Electronic receipt management system
A distributed computer system includes a central server, a computing device of a user, and point-of-sale terminals. The central server is configured to assign a global user ID to a user and store, in association with the global user ID, local user IDs. The computing device is configured to generate and display a code symbol representing at least one user ID. A point-of-sale terminal is configured to scan the displayed code symbol and code symbols of merchandise being purchased, and generate transaction information. A local server is configured to transfer the transaction information from the point-of-sale terminal to the central server. When the transaction information includes a local user ID, a point total of the user is updated based on the transaction information and transmitted to the computing device. The central server stores the transaction information, which is received from the local server, in association with the global user ID.
1. A mobile terminal of a user, comprising:
a display device;
an imaging device;
a memory that stores:
an electronic receipt user ID, and
a plurality of member IDs each associated with a store code; and
a processor configured to
when a user logs into the mobile terminal, encode the electronic receipt user ID into a first symbol and control the display device to display an image of the first symbol, and
when an image of a second symbol displayed in a store and indicating a store code is acquired by the imaging device,
decode the second symbol into the store code and retrieve from the memory one of the member IDs associated with the store code,
generate an image of a third symbol indicating said one of the member IDs, and
control the display device to display the generated image of the third symbol instead of the image of the first symbol, wherein
a point-of-sale (POS) terminal of the store uses:
the image of the first symbol to generate information for an electronic receipt, the information including the electronic receipt user ID, and
the generated image of the third symbol to identify the user as a member of the store.
2. The mobile terminal according to claim 1 , wherein
upon receipt of a notification indicating that the electronic receipt is received, from a server via a first network before receiving the electronic receipt, the processor controls the display device to display the notification.
3. The mobile terminal according to claim 2 , wherein
the server is an electronic receipt management server configured to receive the electronic receipt from a store server via a second network that is different from the first network.
4. The mobile terminal according to claim 3 , wherein
the electronic receipt is transmitted from the store server via an electronic receipt server configured to communicate with both the electronic receipt management server and the store server.
5. The mobile terminal according to claim 2 , further comprising:
a network interface, wherein
upon receipt of a predetermined input by a user via an input device, the processor controls the network interface to transmit a request for the electronic receipt to the server.
6. The mobile terminal according to claim 1 , wherein
the processor is further configured to, upon receipt of the electronic receipt from a server, control the display device to display the electronic receipt, and
the image of the third symbol is displayed in a screen through which a request for the electronic receipt can be sent.
7. A mobile terminal according to claim 1 , wherein the processor is further configured to, after retrieving said one of the member IDs:
generate an image of a symbol indicating both said one of the member IDs and the electronic receipt user ID, and
control the display device to display the generated image.
8. A non-transitory computer readable medium storing a program causing a mobile terminal of a user to execute a method comprising:
storing in a memory:
an electronic receipt user ID, and
a plurality of member IDs each associated with a store code;
when a user logs into the mobile terminal, encoding the electronic receipt user ID into a first symbol and displaying an image of the first symbol;
when an image of a second symbol displayed in a store and indicating a store code is acquired,
decoding the second symbol into the store code and retrieving from the memory one of the member IDs associated with the store code;
generating an image of a third symbol indicating said one of the member IDs; and
displaying the generated image of the third symbol instead of the image of the first symbol, wherein
a point-of-sale (POS) terminal of the store uses:
the image of the first symbol to generate information for an electronic receipt, the information including the electronic receipt user ID, and
the generated image of the third symbol to identify the user as a member of the store.
9. The computer readable medium according to claim 8 , wherein
the method further comprises:
upon receipt of a notification indicating that the electronic receipt is received, from a server via a first network before receiving the electronic receipt, displaying the notification.
10. The computer readable medium according to claim 9 , wherein
the server is an electronic receipt management server configured to receive the electronic receipt from a store server via a second network that is different from the first network.
11. The computer readable medium according to claim 10 , wherein
the electronic receipt is transmitted from the store server via an electronic receipt server configured to communicate with both the electronic receipt management server and the store server.
12. The computer readable medium according to claim 8 ,
wherein
the method further comprises, upon receipt of an electronic receipt from a server via a wireless network interface, displaying the electronic receipt on a display, and
the image of the third symbol is displayed in a screen through which a request for the electronic receipt can be sent.
13. A method performed by a mobile terminal of a user, comprising:
storing in a memory:
an electronic receipt user ID, and
a plurality of member IDs each associated with a store code;
when a user logs into the mobile terminal, encoding the electronic receipt user ID into a first symbol and displaying an image of the first symbol;
when an image of a second symbol displayed in a store and indicating a store code is acquired,
decoding the second symbol into the store code and retrieving from the memory one of the member IDs associated with the store code;
generating an image of a third symbol indicating said one of the member IDs; and
displaying the image of the third symbol instead of the image of the first symbol, wherein
a point-of-sale (POS) terminal of the store uses:
the image of the first symbol to generate information for an electronic receipt, the information including the electronic receipt user ID, and
the generated image of the third symbol to identify the user as a member of the store.
14. The method according to claim 13 , further comprising:
upon receipt of an electronic receipt from a server via a wireless network interface, displaying the electronic receipt on a display, wherein
the image of the third symbol is displayed in a screen through which a request for the electronic receipt can be sent.
