Disclosed is a data card, comprising a casing, a PCB and a main antenna arranged in the internal cavity of the casing, and an adapter fixedly connected to the casing. The data card also comprises a metal rotating shaft for an adapter which is arranged in the casing and electrically connected to the adapter. The metal rotating shaft for an adapter and the adapter form a diversity an antenna of the data card. Also disclosed is a data interaction system comprising a data card and a user terminal. By means of the solution disclosed in the present invention, since a diversity antenna need not be independently arranged, the overall dimensions of a data card are reduced, and the appearance of the data card is ensured, thereby reducing the production cost of the data card. |
