Description

BACKGROUND OF THE INVENTION
• 1. Field of the Invention[0001]
• The present invention relates to a portable electronic device that is held by customer and to store individual information and more particularly to a portable electronic device that is capable of providing a service to add loyalty point according to a degree of utilization of a store by customer and a loyalty point system in the retail business.[0002]
• 2. Description of the Related Art[0003]
• A special benefit system called as a loyalty point system has been introduced into retail stores including supermarkets in recent years. This system converts a total amount of money of purchased merchandises into loyalty points every time when a customer purchased merchandises and the loyalty points are accumulated. When the accumulated loyalty points reach a prescribed value, a little gift or a coupon is presented/merchandises purchased next time are discounted aiming at the fixation of customers.[0004]
• This system generally uses card type media including magnetic cards and the like. In other words, a customer who is a member of this system and carrying a membership card issued from a store shows the membership card to a store clerk when purchases merchandises and pays a price. The shop clerk registers the sales data of the merchandise purchased by that customer in such a merchandise sales data processor as an electronic cash register, a POS terminal, etc. At the same time, the card data of the membership card is read by a card reader/writer provided to the merchandise sales data processor. An accumulated loyalty point up to the last time is recorded on this membership card.[0005]
• After reading accumulated loyalty point data of a membership card by the card reader/writer, the merchandise sales data processor obtains the total amount of money for merchandise purchased by a customer by processing the registered merchandise sales data and converts the total amount of money into a loyalty point. Then, the loyalty point calculated this time is added to the accumulated loyalty point data read from the membership card and this added value is written into the membership card as an accumulated loyalty point up to the present time by the card reader/writer. This loyalty point system has been programmed as described above.[0006]
• In Japanese Laid-Open Patent Publication No. Hei 9-212743 and Japanese Laid-Open Patent Publication No. Hei 6-76124, the application of this system to provide the special service, wherein loyalty points are calculated by changing the point conversion ratio according to the amount of money and by setting the loyalty point conversion at a higher level than the ordinary level, was disclosed.[0007]
• In the existing system described above, point information is read out of a card that recorded loyalty points and after calculating loyalty point by a card processor that is generally called as a reader/writer, the calculated loyalty point information is recorded on a card. However, there was a possibility of illegally calculating loyalty points by maliciously rewriting a program stored in a card processor by a store clerk. Further, for calculating loyalty points it is necessary to output individual information recorded on a card to an external device (a card processor), there is generated a problem from, the viewpoint of security.[0008]

• FIG. 4 is a diagram showing a table T[0029]1 relative to individual information that is stored in thedata memory22 of theIC card7. As shown in FIG. 4, such individual information as, for example, name “HANAKO TOSHIBA”22a,date of birth “1970-3-3”22b,management number “98765”22c,phone number “03-1234-5678”22d,number of times of coming to store “3 times”22e,purchase amount of money “12345 Yen”22f,number of loyalty points “500 points”22g,adding date of loyalty point “2000-1-1” 22h,and term of validity “2000-3-31” 22I are stored in thedata memory 22.
• Of these individual information, information relative to[0030]name22a,date ofbirth22bandmanagement number22cis a fixed information. Information relative tophone number22d,number of times of coming to thestore22e,purchase amount ofmoney22f,number ofloyalty point22g,adding data ofloyalty point22hand term of validity22I are variable information. In particular, of these variable information, number of times of coming to thestore22e,purchase amount ofmoney22f,number of loyalty points22gand adding date ofloyalty point22hare information to be updated whenever a customer who has theIC card7 purchases merchandises.
• FIG. 5 is a diagram showing a table T[0031]2 of the loyalty point service information related to the loyalty point service application stored in thedata memory22 of theIC card7. As shown in FIG. 5, “Item”, “Qualification”, “Ratio of Service” for the service to be added especially in connection with the individual information are to be stored/set on the table T2 of the loyalty point service.
• As the “Item” to be added to the service especially in connection with the individual information, for example, “Number of Basic Loyalty points”[0032]30, “Number of Visiting Store”31, “Date of Birth”32, “Purchase Amount of Money”33 and “Phone Number”34 are stored/set. Corresponding to “Number of Basic Loyalty Points”30, “Every 100 Yen”30aand “5 Loyalty point”30bare stored as “Qualification” and “Service Ratio”, respectively. So, it is so set that 5 loyalty points are added to the number of basic loyalty points for the purchase of every 100 yen.
• Further, corresponding to “Number of Visting Store”, plural figures are set for “Qualification” and “Service Ratio” so that a different “Service Ratio” is set for each qualification step. That is, as “Qualification”, “Above 5”, “Above 10” and “Above 20”[0033]31aare set by stages. As “Service Ratio”, “2 multiple”, “3 multiple” and “5 mulitple”31bare set by stages. As a result, when the number of visiting store is above 5, the calculated number of loyalty points is doubled and when above 10, the number of loyalty points is trebled and when above 20, it is increased by 5 multiple.
• Further, corresponding to the date of[0034]birth32, “Agreed with Date”32ais stored as “Qualification” and “3 multile” is stored as “Service Ratio”. As a result, it is so set that when “Date of Birth” agreed with the date information, the number of calculated loyalty points is further trebled.
• Further, corresponding to “Purchase Amount of Money”[0035]33, plural figures are set for “Qualification” and “Service Ratio” so that “Service Ratio” becomes different according to the qualification step. That is, “Above 50,000 yen”, “Above 80,000 yen” and “Above 100,000 yen”33aare set by stages as “Qualification”. “2 multiple”, “3 multiple” and “5 multiple”33bare stored by stages as “Service Ratio”. As a result, it is so set that when the purchase amount of money is above 50,000 yen, the calculated number of loyalty points is further doubled, when above 80,000 yen, it is trebled and when above 100,000 yen, it is further increased by 5 multiple.
• Further, corresponding to “Phone Number”, “[0036]Lower 2 digits agrees with 01”34ais stored as “Qualification” and “3 multiple”34bis stored as “Service Ratio”. It is so set that as a result, when the lower 2 digits of a phone number agreed with “01”,the calculated number of loyalty points is further trebled.
• FIG. 6 is a flowchart for explaining the loyalty point adding process executed by the reader/[0037]writer8 and theIC card7 when a customer who has theIC card7 purchased merchandises according to the loyalty point system using theIC card7 set as described above. As shown in FIG. 6, first when the IC card is inserted into theIC card slot8cof the reader/writer8 (ST10), various purchase information, for example, purchase amount of money and the like are input by a store clerk from the keyboard (ST11). When the purchase information is input in the step ST11, the reader/writer8 outputs the purchase information and also, the date information to the IC card7 (ST12) and is put in the standby state (ST13).
• When the purchase information and date information are input from the reader/[0038]writer8 to theIC card7 via the contact portion25 (ST14 and ST15), theCPU21 executes the loyalty point calculation process described later (ST16). When the loyalty points are calculated in Step ST16, theCPU21 updates theindividual information22e-22hstored in thedata memory22. That is, theCPU21 stores a new figure of “Number of visiting store”22ewith “+1” added in the table T1 of thedata memory22. Further,CPU21 stores a new purchase amount of money added with the purchase amount of money of this time in the table T1. Further, theCPU21 stores a new number of loyalty point added a number of loyalty point calculated this time to “Number of loyalty points”22gin the Table T1 and stores the data information of this time for “Adding date of loyalty point”22hin the Table T1 (ST17). In addition, theCPU21 outputs the loyalty point information calculated in Step ST16 to the reader/writer8 (ST18).
• When loyalty point information that is output from the[0039]IC card7 is input (ST19), the reader/writer8 displays that information on thedisplay8afor visual check by a customer who has an IC card (ST20), ejects the IC card for returning to that customer (ST21) and terminates the loyalty point adding process.
• FIG. 7 is a flowchart for explaining the loyalty point calculation process of the IC card in Step ST[0040]16 shown in FIG. 6. As shown in FIG. 7, theCPU21 of theIC card7 first calculates a new purchase amount of money by adding the purchase amount of money information of this time included in the purchase information input in Step ST14 to “Purchase Amount of Money”22fon the table T1 of thedata memory22. Then, based on “Qualification” of “Number of Basic Loyalty Points” 30; that is, “Every 100 Yen” and “Service Ratio”; that is, “5 point” on the Table T2 of thedata memory22, theCPU21 calculates the number of basic loyalty point A corresponding to a new money information (ST30).
• Next, the[0041]CPU21 compares a new number of visiting store, which is “+1” added to the number of times read from “Number of Visiting Store”22eon the table T1 of thedata memory22, with the number of times that is set for “Qualification” (Above 5 times, 10 times and 20 times)31aof “Number of Visiting Store” (ST31) on the table T2 of thedata memory22. As a result of the comparison in Step ST31, when the new number of visiting store is in excess of 5, 10 or 20, special loyalty points corresponding to the number of visiting store are added. That is, numbers of loyalty point B that is the number of basic loyalty points calculated in Step ST30 multiplied by “Service Ratio” (2, 3 or 5 multiple)31bcorresponding to the Table T2 is calculated (ST32). As a result of the comparison in Step ST31, when a new number of times of visiting store is less than 5, a special loyalty point according to the number of visiting store is not added (that is, B=A) (ST33).
• Next, the[0042]CPU21 compares the date read from “Date of Birth”22bof the Table T1 with the date information input in Step ST15 (ST34). As a result of the comparison in Step ST34, when the date of birth agreed with the data of this time, the special loyalty point in connection with the date of birth is added. That is, the number of loyalty points C is calculated by multiplying the number of loyalty points B calculated in Step ST32 or ST33 by “Service Ratio” (3 multiple) corresponding to “Date of Birth”32 on the table T2 (ST35). As a result of the comparison in Step ST34, when the date of birth does not agree with the date of this time, a special loyalty point in connection with the date of birth is not added (that is, C=B) (ST36).
• Then, the[0043]CPU21 compares the selling amount of this time that is included in purchase information input in Step ST14 with the amount of money set for the qualification (above 50,000 yen, 80,000 yen and 10,000 yen)33aof “Purchase Amount of Money”33 on the table T2 (ST37). As a result of the comparison in Step ST37, when the purchase amount of money of this time is in excess of 50,000 yen or 80,000 yen or 100,000 yen, a special loyalty point in connection with the purchase amount of money is added. That is, the number of loyalty points D is calculated (ST38) by multiplying the number of loyalty points C that is calculated in Step ST35 or ST36 by “Service Ratio” (2, 3 or 5 multiple)33bcorresponding to “Purchase Amount of Money”33 on the tale T2. As a result of the comparison in Step ST37, when the purchase amount of money of this time is below 50,000 yen, a special loyalty point in connection with the purchase amount of money is not added (that is, D=C) (ST39).
• Then, the[0044]CPU21 compares the lower two digit values of a phone number read from “Phone Number”22don the table T1 with a value “01” set for “Qualification” (the lower two digits are 01) of “Phone Number”34 on the table T2 (ST40). As a result of the comparison in Step ST40, when the lower two digits are “01”, a special loyalty point in connection with the phone number is added. That is, the number of loyalty points E is calculated (ST41) by multiplying the number of loyalty points D calculated in Step ST38 or ST39 by “Service Ratio” (3 multiple)34bcorresponding to “Phone Number” on the table T2. As a result of the comparison in Step ST40, when the lower 2 digits are not “01”, a special loyalty point in connection with the phone number is not added (that is, E=D) (ST42). Thus, the number of loyalty points E calculated in Step ST41 or ST42 is decided as the number of loyalty points at this time and the loyalty point calculation process is terminated (ST43).
• FIG. 8 is a flowchart for explaining the installation of a loyalty point service application in the[0045]IC card7 that expired the data of validity in the loyalty point system A using theIC card7 set as described above. That is, in this embodiment, when the term of validity of theIC card7 expired, after the cashing process of loyalty points, the application in the IC card is changed to another higher loyalty point service application. Further, those portions for the same process as shown in FIG. 6 are assigned with the same step numbers.
• As shown in FIG. 8, when the IC card is first inserted into the[0046]IC card slot8cof the reader/writer8 (ST10), various kinds of purchase information including purchase amount of money information are input by a store clerk through thekeyboard8b(ST11). When the purchase information is input in ST11, the reader/writer8 outputs the purchase information to the IC card7 (ST12) and also, outputs the date information and is placed in the standby state (ST13).
• When purchase information and date information are input to the[0047]IC card7 from the reader/writer via the contact portion25 (ST14 and ST15), theCPU21 reads “Term of Validity”22iout of the table T1 of thedata memory22 and compares it with date information input in Step ST15 (ST50). As a result of the comparison in Step ST50, when the date is judged to be within the term of validity, the work proceeds to the loyalty point calculation process inStep16. Further, when the date is judged to be within the term of validity, the process contents after Step ST16 are the same as the processes after Step ST16 shown in FIG. 6. Further, when it is judged the term of validity expired as a result of the comparison in Step ST50, theCPU21 reads “Number of Loyalty Points”22gout of the table T1 and outputs information on the expiration of the term of validity to the reader/writer9 together with this “Number of Loyalty Points” as cashing information of loyalty point (ST51).
• When information on cashing loyalty point and information on the term of validity expiration output from the[0048]IC card7 are input to the reader/writer8, the reader/writer8 executes a prescribed cashing process for information on the cashing loyalty point and returns the service for the cashing loyalty point to a customer holding the IC card7 (ST53). Further, the reader/writer8 outputs a loyalty point service application for changing with the improved services including loyalty point ratio, etc. based on the input information on the expiration of term of validity (ST54).
• When the loyalty point service application for changing is input to the[0049]IC card7 from the reader/writer8, theCPU21 updates the loyalty point service application in the data memory22 (ST55). When the updating of the application in Step ST55 is completed, theCPU21 proceeds to Step ST56 and executes the loyalty point calculation process for the purchase of this time (ST56). When the loyalty point is calculated in Step ST56, theCPU21 updates theindividual information22e-22hstored in thedata memory22. That is, theCPU21 stores a new number of times with “+1” added to “Number of Visiting Store”22ein the table T1 of thedata memory22, stores a new purchase amount of money with the purchase amount of money of this time added to “Purchase Amount of Money”22fin the Table T1, stores a new number of loyalty points with the number of loyalty points calculated this time added to “Number of Loyalty Points”22gin the table T1, and stores the date information of this time for “Adding Date of Loyalty Point”22hof the table T1 (ST57). In addition, theCPU21 outputs information on the loyalty point calculated in Step ST56 to the reader/writer8 (ST58).
• When information of loyalty point that is output from the[0050]IC card7 is input to the reader/writer8 (ST59), the loyalty point is displayed on thedisplay8afor the visual check by a customer who has the IC card (ST60), the IC card is ejected for returning to the customer (ST61), the application change process and the loyalty point adding process are terminated.
• FIG. 9 is a flowchart for explaining the installation of a loyalty point service application to the[0051]IC card7 in connection with the cashing process of loyalty points in the loyalty point system A using theIC card7 set as described above. In this embodiment, when the cashing process of loyalty point recorded in theIC card7 is executed, the loyalty point service application in theIC card7 is changed to another higher loyalty point service application for further increase the service.
• As shown in FIG. 9, when the IC card is first inserted into the[0052]IC card slot8cof the reader/writer8 (ST70), a store clerk selects “Loyalty Point Cashing Process” through thekeyboard8b(ST71). When the loyalty point cashing process is selected in Step ST71, the reader/writer8 first outputs a cashing process command to theIC card7 and becomes the standby state (ST72).
• When the cashing process command is input to the[0053]IC card7 from the reader/writer8 via the contact portion25 (ST73), theCPU21 reads loyalty point information out of “Number of Loyalty Points”22gon the table T1 of the data memory22 (ST74) and outputs it to the reader/writer8 as loyalty point cashing information (ST75).
• When loyalty point cashing information output from the IC card is input, the reader/[0054]writer8 executes a prescribed cashing process for cashing loyalty point information according to the preset loyalty point service application, and returns a service according to the cashing loyalty point to a customer who has the IC card (ST76). Further, the reader/writer8 outputs the loyalty point service changing application to the IC card (ST77).
• When the loyalty point service changing application is input to the[0055]IC card8 from the reader/writer8, theCPU21 updates the loyalty point service application in the data memory22 (ST78). When the application updating in Step ST78 is completed, theCPU21 outputs the information that the application was updated to the reader/writer8 (ST79).
• When information associated with the updating of the application is input from the IC card[0056]7 (ST80), the reader/writer8 displays the completion of the application updating on thedisplay8afor a store clerk (ST81), ejects the IC card for returning to a customer who has the IC card (ST82), and terminates the application change process.
• As described above, this invention is able to calculate a loyalty point in an IC card based on a loyalty point service application which is pre-stored in the IC card memory by inputting purchase information comprising at least purchase amount of money into the IC card. As a result, it has an effect to prevent the forgery of illegal loyalty points.[0057]
• Further, because loyalty service loyalty points are calculated/updated on an IC card, it becomes possible to calculate loyalty points without installing a loyalty point service application to the reader/writer and executing the data processing by the reader/writer. Accordingly, a burden of the data process on the reader/writer can be largely reduced, and it becomes possible to use a cheap reader/writer and contribute to the spread use of the loyalty service point system.[0058]
• Further, as described above, this invention calculates loyalty service points in connection with individual information without obtaining it from an IC card, that is, adds loyalty service points especially in connection with individual information. Therefore, it has an effect that loyalty service points can be added in connection with individual information while retaining its security without leaking individual information to the outside.[0059]
• Further, as described above, this invention is capable of updating the loyalty point service application that is stored in an IC card. Accordingly, it becomes possible to easily change size of loyalty points calculated in an IC card and service objects to which loyalty points are added. Particularly in this embodiment, when the loyalty point cashing process is executed, the loyalty point service application can be changed to another loyalty point service application which is for providing a further improved service including loyalty point ratio or after executing the loyalty point cashing process for an IC card of which term of validity is expired, it can be changed to the loyalty point service application. Accordingly, the service to an IC card holding customer is increased and the spread use/firmly fixing of the loyalty point system.[0060]
• As explained above, according to the present invention, it is possible to calculate loyalty point information and service loyalty points can be calculated corresponding to individual information while holding security.[0061]
