NFC payment method, device, system and mobile terminal

Abstract

The invention discloses an NFC payment method. The method includes the steps that a first terminal receives input transaction data and NFC transaction instructions according to received outer instructions and outputs second information; a mobile terminal receives a radio frequency signal which is received from the first terminal and used for activating NFC payment; the mobile terminal is initialized according to initialization data from the first terminal, sends an initialization completion response to the first terminal and outputs first information; the mobile terminal collects biological characteristics of a user to obtain an image of the biological characteristics and carries out image process to extract first biological characteristic values; the mobile terminal compares the first biological characteristic values with second biological characteristic values included by pre-stored user information, and sends an authentication successful response to the first terminal when the first biological characteristic values are consistent with the second biological characteristic values; the first terminal interacts with a first server and the mobile terminal to complete NFC payment. According to the NFC payment method, the device, the mobile terminal and the system, safety can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an NFC payment method, an NFC payment device, an NFC payment system and a mobile terminal. Background technique [0002] Near Field Communication (NFC) is a short-range wireless communication technology that allows short-distance non-contact point-to-point data transmission between electronic devices. NFC payment is based on NFC technology, through mobile terminals, such as mobile phones, tablets, etc., to complete electronic currency payment. [0003] For convenience and quickness, small NFC payments usually do not require user confirmation, so there is a risk of being swiped maliciously. For example, the existing NFC payment prompts the user to make NFC payment through sound and / or vibration, which has good human-computer interaction. However, in a noisy and crowded environment, users are often unable to perceive such prompts, and functions such as text messages an...

[0003] For convenience and quickness, small NFC payments usually do not require user confirmation, so there is a risk of being swiped maliciously. For example, the existing NFC payment prompts the user to make NFC payment through sound and / or vibration, which has good human-computer interaction. However, in a noisy and crowded environment, users are often unable to perceive such prompts, and functions such as text messages and phone calls also prompt users through sound and / or vibration, causing users to become accustomed to sound and vibration prompts, which gives criminals an opportunity

[0004] At present, although the password confirmation method or fingerprint confirmation method can be used to prevent the occurrence of the above-mentioned stolen swiping, there are still cases where the password and fingerprint are stolen and the card is swiped maliciously.
