The invention relates to a method for generating a two-dimensional code and implementing mobile payment by a mobile phone. A user can input various payment card information (such as bank card account numbers, credit card account numbers, prepaid card account numbers, and third party payment user account numbers) into the mobile phone, the information is enciphered and stored, and then the two-dimensional code is generated and displayed on a screen of the mobile phone. A merchant scans a pattern of the two-dimensional code through a two-dimensional code identifying and reading device, and after user authentication information (such as two-dimensional code generation time, mobile phone fingerprints and mobile phone positions) and the payment card information are decoded, the user authentication information, the payment card information, consumption amount information of the user, merchant account number information and the like are enciphered and sent to a corresponding payment and settlement system. After receiving the information, a payment and settlement server confirms the payment card information to be true or false according to the two-dimensional code authentication information, and carries out payment transaction. The method has the main advantage that the user can save the information of various payment cards, consumption cards and the like in the mobile phone and realize no-card electronic payment transaction instead of the various payment cards.

Method for generating two-dimensional code and implementing mobile payment by mobile phone

An embodiment of the invention provides a method and device for generating a two-dimensional code, so as to get rid of dependence on special scanning software, and freely generate the two-dimensional code. The method includes: displaying a two-dimensional code generation interface; receiving to-be-converted information input by a user from an input box and expressed in the form of characters; and in combination with a two-dimensional code generation library, generating the two-dimensional code with the to-be-converted information expressed in the form of characters. The method provided by the embodiment of the invention can enable an application having webpage picture sharing or managing functions to be a generator of the two-dimensional code, and can provide a capability of using a user-defined two-dimensional code to carry out activities of promotion, operation popularization and the like for the application while popularizing a two-dimensional code function. At the same time, the method can be matched with scanning of a local two-dimensional code or a two-dimensional code in a webpage to complete a cycle of generation and use of the two-dimensional code which can be completed by a user by using a mobile phone only, and the two-dimensional code is released from a constraint of needing to depend on a mobile phone lens and various entity pictures, thereby entering the mobile internet industry.

Method and device for generating two-dimensional code

The invention relates to a network control method for a kitchen appliance. The kitchen appliance is provided with a display device, wherein the kitchen appliance registers a cloud server and generates an information code necessary for identifying and controlling the kitchen appliance, the display device displays the information code and accepts a control terminal to scan the information code, and the kitchen appliance pairs with the control terminal through the information code to establish a connection. Since the display device displays the information code, in a use process of a user, the user can control the kitchen appliance by scanning the code via the control terminal, thereby facilitating the operation of the user and avoiding a loss problem when the information code is adhered.

Network control method for kitchen appliance

An exemplary method comprises receiving information associated with a game-playing transaction conducted between a user device and a game-playing terminal, wherein the game-playing transaction is associated with a request for playing a game; determining a location of the user device associated with the game; determining the user device is located in an approved location associated with the game; and processing the game-playing transaction based on determining the user device is located in the approved location associated with the game. The game-playing transaction is conducted on a first communication interface, and the information associated with the game-playing transaction is received on a first or second communication interface.

Processing of a user device game-playing transaction based on location

The invention is suitable for the technical field of communication and provides a contact information exchange method, a contact information exchange system and mobile terminals. The method comprises the following steps of: acquiring local contact information of a first mobile terminal; according to preset rules, carrying out two-dimensional code encoding on the contact information to generate a two-dimensional code name card; and browsing the two-dimensional code name card by a local browser so as to enable a second mobile terminal to acquire information of the two-dimensional code name card. According to the invention, a user of the second mobile terminal can automatically acquire the contact information in the first mobile terminal; the contact information exchange method, the contact information exchange system and the mobile terminals are simple and convenient to operate; the contact information does not need to be manually input to be acquired; and user experience is promoted.

Contact information exchange method, contact information exchange device and mobile terminals

The invention discloses a two-dimension code generation method, a user mobile terminal and a mobile communication system. The two-dimension code generation method comprises the following steps; obtaining text message with a predetermined format through the user mobile terminal; encoding the text message with the predetermined format to generate two-dimension code image information; and preserving the generated two-dimension code image information. By applying the technical scheme provided in the embodiment of the application, the two-dimension code can be automatically generated by the mobile terminal for a user, so that the application range of the two-dimension code in the mobile communication service is extended; and in addition, when the technical scheme of the application is applied to network service, the two-dimension code information with the image format is not required to be transmitted in the communication network, so that the limitation of the own functions of the network transmission mechanism and the mobile terminal to the application of the two-dimension code can be effectively reduced.
