for at least a part of a price of purchase of a commodity or use of a service at a plurality of points use destinations. The points management method includes recording, in the distributed ledger, transaction data showing remaining points retained in a points account of each customer, the points account being used as a wallet. The points management method includes determining a points account of a customer by using an identification code uniquely given to each points account. The points management method includes determining remaining points retained in the determined points account on the basis of the transaction data. The points management method includes determining points of the determined remaining points on the basis of a function determined on the basis of a combination of one of the plurality of different points issue sources and one of the plurality of points use destinations, the points being usable at the one of the plurality of points use destinations.
A points system (reward system) according to an embodiment will be described with reference to the drawings. It should be noted that a configuration(s) will be omitted from some of the drawings, which will be referred to for describing the following embodiment, for the sake of description.

In ACT14, the processor 401 determines whether or not the points ID has been input. For example, when the reader/writer 406 or through the scanner 410 reads the points ID from the points card, the points ID output by the reader/writer 406 or the scanner 410 is input into the processor 401. In a case where the processor 401 determines that the points ID has not been input (No in ACT14), the processing of the processor 401 proceeds to ACT15.
In ACT15, the processor 401 determines whether or not the complete operation to complete registration of commodities has been performed. That is, the processor 401 determines whether or not a prescribed operation, for example, operating a subtotal button of the input device 409 has been performed. It should be noted that an operation of the processor 401 in a case where the complete operation has been performed in a state in which no commodities have been registered in the commodity list may be prescribed by a designer of a program of the processor 401. For example, the processor 401 ignores the complete operation. Alternatively, the processor 401 may be disabled to perform the complete operation itself in a state in which no commodities have been registered. In a case where the processor 401 determines that the complete operation has not been performed (No in ACT15), the processing of the processor 401 returns to ACT12. In this manner, the processor 401 repeats the processing of ACT12 to ACT15 until the processor 401 determines that the commodity code has been input (Yes in ACT12), determines that the biometric information has been read (Yes in ACT13), determines that the points ID has been input determines that (Yes in ACT14), or determines that the complete operation has been performed (Yes in ACT15).
The shopping client brings a commodity that the shopping client wishes to purchase to the POS terminal 400, for example. Then, the operator of the POS terminal 400 inputs the commodity code of the commodity into the POS terminal 400 by reading the barcode added to the commodity through the scanner 410, for example. In a case where the processor 401 determines in ACT12 that the commodity code has been input under the standby state of ACT12 to ACT15 (Yes in ACT12), the processing of the processor 401 proceeds to ACT16.
In ACT16, the processor 401 adds the commodity code input in ACT15 to the commodity list stored in the RAM 403, the auxiliary storage device 404, or the like. The processing of processor 401 returns to ACT12 after the processing of ACT16.
In a case where the processor 401 determines that the biometric information has been read under the standby state of ACT12 to ACT15, in ACT13, through the biometric sensor 407 (Yes in ACT13), the processing of the processor 401 proceeds to ACT17.
In ACT17, the processor 401 acquires a points ID by referring to a biometric information database in which pieces of biometric information are associated with points IDs on the basis of the biometric information read in ACT13. It should be noted that the biometric information database is stored in the auxiliary storage device 204 of the headquarter server 200, the auxiliary storage device 304 of the store server 300, the auxiliary storage device 404 of the POS terminal 400, a server common between the plurality of traders, the distributed ledger DL1, a P2P distributed storage, or the like, for example. The processor 401 acquires the biometric information database from any one of the above-mentioned locations and refers to the acquired biometric information database.
The processing of processor 401 proceeds to ACT18 after the processing of ACT17. Further, in a case where the processor 401 determines in ACT12 that the points ID has been input under the standby state of ACT12 to ACT15 (Yes in ACT14), the processing of the processor 401 proceeds to ACT18.
In ACT18, the processor 401 stores the points ID acquired in ACT17 or the points ID input in ACT14. That is, the processor 401 substitutes the points ID acquired in ACT17 or the points ID input in ACT14 for the variable VP1. It should be noted that the points ID stored as the variable VP1 will be referred to as a “target points ID” hereinafter.
In ACT19, the processor 401 acquires, from the distributed ledger DL1, the remaining points retained in the points account (hereinafter, referred to as a “target points account”) determined on the basis of the target points ID in the following manner, for example. The processor 401 acquires a transaction (transaction information) recorded in the distributed ledger DL1. Then, the processor 401 extracts only a transaction history, which is associated with the target points account, from transaction histories of the points recorded in the transaction. In addition, the processor 401 determines the remaining points of the target points account from the extracted transaction history by calculation. In this manner, the processor 401 acquires the remaining points. It should be noted that the target points account retains points issued by each issue source. The processor 401 determines the remaining points of the target points account for each points issue source. For example, the processor 401 determines the remaining points for each issue source. For example, the processor 401 determines the remaining points whose issue source is the trader S1 as P1 [points], the remaining points whose issue source is the trader S2 as P2 [points], the remaining points whose issue source is the trader S3 as P3 [points], and so on. As described above, the transaction is an example of the transaction data showing remaining points. Therefore, the processor 401 functions as an acquisition unit that acquires the transaction data showing remaining points by acquiring the transaction.
In ACT20, the processor 401 determines the usable points. It should be noted that in a case of using the points in the points system 1, points corresponding to a value calculated in accordance with a certain calculation expression determined on the basis of the points issue source and the points use destination are usable. For example, it is assumed that in a case of using points of Pa [points] issued by a trader Sa in a trader Sb, points of Pb [points] are usable. At this time, Pb can be determined on the basis of a function f(Pa) of Pa. The function f is as in Expression (1) below, for example. It should be noted that Pb [points] will be sometimes referred to as “usable points”.
Pb=f(Pa)=α*Pa−β (1)
Where α is a coefficient determined on the basis of a combination of the points issue source and the points use destination. Further, β is a number determined on the basis of the combination of the points issue source and the points use destination. It should be noted that β is typically 0. The function f is defined by a table T1 as shown in
In ACT21, the processor 401 informs the operator of the POS terminal 400 and the shopping client of the usable points determined in ACT20. For example, the processor 401 causes the display device 408 to display an image IM1 as shown in
In a case where the processor 401 determines in ACT15 that the complete operation has been performed under the standby state of ACT12 to ACT15 (Yes in ACT15), the processing of the processor 401 proceeds to ACT22. In ACT22, the processor 401 determines whether or not points to be used in settlement (hereinafter, referred to as “use points”) has been input by the input device 409, for example. It should be noted that the use points need to be equal to or smaller than maximum points and equal to or smaller than a total amount of commodities and services registered in the commodity list. It should be noted that a total amount includes a tax, a service charge, and the like. In a case where the processor 401 determines that the use points have not been input (No in ACT22), the processing of the processor 401 proceeds to ACT23.
In ACT23, the processor 401 determines whether or not to start settlement processing. The processor 401 determines to start the settlement processing in response to operation on the button of the input device 409 for instructing to start the settlement processing, for example.
In a case where the processor 401 determines not to start the settlement processing (No in ACT23), the processing of the processor 401 returns to ACT22. In this manner, the processor 401 repeats the processing of ACT22 and ACT23 until the processor 401 determines that the use points have been input (Yes in ACT22) or determines to start the settlement processing (Yes in ACT23).
In a case where the processor 401 determines in ACT22 that the use points have been input under the standby state of ACT22 and ACT23 (Yes in ACT22), the processing of the processor 401 proceeds to ACT24.
In ACT24, the processor 401 calculates the remaining amount obtained by subtracting the use points from the total amount. Then, the processor 401 informs of the remaining amount. For example, the processor 401 causes the display device 408 to display the remaining amount. The processing of processor 401 proceeds to ACT23 after the processing of ACT24.
In a case where the processor 401 determines in ACT23 to start the settlement processing under the standby state of ACT22 and ACT23 (Yes in ACT23), the processing of the processor 401 proceeds to ACT25. In ACT25, the processor 401 performs the settlement processing. It should be noted that regarding settlement by payment other than points of the cash, the credit card, and the like, the description will be omitted because a well-known method can be used. Here, only the settlement using the points will be described with reference to
In ACT31 of
In ACT32, the processor 401 substitutes 0 for the variable j. The variable j is a counter.
In ACT33, the processor 401 determines whether or not the value of the variable q1 exceeds 0. In a case where the processor 401 determines that the value of the variable q1 exceeds 0 (Yes in ACT33), the processing of the processor 401 proceeds to ACT34. In ACT34, the processor 401 substitutes 1 for a variable i. The variable i is a counter.
In ACT35, the processor 401 determines whether or not the value of the variable q1 is equal to or smaller than the value p3_i. It is assumed that the usable points whose issue source are the trader S1 is p3_1 and the usable points whose issue source is the trader S2 are p3_2, . . . Generalizing them, a value p3_k indicates usable points whose issue source is a trader Sk. It should be noted that k is an integer which is equal to or larger than 1 and equal to or smaller than k_max. Where k_max is a total number of issue sources. In a case where the processor 401 determines that the value of the variable q1 is equal to or smaller than the value p3_i (Yes in ACT35), the processing of the processor 401 proceeds to ACT36.
In ACT36, the processor 401 substitutes the value of the variable q1 for a variable q2_i. It should be noted that the variable q2_i indicates points to be used in a case where the issue source uses points of a trader Si. In ACT37, the processor 401 substitutes a calculation result of f_i(q1) for a variable q3_i. It should be noted that f_i is a function f about the points whose issue source is the trader Si. For example, f_i(q1)=(α_i*q1−β_i) is established. It should be noted that α_i is a value of a about the points whose issue source is the trader Si. Further, β_i is a value of β about the points whose issue source is the trader Si. It should be noted that the variable q3_i indicates usable points in a case of using q2_i [points] of the points whose issue source is the trader Si.
On the other hand, in a case where the processor 401 determines that the value of the variable q1 exceeds the value p3_i (No in ACT35), the processing of the processor 401 proceeds to ACT38. In ACT38, the processor 401 substitutes a value p2_i for the variable q2_i. It is assumed that remaining points whose issue source is the trader S1 are p2_1 and the remaining points whose issue source is the trader S2 are p2_2, . . .
Generalizing them, remaining points whose issue source is the trader Sk is p2_k. In ACT39, the processor 401 substitutes the value p3_i for the variable q3_i.
The processing of processor 401 proceeds to ACT40 after the processing of ACT37 or ACT39. In ACT40, the processor 401 substitutes a calculation result of (q3_i/q2_i) for a variable q4_i. It should be noted that the variable q4_i indicates what times of q2_i [points] usable points in a case of using q2_i [points] of the points whose issue source is the trader Si are. In ACT41, the processor 401 increments the value of the variable i by 1.
In ACT42, the processor 401 determines whether or not the value of the variable i is equal to or smaller than the value k_max. In a case where the processor 401 determines that the value of the variable i is equal to or smaller than the value k_max (Yes in ACT42), the processing of the processor 401 returns to ACT35. On the other hand, in a case where the processor 401 determines that the value of the variable i exceeds a value k_max (No in ACT42), the processing of the processor 401 proceeds to ACT43 of
In ACT43, the processor 401 substitutes 1 for the variable i. In ACT44, the processor 401 substitutes 0 for a variable q4_max.
In ACT45, the processor 401 determines whether or not the value of the variable q4_max is smaller than the value of the variable q4_i. In a case where the processor 401 determines that the value of the variable q4_max is smaller than the value of the variable q4_i (Yes in ACT45), the processing of the processor 401 proceeds to ACT46. In ACT46, the processor 401 substitutes the value of the variable q4_i for the variable q4_max. In ACT47, the processor 401 substitutes the value of the variable i for a variable i_max.
On the other hand, in a case where the processor 401 determines that the value of the variable q4_max is equal to or larger than the value of the variable q4_i (No in ACT45), the processing of the processor 401 proceeds to ACT48. Further, the processing of the processor 401 proceeds to ACT48 also after the processing of ACT47.
In ACT48, the processor 401 increments the value of the variable i by 1. In ACT49, the processor 401 determines whether or not the value of the variable i is equal to or smaller than the value k_max. In a case where the processor 401 determines that the value of the variable i is equal to or smaller than the value k_max (Yes in ACT49), the processing of the processor 401 returns to ACT45. On the other hand, in a case where the processor 401 determines that the value of the variable i exceeds the value k_max (No in ACT49), the processing of the processor 401 proceeds to ACT50. The processor 401 repeats the processing of ACT45 to ACT49 as described above, to thereby determine an issue source from which the points should be used for minimizing the points to be used. In a case where the processor 401 determines that the value of the variable i exceeds the value k_max (No in ACT49), the value of the variable q4_max is a maximum value of q4_i in a range of 1≤i≤k_max. Further, in a case where the processor 401 determines that the value of the variable i exceeds the value k_max (No in ACT49), the variable i_max indicates that the points to be used are minimum in a case of using points whose issue source is the trader Si_max.
In ACT50, the processor 401 increments the value of the variable j by 1. In ACT51, the processor 401 substitutes a calculation result of (q1−q3_(i_max)) for the variable q1. In ACT52, the processor 401 substitutes a value of the variable i_max for a variable r1_j. It should be noted that the variable r1_j indicates an issue source from which the points should be used. In ACT53, the processor 401 substitutes a value of the variable q2_(i_max) for a variable r2_j. It should be noted that the variable r2_j indicates that the issue source uses r2_j [points] of points of a trader Sr1_j. The processor 401 returns to ACT33 of
In a case where the processor 401 determines that the value of the variable q1 is equal to or smaller than 0 (No in ACT33), the processing of the processor 401 proceeds to ACT54. In ACT54, the processor 401 performs processing for using r2_1 [points] of the points whose issue source is the trader Sr1_1, r2_2 [points] of the points whose issue source is the trader Sr1_2, . . . , and r2_j [points] of the points whose issue source is the trader Sr1_j from the target points account. For example, the processor 401 posts each of a transaction in which the points whose issue source is a trader Sr1_1 are subtracted by r2_1 [points] from the target points account, a transaction in which the points whose issue source is a trader Sr1_2 by r2_2 [points] from the target points account, . . . , and a transaction in which points whose issue source is a trader Sr1_j-1 is subtracted by r2_j [points] from the target points account, to the distributed ledger DL1. Correspondingly, the distributed ledger DL1 agrees with and authorizes the posted transactions. Accordingly, those transactions are recorded in the distributed ledger DL1. It should be noted that post of the transaction may be directly performed by the POS terminals 400 or may be performed by the headquarter server 200 or the store server 300 on the basis of the information sent from the POS terminal 400. The processor 401 terminates the processing shown in
The description will be continued referring back to
In ACT27, the processor 401 gives points corresponding to a purchase amount to the target points account. For example, the processor 401 gives the points of Pc=γ×(total amount−use points) [points].
It should be noted that γ is a value equal to or smaller than 1, which varies depending on the issue source. For example, in a case where the POS terminal 400 is installed by the trader Sk, the processor 401 posts a transaction for incrementing the points whose issue source is the trader Sk by Pc [points] to the target points account in the distributed ledger DL1. It should be noted that post of the transaction may be directly performed by the POS terminal 400 as described above or may be the headquarter server 200 or the store server 300 on the basis of the information sent from the POS terminal 400.
The processing of processor 401 proceeds to ACT28 after the processing of ACT27. Further, in a case where the processor 401 determines that the points ID is not stored as the variable VP1 (No in ACT26), the processing of the processor 401 proceeds to ACT28. In ACT28, the processor 401 sends information regarding the transaction in which the settlement has been performed to the headquarter server 200 or the store server 300. Correspondingly, the headquarter server 200 or the store server 300 records the sent information regarding the transaction. It should be noted that in a case where it is the POS terminal 400 installed by the trader in which the store server 300 and the headquarter server 200 is not installed as in the trader S3, the processor 401 does not perform the processing of ACT28.
Next, processing of the client terminal 500 will be described with reference to
In ACT61 of
In ACT62, the processor 501 determines whether or not the biometric information has been read through the biometric sensor 507. In a case where the processor 501 determines that the biometric information has not been read by the biometric sensor 507 (No in ACT62), the processing of the processor 501 proceeds to ACT63.
In ACT63, the processor 501 determines whether or not the points ID has been input. For example, when the reader/writer 506 or the scanner 509 reads the points ID from the points card, the points ID output by the reader/writer 506 or the scanner 509 is input into the processor 501. In a case where the processor 501 determines that the points ID has not been input (No in ACT63), the processing of the processor 501 returns to ACT62. In this manner, the processing of the processor 501 repeats ACT62 and ACT63 until the processor 501 determines that the biometric information has been read through the biometric sensor 507 (Yes in ACT62) or the processor 501 determines that the points ID has been input (Yes in ACT63).
In a case where the processor 501 determines in ACT62 that the biometric information has been read through the biometric sensor 507 under the standby state of ACT62 and ACT63 (Yes in ACT62), the processing of the processor 501 proceeds to ACT64.
In ACT64, the processor 501 acquires a points ID by referring to a biometric information database in which pieces of biometric information are associated with points IDs on the basis of the biometric information read in ACT62. It should be noted that the biometric information database is stored in the auxiliary storage device 204 of the headquarter server 200, the auxiliary storage device 304 of the store server 300, the auxiliary storage device 404 of the POS terminal 400, the client terminal 500, or a server common between the plurality of traders, the distributed ledger DL1, a P2P distributed storage, or the like, for example. The processor 501 acquires the biometric information database from any one of the above-mentioned locations and refers to the acquired biometric information database.
In a case where the processor 501 determines in ACT63 that the points ID has been input under the standby state of ACT62 and ACT63 (Yes in ACT63), the processing of the processor 501 proceeds to ACT65. In ACT65, the processor 501 stores the points ID acquired in ACT64 or the points ID input in ACT63. That is, the processor 501 substitutes the points ID acquired in ACT64 or the points ID input in ACT63 for the variable VP2. It should be noted that the points ID stored as the variable VP2 will be referred to as a “target points ID” hereinafter.
In ACT66, the processor 501 stands by until the points use destination is input. The operator of the client terminal 500 selects one of the trader S1 to the trader Sk_max as the points use destination and inputs the selected one, for example. In a case where the processor 501 determines that the points use destination has been input (Yes in ACT66), the processing of the processor 501 proceeds to ACT67.
In ACT67, the processor 501 acquires the remaining points of the target points account. It should be noted that the processor 501 acquires the remaining points as in ACT19, for example. In ACT68, the processor 501 determines the usable points as in ACT20.
In ACT69, the processor 501 informs the operator of the client terminal 500 of the usable points determined in ACT68. For example, the processor 501 causes the touch panel 508 to display the image IM1 as shown in
The points system 1 according to the embodiment manages points by using the distributed ledger DL1. Therefore, the cost for points management can be made lower than that according to the conventional method without the distributed ledger. Further, the points system 1 according to the embodiment has higher security and fault-tolerance than those in the case of not using the distributed ledger.
With the points system 1 according to the embodiment, the POS terminal 400 determines usable points on the basis of the function f (see
Further, with the points system 1 according to the embodiment, the POS terminals 400 displays the remaining points, the usable points, and the function f of each issue source with respect to the target points account on the display device 408 (see
With the points system 1 according to the embodiment, the POS terminal 400 determines usable points on the basis of the coefficient α (see
The following modification of the above-mentioned embodiment may be made. The headquarter server 200 or the store server 300 may perform some of the processes performed by the POS terminal 400 in the above-mentioned embodiment. In this case, the POS terminal 400, the headquarter server 200, and the store server 300 operate as the points management apparatus in cooperation. Alternatively, the headquarter server 200 or the store server 300 operates as the points management apparatus. The headquarter server 200 or the store server 300 may perform some of the processes performed by the client terminal 500 in the above-mentioned embodiment. In this case, the client terminal 500 and the headquarter server 200 or the client terminal 500 and the store server 300 operate as the points management apparatus in cooperation. Alternatively, the headquarter server 200 or the store server 300 operates as the points management apparatus.
In the above-mentioned embodiment, the points issue source is each trader. However, the points issue source may be each store. Alternatively, the plurality of traders or stores may be a common issue source.
In the above-mentioned embodiment, the POS terminal 400 automatically determines an issue source from which the points should be used in a manner that depends on the use points. However, the POS terminal 400 may be capable of separately inputting an issue source from which the points are to be used and how much points are to be used. In this case, the POS terminal 400 performs settlement using points in a manner that depends on that input.
In the above-mentioned embodiment, the trader having the actual store has been shown as an example. However, the trader may be a trader which has no stores and sells commodities or services by mail, for example. In this case, in the above-mentioned embodiment, the processing performed by the POS terminal 400 performs the headquarter server 200 or the like, for example.
The points managed by the points system 1 may be points that can be purchased using the legal tender or the like. That is, the points managed by the points system 1 may be prepaid-type electronic money. In addition, the points system 1 is capable of managing various other points. Further, the points managed by the points system 1 are not limited to the corporate currency and may be local money or the like.
The headquarter server 200 also serves as the node 100. The store server 300 also serves as the node 100.
The remaining points may be recorded in a state database (DB) or the like as shown in Hyperledger fabric. The state DB records a transaction or the like of the latest state after the transaction is executed. In this case, the POS terminal 400 may acquire the remaining points from the state DB. Each of the headquarter server 200, the store server 300, the POS terminal 400, the client terminal 500, and the like does not need to calculate the remaining points on the basis of the transaction by acquiring the remaining points from the state DB. Accordingly, each of the above-mentioned apparatuses can perform the processing in a shorter time. It should be noted that the processor 401 functions as an acquisition unit that acquires the transaction data showing remaining points by acquiring the remaining points from the state DB.
The processor 101, the processor 201, the processor 301, the processor 401, or the processor 501 may realize some or all of the processes to be realized by the program in accordance with the hardware configuration of the circuit in the above-mentioned embodiment.
