BEST MODES FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
First Embodiment
FIG. 1 and FIG. 2 are views showing a pay-by-card system for a home delivery service according to a first embodiment of the present invention.
As shown in FIG. 1, a home delivery contractor 10 enters into an affiliation contract with a credit card company 12 beforehand. Moreover, the home delivery contractor 10 enters into a merchandise price collection consignment contract beforehand with a merchandise seller 14 either of a corporation or an individual who opens a shop in an Internet shopping mall.
Then, if a consumer 16 finds merchandise 18 (see FIG. 2) that the consumer 16 wishes to purchase at the seller 14 who has opened the shop in the Internet shopping mall established on the Internet, for example, then the consumer 16 specifies and orders the merchandise 18. Then the merchandise seller 14 makes a request to the home delivery contractor 10, with whom the merchandise seller 14 has entered into the merchandise price collection consignment contract, for home delivery to deliver the ordered merchandise 18 to the home of the consumer 16.
In this way, as shown in FIG. 2, the home delivery contractor 10 delivers the merchandise 18 to the home of the consumer 16 who ordered the merchandise 18.
Then, the consumer 16 hands a credit card 20, owned by the consumer 16, of the credit card company 12 with whom the home delivery contractor 10 has entered into the affiliation contract, to the home delivery contractor 10 while receiving the merchandise 18 from the home delivery contractor 10.
Then, the home delivery contractor 10 inserts the credit card 20 into a small portable card reader device 22 which he is carrying on site, so as to allow the portable card reader device 22 to read card information recorded on this card, such as an authentication number (a membership number), an expiration date, and the like. Then, the contents of the card record read by the portable card reader device 22 are sent to the credit card company 12 through a communication line such as a telephone line, the Internet, or a wireless line, and a credit inquiry takes place and the price for the delivered merchandise 18 is settled if no problems exists.
When payment of the price for the merchandise 18 is thus completed, the home delivery contractor 10 returns the credit card 20 to the consumer 16.
Accordingly, if the consumer 16 owns the credit card 20, the consumer 16 can enjoy shopping without having to prepare cash equivalent to the price for the merchandise 18 in advance while also being safe since such preparation of cash is not necessary.
On the other hand, for the home delivery contractor 10 since it is not necessary to pass change in such an instance that the consumer 16 passed cash which is more than the price for the merchandise 18, an increase in efficiency of delivery work can be attained. Moreover, since cash management of the received merchandise price and management of change become unnecessary, a risk of loss or theft of the cash also disappears.
Here, as shown in FIG. 1, of the price for the merchandise 18 paid to the credit card company 12, the money amount calculated by offsetting a credit commission to the credit card company 12 will be credited to the home delivery contractor 10, and then the money amount calculated by offsetting a home delivery commission to the home delivery contractor 10 will be credited to the merchandise seller 14.
Note that a settlement contract may be agreed with another settling organization such as a credit loan company or a financial institution instead of the credit card company 12.
Second Embodiment
In the pay-by-card system for a home delivery service according to a second embodiment of the present invention, the home delivery contractor 10 is assumed to be entered into a comprehensive affiliation contract with credit card companies 12 and with credit loan companies or financial institutions collectively as a plurality of settling organizations beforehand. Note that other parts of the constitution are identical to the constitution shown in the first embodiment; accordingly, description thereof will be omitted.
Therefore, when the consumer 16 does shopping in the Internet shopping mall established on the Internet, for example, and there is merchandise 18 that the consumer 16 wishes to purchase at the seller 14 who is an affiliated shop in the Internet shopping mall, then the consumer 16 applies for the merchandise 18 on a screen of a PC.
Then, there appears a selection screen for selecting either credit card settlement or cash-on-delivery settlement as a method of settling the price for the merchandise 18. At this point, the consumer 16 selects the cash-on-delivery settlement and then selects the home delivery contractor 10. In such a case as well, since the home delivery contractor 10 is entered into the affiliation contract with the plurality of credit card companies 12, the consumer 16 can use the credit card 20 he owns at the cash-on-delivery point if he desires credit settlement.
Therefore, the consumer 16 does not have to re-select another home delivery contractor 10 on the PC, with whom the credit card company 12 issuing the credit card owned by the consumer 16 is entered into a contract for an affiliated store, whereby the consumer 16 can specify the home delivery contractor 10 that the consumer 16 uses everyday so as to have certain delivery of the merchandise 18.
Note that other operations and effects are identical to those described in the first embodiment; accordingly, description thereof will be omitted.
Moreover, description has been made in this embodiment regarding the case of performing settlement of the price for the merchandise with the credit card by using the credit company 12. However, it is needless to say that the credit loan company may be also used.
In addition, description has been made in this embodiment regarding the case of performing settlement of the price for the merchandise by using the credit card 20. However, a debit card may be also used. When the debit card is used, the contents recorded in the card being read by the portable card reader device 22 are transmitted to the affiliated financial institution through the communication line and subjected to a credit inquiry, and the price for the delivered merchandise 18 is settled in one lump sum when no problems exist.
Moreover, in the embodiments of the present invention, the home delivery service refers to the act in which a third-party freight forwarder delegated by the seller of the merchandise delivers this merchandise to the home of the consumer.
Third Embodiment
FIG. 3 is an overall view showing a pay-by-card system for a home delivery service according to a third embodiment of the present invention. Note that the third embodiment of the present invention refers to detailed description of the pay-by-card system for a home delivery service according to the first embodiment shown in FIG. 1 and FIG. 2.

The communication processing unit 57 performs communication of information with the host computer 33 through the communication line 31. The display 59 displays inputted contents and messages. The printer 61 prints a receipt upon completion of settlement by card.
Then, a control program is read out of the memory unit 53 into the control unit 55 by turning on a power switch (not shown) provided on the portable card reader device 22, and operation guidance is displayed on the display 59, for example. Accordingly, the home delivery contractor swipes a credit card through the card reader 47 to read the card data out, and the money amount for the merchandise representing the price for the merchandise, and the merchandise identification number are inputted with the keyboard. Next, the tracking number is read out of the bar code by use of the pen reader 49, and the authentication number is inputted with the keyboard 51. Thereafter, the terminal identification number of the portable card reader device being stored in the memory unit 53 in advance is read out. Then, the authentication number, the expiration date, the money amount for the merchandise, the merchandise identification number, the tracking number, and the authentication number are formed into a batch of terminal-collected information, and then the terminal-collected information is transmitted from the communication processing unit 57 to the host computer 33 installed at the information processing center through the communication line 31. Then, when availability information is received from the host computer through the communication processing unit 57, the printer 61 achieves the function of printing a receipt with the tracking number of the merchandise, the credit card company, the money amount for the merchandise, and the like.
Next, as shown in FIG. 5, the host computer 33 is composed of communication processing units 63, a communication control unit 65, communication processing units 67, a communication control unit 69, a control unit 71, and a storage unit 73.

Moreover, when the terminal-collected information from the portable card reader device 22 is received by the communication processing unit 63 through the communication line 31, the control unit 71 stores this terminal-collected information into the database of the storage unit 73, and transmits a request for a credit check with the attached of the authentication number and the expiration date of the relevant consumer from the communication processing unit 67 to the settlement server 37 installed at the credit card company through the communication line 35.
Thereafter, when confirmation information from the settlement server 37 installed at the credit card company is received by the communication processing unit 67, the control unit 71 stores either the availability information or unavailability information contained in this confirmation information as the card information corresponding to the relevant tracking number in the database, and then transmits this confirmation information from the communication processing unit 63 to the portable card reader device 22 through the communication line 31.
Simultaneously, the control unit 71 deletes the authentication number of the credit card, which is stored in the database, provided in the storage unit 73. In this way, since the authentication number of the credit card being temporarily stored in the storage unit 73 is deleted, it is possible to prevent leakage of important personal information.
Furthermore, at a predetermined time arranged between the credit card company and the home delivery contractor for transferring the contents of the database, the control unit 71 transfers the contents of storage accumulated in the database of the storage unit 73 from the communication processing unit 67 to the home delivery management server 39 installed at the home delivery contractor through the communication line 35. Here, the control unit 71 performs the following functions of: reading the card information on the database of the storage unit 73; reading the money amount for the merchandise (the price for the merchandise) in the transaction information when the availability information is contained in the confirmation information; and transmitting a money amount (A), which is calculated by deducting a credit commission from the money amount for the merchandise, to the settlement server 41 installed at the financial institution which has entered into the settlement contract with the home delivery contractor.
Next, as shown in FIG. 7, the home delivery management server 39 is composed of communication processing units 75, a communication control unit 77, a control unit 79, a display control unit 81, and a storage unit 87.

Next, description will be made regarding operations of the pay-by-card system for a home delivery service according to the third embodiment of the present invention with reference to flowcharts shown in FIG. 9 to FIG. 11 and a sequence chart shown in FIG. 12. Note that the flowchart of the portable card reader device shown in FIG. 9 is stored in the control unit 55 as a program. Moreover, the flowchart of the host computer shown in FIG. 10 is stored in the control unit 71 as a program. Furthermore, the flowchart of the home delivery management server shown in FIG. 11 is stored in the control unit 79 as a program.
Similar to the first embodiment, in the third embodiment as well the home delivery contractor 11 enters into an affiliation contract with the credit card company 12 beforehand. Moreover, the home delivery contractor 10 enters into a merchandise price collection consignment contract with the merchandise seller 14 either of a corporation or an individual beforehand.
Moreover, if the consumer 16 specifies and orders with the seller 14 the merchandise 18 that the consumer 16 wishes to purchase, for example, then the merchandise seller 14 makes a request to the home delivery contractor 10, with whom the merchandise seller 14 has entered into the merchandise price collection consignment contract for home delivery, to deliver the ordered merchandise 18 to the home of the consumer 16.
In this way, as shown in FIG. 2, the home delivery contractor 10 delivers the merchandise 18 to the home of the consumer 16.
Then, the consumer 16 hands the credit card 20, owned by the consumer 16, of the credit card company 12 with whom the home delivery contractor 10 has entered into the affiliation contract, to the home delivery contractor 10 while receiving the merchandise 18 from the home delivery contractor 10.
Then, the home delivery contractor 10 inserts the credit card 20 into the small portable card reader device 22 having the portable card reader device 47 which he is carrying on site, allowing the information recorded on the card to be read.
Now, with reference to FIG. 9, in Step K10, the card reader 47 reads the card information including the authentication number, the expiration date and the like for identifying the member recorded on the card 20, and the card information is temporarily stored in the internal RAM provided in the memory unit 53 through the control unit 55.
Then, in Step K20, as the home delivery contractor 10 inputs the money amount for the merchandise with the keyboard 51, this money amount for the merchandise is temporarily stored from the control unit 55 into the internal RAM of the memory unit 53.
Then, in Step K30, as the home delivery contractor 10 inputs with the keyboard the merchandise identification number for identifying the merchandise, such as the price for the merchandise or a transportation charge 51, this merchandise identification number is temporarily stored from the control unit 55 into the internal RAM of the memory unit 53.
Then, in Step K40, as the home delivery contractor 10 reads the tracking number of the merchandise out of the bar code written on part of the tag by use of the pen reader 49, this tracking number is temporarily stored from the control unit 55 into the internal RAM of the memory unit 53.
Then, in Step K50, as the home delivery contractor 10 inputs with the keyboard 51 the authentication number shown on the card 20, this authentication number is temporarily stored from the control unit 55 into the internal RAM of the memory unit 53.
Then, in Step K60, the control unit 55 reads the terminal identification number of the portable card reader device 22, which is stored in the memory unit 53 in advance. In addition, the control unit 55 respectively reads the card information such as the authentication number and the expiration date, the money amount for the merchandise, the merchandise identification number, the tracking number and the authentication number which have been temporarily stored in the internal RAM, and then forms these pieces of information into a batch of terminal-collected information. Then, the control unit 55 transmits the terminal-collected information to the host computer 33 installed at the information processing center through the communication line 31.
Moving to FIG. 10, the control unit 71 of the host computer 33, which received the terminal-collected information from the portable card reader device 22 through the communication line 33, stores this terminal-collected information in the database of the storage unit 73 in Step H10 as shown in FIG. 6.
Then, in Step H20, the request for a credit check with the attached authentication number and the expiration date of the consumer is transmitted to the settlement server 37 installed at the credit card company through the communication line 35.
The settlement server 37 installed at the credit company, which receives the request for a credit check from the host computer 33, searches and compares as to whether or not the authentication number and the expiration date attached to this request for a credit check matches with the authentication number allotted to the consumer in order to judge validity of the given credit card being stored in a database (not shown) provided in its own server, whereby the settlement server 37 judges as to whether or not this consumer has a status where the consumer is currently entered into a credit contract with the relevant credit card company and the credit card is usable. Then, the settlement server 37 generates the confirmation information containing the availability information if the credit contract concerning this consumer is valid. On the contrary, if the credit contract concerning this consumer is not valid, then the settlement server 37 generates the confirmation information (the result of the credit inquiry) containing the unavailability information. Thereafter, the settlement server 37 returns the confirmation information thus generated back to the host computer 33.
In Step H30, the control unit 71 of the host computer 33, which received the confirmation information from the settlement server 37 installed at the credit card company, stores either the availability information or the unavailability information contained in this confirmation information as the card information corresponding to the relevant tracking number in the database.
Then, in Step H40, the host computer 33 transmits this confirmation information to the portable card reader device 22 through the communication line 31. Simultaneously, in Step H50, the control unit 71 deletes the authentication number of the credit card stored in the database provided in the storage unit 73, and then the process goes to Step H60.
As a result, because the authentication number of the credit card temporarily stored in the storage unit 73 is deleted after obtaining the result of the credit inquiry it is possible to prevent leakage of important personal information on the consumer.
In this way, if the host computer 33 installed at the information processing center receives the authentication number of the consumer and the information on the money amount for the merchandise through the communication line 31 by use of the portable card reader device 22 carried by the home delivery contractor and the host computer 33 transmits this authentication number to the settlement server 37 of the credit card company which performs settlement on behalf of the consumer, and if the host computer 33 receives the confirmation information indicating availability with this credit card company from the settlement server 37 of the credit card company, then the host computer 33 transmits this confirmation information to the portable card reader device 22. Thus, it is possible to carry out the credit inquiry concerning the card which is read by the portable card reader device 22.
Moving to FIG. 9, in Step K70, the portable card reader device 22 stands by until the portable card reader device 22 receives the confirmation information from the host computer 33. Here, the portable card reader device 22 goes to Step K80 upon receipt of the confirmation information from the host computer 33, and judges as to whether or not the credit card company is available based on this confirmation information. That is, the credit card company is available if the availability information is contained in the confirmation information. In this case, the process goes to Step K100. On the contrary, the credit card company is not available if the unavailability information is contained in the confirmation information. In this case, the process goes to Step K90.
When the credit card company is not available, in Step K90, the control unit 55 reads message information such as “This credit card company is not available” out of the memory unit 53, and displays an error message on the display 59. Simultaneously, the control unit 55 deletes the card information, such as the authentication number and the expiration of the consumer, which has been temporarily stored in the internal RAM of the memory unit 53. Then, the process goes back to Step K10 and the above-described processing is repeated.
On the other hand, when the credit card company is available, in Step K100, the control unit 55 reads the tracking number of the merchandise, the credit card company, the money amount for the merchandise, and the like out of the memory unit 53. Then, the control unit 55 generates receipt information representing completion of settlement of the merchandise, by attaching the time read out of the timer to the above data as the date and time of delivery. This receipt information is outputted to the printer 61, whereby a receipt is printed out.
Simultaneously, the control unit 55 deletes the card information of the consumer, such as the authentication number and the expiration, which has been temporarily stored in the internal RAM of the memory unit 53. Then, the process of the portable card reader device 22 is finished. The printed receipt is torn from the printer 61 by the home delivery contractor and is passed to the consumer.
In this way, the authentication number of the consumer is read out of the credit card issued by the credit company which performs settlement on behalf of the consumer, and information on amount of the money for the merchandise ordered by the consumer is also inputted. Then, when the authentication number of the consumer and the information on the money amount for the merchandise are transmitted to the host computer 33 of the information processing center through the communication line, and when the information indicating availability of the credit card company is received from the host computer 33 of the information processing center, the receipt representing completion of settlement of the merchandise is printed out of the printer 61. For this reason, it is possible to settle the price for the merchandise delivered by the home delivery service with the credit card. As a result, the consumer who ordered the merchandise can purchase the delivered merchandise on credit without having to prepare the cash equivalent to the price for the merchandise to be delivered, enjoy shopping, and a contribution can be made to the convenience and safety of the consumer.
Moreover, in the portable card reader device 22, the authentication number of the credit card being temporarily stored in the storage unit 73 is deleted after obtaining the result of the credit inquiry. Accordingly, it is possible to prevent leakage of the important personal information on the consumer.
Here, in Step H60, the control unit 71 of the host computer installed at the information processing center judges as whether or not the time being read out of the timer is the predetermined time arranged between the credit card company and the home delivery contractor for transferring the contents of the database. Then, the process goes back to Step H10 until the predetermined time, and the above-described processing is repeated.
When it is the predetermined time, in Step H70, the contents of storage accumulated in the database of the storage unit 73 are transferred to the home delivery management server 39 installed at the home delivery contractor through the communication line 35.
Then, in Step H80, the control unit 71 reads the card information on the database of the storage unit 73, and judges as to whether or not the availability information is contained in the confirmation information. Thereafter, when the availability information is contained therein, the control unit 71 reads the money amount for the merchandise (the price for the merchandise) in the transaction information, then transmits the money amount (A) calculated by deducting the credit commission from this money amount for the merchandise to the settlement server 41 installed at the financial institution which has entered into the settlement contract with the home delivery contractor, and then the processing is finished.
As a result, the credit commission will be credited to the credit card company by the end of a predetermined due date, and further, monthly payment of the price for the merchandise will be credited every month. Moreover, the money amount (A) is credited from the credit card company to the financial institution that has entered into the settlement contract with the home delivery contractor.
As described above, the host computer 33 returns the information on the money amount for the merchandise if the host computer 33 has received the confirmation information which indicates availability with this credit card company, from the settlement server 37 of the credit card company which performs the settlement on behalf of the consumer. Moreover, by transmitting a request of payment for the money amount for the merchandise from the credit card company to the settlement server 41 of the financial institution that performs the settlement on behalf of the home delivery contractor, the cash-on-delivery settlement of the merchandise can be carried out through the credit card company, and the price for the merchandise can be paid to the financial institution that performs the settlement on behalf of the home delivery contractor.
Moreover, the settlement server 37 of the credit card company which performs the settlement on behalf of the consumer transfers the money amount (A) calculated by deducting the commission concerning the settlement from the money amount for the merchandise to the financial institution which performs the settlement on behalf of the home delivery contractor. Accordingly, the credit card company can record the sale while settling the commission concerning the settlement.
Moving to FIG. 11, in Step T10, the control unit 79 of the home delivery management server 39 installed at the home delivery contractor stores the database storage contents received from the host computer 33 installed at the information processing center, into the database of the storage unit 87.
Then, in Step T20, judgment is made as to whether or not it is the predetermined time arranged between the credit card company and the home delivery contractor. Then, the process goes back to Step T20 until the predetermined time, and the above-described processing is repeated.
When it is the predetermined time, in Step T30, the request for inquiring an account balance is transmitted to the settlement server 41 of the financial institution which has entered into the settlement contract with the home delivery contractor.
Then, in Step T40, the home delivery management server 89 stores the account information received from the settlement server 41 of the financial institution so as to correspond to the tracking number in the database of the storage unit 87.
Then, in Step T50, the control unit 87 checks as to whether or not the money amount (A) has been credited for the merchandise from the credit card company with respect to the account information corresponding to each tracking number stored in the data base. Then, in Step T60, the deposited amount (A) in the account information of the database is read out when the money amount (A) has been credited for the merchandise from the credit card company, and the money amount (B) calculated by deducting the home delivery commission from this deposited amount (A) is transmitted to the settlement server 43 installed at the financial institution which has entered into the settlement contract with the seller, and then the processing is finished.
As a result, the money amount (B), that is, the money amount (B) calculated by deducting the credit commission and the home delivery commission from the money amount for the merchandise is credited to the financial institution which has entered into the settlement contract with the seller.
Note that description has been made in the third embodiment based on the example of performing the credit card settlement with the credit card issued by the credit card company, which is the settling organization that performs the settlement on behalf of the consumer. However, the settling organization may be other financial institutions such as a bank. In this case, the consumer can perform cash-on-delivery settlement in response to the delivered merchandise with a debit card issued by the financial institution. Here, in the case of settling by use of the debit card, the consumer is supposed to input a personal identification number which has been registered with the financial institution beforehand.
Meanwhile, in addition to the above-described credit card and the debit card, there are other individually inherent authentication media such as fingerprints and retinas. If image information is read from fingerprints or retinas and is registered with the settling organization beforehand, and if this image information is read with the portable card reader device 22 and the authentication processing is performed by the settling organization, then it is possible to specify an individual.
