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.
