Member information registration method and system, and member verification method and system

A member information registration system for registering member information in a member database, comprising:

• a data registration means for receiving an individual identifier and verification code outputted from a first device, and registering the received individual identifier and verification code as member data in the member database;
• and
• a data updating means for receiving an individual identifier, verification code, and identification information specific to the second device outputted from a second device, extracting from the member database member data matching both the received individual identifier and the verification code, and adding identification information specific to the second device to the matched member data in the member database.

A member information registration system for registering member information in a member database, comprising:

• a data registration means for receiving from a communication device an individual identifier, verification code, and identification information specific to the communication device, and registering the received individual identifier, verification code, and identification information specific to the communication device as member data in the member database.

A member information registration system, comprising:

• a member database for storing member data including an individual identifier, verification code, and identification information specific to a communication device;
• and
• a data updating means for extracting member data matching both a received individual identifier and verification code from the member database when the individual identifier, the verification code, and identification information specific to the communication device are received from a communication device, and adding the device-specific identification information specific to the communication device to the matched member data in the member database.

A server computer having an on-line shopping providing means for receiving product transaction orders from registered member customers via a computer network, comprising:

• a member database for recording customer data including a customer identification ID, verification code, identification information specific to a communication device used by the customer, and a product transaction history for the customer;
• the member database receiving an identification ID and verification code from a customer, identifying customer data from the received identification ID and verification code when a product transaction order is received, and recording information related to product transaction orders to the product transaction history of the identified customer data, and
• receiving a verification code and communication device-specific identification information from a customer, identifying customer data from the received verification code and communication device-specific identification information when a product transaction order is received, and recording information relating to the product transaction order to the product transaction history of the identified customer data.

A computer readable recording medium on which a program is recorded, the program for causing a computer to function as a member information registration system for registering member information in a member database, which causes the computer to function as the following means:

• a data registration means for receiving an individual identifier and a verification code outputted from a first device, and registering the received individual identifier and verification code as member data in the member database;
• and
• a data updating means for receiving an individual identifier, verification code, and identification information specific to a second device outputted from the second device, extracting from the member database member data matching both the received individual identifier and the verification code, and adding identification information specific to the second device to the matched member data in the member database.
