Abstract: Systems and methods are disclosed for tracking and utilizing data tag carriers involving a plurality of terminals, and associated data tags and data tag carriers. A first terminal obtains an initial data tag from an initial data tag carrier. The initial data tag includes initial service processing information and information about the initial data tag carrier. A first data tag carrier group is coupled to the first terminal and comprising at least one first data tag carrier. The first data tag carrier group obtains the initial data tag from the first terminal and to release the first data tag through the first data tag carrier. The first data tag includes a first service processing information, information about the first terminal and the first data tag carrier. The disclosed systems and methods are simple, easy to implement, and of low cost.

Abstract: The present invention relates to a method and system that use data tags to track tasks in applications to provide Object-to-Object (OTO) services. A first application data tag is issued by a data tag server as in an OTO service platform in response to an initiation of a first application by a first initiator. The first data tag specifies at least one first task for fulfilling a first service. The first application data tag is scanned by a first user terminal by a first participant. A first action data tag is issued by the data tag server. A first dynamically variable task data tag is issued by the data tag server to track the first task in the first action. The first dynamically variable task data tag is updated to record the completion of the first task in the first action when the first task is completed.

Abstract: The present invention relates to a method and system for data tagging in the field of computer technologies. In this method, a user terminal acquires tag data, obtains information about services and functions associated with the tag data, then interacts with target servers to exchange service and function information, and fulfills appropriate services and functions to complete the business application. The disclosed data tagging method and system allow user terminal to interact with directly target servers that are associated with relevant services and functions, which allows functions to be realized in distributed target servers, which simplifies the implementations of tag data, reducing the cost to setting servers. The disclosed data tagging methods allow more extensive applications of data tagging, improved user experiences, simplified processes, and lower costs.
