Abstract
Description
The present invention relates to a financial service system and method using short-range wireless communication. More specifically, the financial information used for payment using short-range wireless communication such as NFC may be used as virtual virtual card information with a limited number of times of use and a period of use. Alternatively, the present invention relates to a financial service system and method using short-range wireless communication that can improve the security level of financial services by preventing the financial information of the user from being leaked by continuously changing the financial related information stored in the user terminal. .
BACKGROUND ART A technology for providing a financial service by adding a payment function to a mobile communication terminal such as a smartphone, a tablet, a PDA, and the like has become common.
One example is using a Subscriber Identity Module (SIM). A SIM card is a type of IC card inserted and mounted in a mobile communication terminal. The SIM card stores credit card information issued by a financial institution in a SIM card and performs a financial transaction through wireless communication using the information stored in the SIM card.
Meanwhile, the universal subscriber identity module (USIM) installed in the third generation mobile communication terminal is a combination of a subscriber identity module (SIM) card and a universal IC card (UICC), and can implement various functions such as user authentication, global roaming, and e-commerce. have.
When providing a financial service using a USIM card, an OTA (Over The Air) service is used. The OTA service can store or update data in the USIM via the infrastructure of the mobile communication terminal. The OTA service can store and use an encrypted card number in the USIM in an OTA manner. However, the card number stored in the USIM is unique information used when paying for the card, and may cause a problem in security when the USIM or the terminal equipped with the USIM is lost. In addition, there is a risk of hacking because the card number is transmitted to the payment terminal as it is when using the USIM.
Recently, various types of financial transaction systems using near field communication (NFC) have been developed. NFC is a technology that transmits period data at a short distance of about 10 cm using a frequency band of 13.56 MHz, and can transmit data in two directions, and can be applied to various fields such as mobile finance, payment, and user authentication. Therefore, a consensus has been formed that more convenient financial transactions can be made by actively utilizing the advantages of NFC, and development of various types of financial transaction systems using NFC has been called for.
The present invention has been made in order to solve the above-described problems, the financial information used for payment using short-range wireless communication such as NFC is stored in the user terminal by replacing the number of times of use, variable virtual card information with a limited use period There is a technical problem to provide a financial service system and method using short-range wireless communication that can improve the security level of financial services by preventing the leakage of financial information of the user by constantly changing the financial-related information.
According to an aspect of the present invention for solving the above problems, the card company server for storing and managing the user information and card information of the user who issued the card; A user terminal having a short range wireless communication function, requesting virtual card information to be used for payment using the card, storing the received virtual card information, and transmitting the virtual card information in a short range wireless communication method during card payment; And receiving and storing the user information and the card information from the card company server, and searching the user information and the card information to provide the virtual card information to the corresponding user terminal when the virtual card information request is received from the user terminal. Provided is a financial service system using near field communication including an intermediary server.
According to another aspect of the present invention for solving the above problems, the step of storing the user information and issued card information of the user who issued the card in the card company server and transmitting the user information and the card information to the mediation server; Receiving and storing the user information and the card information in the relay server; Requesting virtual card information from the user terminal at the intermediate server; Retrieving the user information and the card information and providing the virtual card information to the corresponding user terminal when receiving the virtual card information request from the relay server; And receiving and storing the virtual card information at the user terminal, and transmitting the virtual card information in a short range wireless communication method when the card is settled.
According to the financial service system and method using the short-range wireless communication of the present invention as described above, by replacing the financial information used for payment using the short-range wireless communication such as NFC with variable virtual card information with a limited number of times of use and use period In addition, the financial information stored in the user terminal may be continuously changed, thereby preventing the user's financial information from being leaked, thereby improving the security level of the financial service.
