Method and device for controlling information transmission, and smart terminal

A smart terminal, comprises:

• a processor;
• and a memory for storing instructions executable by the processor;
• wherein the processor is configured to perform:
• when it is detected that a smart terminal in which a near field communication (NFC) chip is disposed is started, disabling an information output function of the NFC chip;
• after disabling the information output function of the NFC chip, receiving an instruction for outputting information sent by the NFC chip information to be outputted being in an unavailable state;
• performing authentication of an identity of a user who triggers the information output;
• and
• if it is determined that the authentication of the identity is passed, enabling the information output function of the NFC chip and setting the information to be outputted as in an available state, such that the NFC chip can output the information,
• wherein the information to be outputted is information about payment, the information output function of the NFC chip is a card emulation function of NFC, and the card emulation function causes the smart terminal in which the NFC chip is disposed to become a card emulation device for storing information to be read out.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a smart terminal, cause the smart terminal to perform a method for controlling information output, wherein the method comprises:

• when it is detected that a smart terminal in which a near field communication (NFC) chip is disposed is started, disabling an information output function of the NFC chip;
• after disabling the information output function of the NFC chip, receiving an instruction for outputting information sent by the NFC chip, information to be outputted being in an unavailable state;
• performing authentication of an identity of a user who triggers the information output;
• and
• if it is determined that the authentication of the identity is passed, enabling the information output function of the NFC chip and setting the information to be outputted as in an available state, such that the NFC chip can output the information,
• wherein the information to be outputted is information shout payment, the information output function of the NFC chip is a card emulation function of NFC, and the card emulation function causes the smart terminal in which the NFC chip is disposed to become a card emulation device for storing information to be read out.
