This application discloses a method and device for sending and receiving instruction information. The method for sending instruction information includes: receiving first instruction information and/or operation description information of an operation corresponding to the first instruction information; if the first instruction information is received, temporarily storing the received first instruction information locally; and/or if the operation description information is received, transmitting the operation description information to a mobile terminal; acquiring a first differential signal that is output from a data transmission interface of the mobile terminal and carries the first instruction information and/or the second instruction information; and/or acquiring the first differential signal if a trigger signal sent by the receiving device is received; generating, according to the acquired first differential signal, a first transmission signal that carries the first instruction information, and sending the first transmission signal to the receiving device. |

1. A method for sending instruction information, comprising:
receiving first instruction information and/or operation description information of an operation corresponding to the first instruction information, wherein the operation description information comprises at least one of the following: code information, time information, address information, user information, account information, commodity information, and payment information; if the first instruction information is received, temporarily storing the received first instruction information locally; and/or if the operation description information is received, transmitting the operation description information to a mobile terminal, so that the mobile terminal indicates the operation description information to a user, and so that the mobile terminal generates the first instruction information and/or second instruction information according to input information of the user and/or the operation description information; acquiring a first differential signal that is output from a data transmission interface of the mobile terminal and carries the first instruction information and/or the second instruction information, which specifically comprises: acquiring the first differential signal if a recognition signal indicating that a distance between the mobile terminal and a receiving device is smaller than a preset distance threshold is received; and/or acquiring the first differential signal if a trigger signal sent by the receiving device is received, wherein the first instruction information is used to instruct the receiving device to perform an operation corresponding to the first instruction information, and the second instruction information is used to instruct to send the first instruction information to the receiving device; and generating, according to the acquired first differential signal, a first transmission signal that carries the first instruction information, and sending the first transmission signal to the receiving device, wherein the first transmission signal is a light signal or a sound wave signal. |
