Method and device for locking electronic payment application

Abstract

The invention discloses a method for locking electronic payment application. The method comprises the following steps that: when the electronic payment application is not used within a predetermined application time interval, a mobile terminal transmits an electronic payment application locking request to a smart card; and the smart card locks the electronic payment application when receiving the electronic payment application locking request. The invention also provides a device for locking the electronic payment application, which comprises the mobile terminal and the smart card, wherein the mobile terminal is used for transmitting the electronic payment application locking request and an electronic payment application unlocking request to the smart card, and the smart card is used for locking or unlocking the electronic payment application after receiving the requests transmitted by the mobile terminal. By adopting the method and the device of the invention, the safety of the electronic payment information and the economy of a user can be guaranteed.

Description

technical field [0001] The present invention relates to near field communication (NFC, Near Field Communication) technology, in particular to a method and device for locking an electronic payment application. Background technique [0002] NFC technology is a short-range wireless communication technology working at 13.56MHz, which evolved from the integration of non-contact radio frequency identification (RFID, Radio Frequency Identification) and interconnection technology. Integrating NFC on the mobile terminal can enable the mobile terminal to have an electronic payment function, that is, as long as the mobile terminal is scanned in front of the NFC terminal reader, the payment can be conveniently completed. Here, the integrated NFC is used on the mobile terminal, that is, an NFC analog front-end chip, an NFC antenna, and a smart card with a built-in electronic payment application are added to the terminal; wherein, the smart card is connected to the NFC analog front-end ch...

Problems solved by technology

[0003] The application of mobile terminals to electronic payment expands the scope of use of mobile terminals, which can bring convenience to consumers' lives, stimulate consumer consumption, and bring business opportunities to wireless operators, retailers and mobile phone manufacturers, with broad prospects; but At present, there are no security measures for mobile terminal electronic payment applications. In this way, after the mobile terminal is lost, the person who gets the mobile terminal can pay through the smart card, which will bring economic losses to the user and cause the user to be stored in the smart card on the mobile terminal. The leakage of electronic payment information such as bank account information, credit card account information, etc. makes users have to worry about their own electronic payment information and economic security while enjoying the convenience brought by electronic payment applications on mobile terminals.
