System built by connection between a mobile terminal and a service providing device, and service providing method

The method according to claim 1, wherein:

• corresponding second code information is generated from second service information according to the preset coding rule, and then a corresponding second coding medium is generated from the second code information;
• the second code information is available to any party storing a matched code parsing rule to identify;
• the second service information includes any one or more items of the following:
• payment result after executing the payment operation;
• first identification information, which refers to identification of any one or more of the collaborative background server, the user of the mobile terminal, the mobile terminal, and the service providing device;
• second identification information, which refers to identification information of a third-party user, a third-party mobile terminal, or a third-party server specified by the mobile terminal, the service providing device, or the collaborative background server;
• information correspondingly bound to the first identification information and/or second identification information;
• and
• attribute information corresponding to the user of the mobile terminal, or the mobile terminal, or the service providing device.

The method according to claim 1, wherein:

• the service providing device or the mobile terminal pre-stores a coding medium or its medium carrier;
• the service information corresponding to the coding medium includes the following parameters:
• paid amount, or number of times of consumptions corresponding to the paid amount;
• upon consumption, the service providing device or the mobile terminal releases, or transmits, or displays the coding medium, and any party which identifies the coding medium or successfully parses the corresponding information can obtain the parameter in the service information to write off or update the parameter.

The method according to claim 1, wherein:

• the coding medium or the second coding medium refers to any one of the following or a combination thereof:
• a bar code image generated in a pattern of one-dimensional code, two-dimensional code, or multi-dimensional code;
• an optical lattice diagram generated in a form of light-shadow ray or refurbishing frequency variation or in a form of visible light or UV or infrared light or polarized light;
• and a digitalized acoustic wave or radio wave generated with a specific law or a specific frequency variation pattern.

The method according to claim 1, wherein:

• the collaborative background server includes one or more of the following:
• server of the operator of the service providing device;
• server of the issuer of the service providing device;
• server of the issuer of the code information or its corresponding coding medium;
• server of the operator of the application configured in the service providing device;
• server of the operator of the application configured in the mobile terminal;
• server of the payee;
• and
• server which manages digital currency exchange.
