Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The descriptions in the various embodiments are only shown and limited by way of example and without intention other than the intention to help those of ordinary skill in the art to more thoroughly understand the present invention, and thus the scope of the present invention. It should not be used as a limitation.

1 is a conceptual diagram of a customer information changing system according to the present invention, and FIG. 2 is a flowchart showing a customer information changing system and a method thereof according to the present invention.

1 and 2 will be described in detail the basic concept and process of the customer information change system and method according to the present invention.

As shown in Figures 1 and 2, the customer information change system according to the present invention includes at least one or more users (or customers, 100), customer information centralized server 200, and at least one member company (200) The customer information intensive server 200, the at least one user 100, and the member companies 300 are connected to each other through a communication network capable of transmitting and receiving data.

The user 100 includes at least one customer or potential prospective customer of the member companies 300, and may use the customer information changing service by registering with the customer information intensive server.

The user 100 may use the customer information changing service of the customer information intensive server by registering with the customer information intensive server, and register with the customer information intensive server in association with being registered with the member company to perform the customer information changing service. It can also be used.

In addition, the user 100 may include a terminal capable of transmitting and receiving data, that is, a terminal such as a computer, a mobile phone, or a PDA.

The member company 300 may be a financial institution such as a bank, a card company or an insurance company, may be a communication agency such as a mobile communication company or a wired or wireless communication company, may be a public institution such as Korea Electric Power Corporation, Korea Gas Corporation or Korea Highway Corporation. , An online shopping mall company, a search site company, an online advertising company, a content provider or an online game company.

In addition, the member company 300 may be provided with a server or computer that the users can transmit and receive data and process.

The configuration and operation of the customer information concentration server 200 will be described in more detail in the following description of FIGS. 3 to 6.

According to such a customer information change system, when the user's personal information is changed, the user 100 is connected to the customer information concentration server 200 connected through a communication network to change the customer information only once by the member companies 300 All changed customer information is provided. Therefore, it eliminates the inconvenience of changing the customer information individually to all registered member companies, there is an advantage that can accurately change their customer information.

Similarly, when the member companies 300 change the customer information of the users, the changed customer information is automatically provided to the corresponding users by registering the changed customer information in the customer information concentration server.

Hereinafter, a process of changing customer information using the customer information changing system will be described in more detail with reference to the flowchart of FIG. 2. For better understanding, the first embodiment (1) represented by a solid line represents a process of changing customer information when the user wants to change customer information, and the second embodiment (2) represented by a dotted line represents a member company. It shows the process of changing customer information in case of changing the information.

If the user 100 wants to correct his or her personal information, such as name, home address, home phone number, mobile phone number, work, work address, e-mail address, or is incorrectly entered, access the customer information concentration server and Request for information change and input changed customer information after undergoing a predetermined identity verification process (1-1).

When the customer information intensive server registers the changed customer information and provides the changed customer information to each member company (1-2), each member company changes and processes the customer information and provides the processing result back to the customer information intensive server ( 1-3).

The customer information intensive server notifies the user (1-4) of the processing result by e-mail or SMS. The user checks the processing result and if there is a modification, accesses the customer information intensive server again and changes the customer information in the same process.

On the other hand, the member company registers new customer information or changes the customer information, such as adjusting credit or membership level, providing or destroying coupons, increasing or decreasing points, changing purchases, or changing credit information. In the case where the changed customer information is registered in the customer information intensive server (2-1), the customer information intensive server notifies the user of the changed customer information by using e-mail or SMS (2-2).

When the user checks the changed customer information (2-3), the customer information intensive server notifies the member company of the confirmation of the customer information, and if the user does not confirm or return the changed customer information, such contact status information is returned. Notify member companies (2-4).

The contact status information is information about the information sent by the customer information intensive server or the member companies, for example, a mail was sent but returned, a call was made but an incorrect phone number, or an e-mail was sent. Status information, such as when a mail fails to send due to an e-mail address or absence of the e-mail address.

As such, the customer information intensive server continuously checks the contact status information to the member companies so as to check in real time whether the customer information is accurate.

In addition, the contact status information may be included in the customer information and provided to the member company when the customer information is changed or periodically.

After the user 100 checks the changed customer information, if the customer information needs to be changed or corrected, the user information may be changed by accessing the customer information intensive server 200 and undergoing the above-described change process.
