  • Publication number: 20160277506
    Abstract: A method and an apparatus for one-time connection are provided. In the method, a first apparatus generates a connection item according to first connection information, in which the first connection information is previously registered in a server. Next, a second apparatus obtains the connection item and accordingly generates a virtual card. The second apparatus further uploads the virtual card and second connection information to the server to register the virtual card in the server. Then, the second apparatus receives a selecting operation for the virtual card and accordingly uploads a connection request of using the virtual card to the server. The server establishes a one-time connection between the second apparatus and the first apparatus according to the virtual card, the first connection information and the second connection information.

  • Publication number: 20160078777
    Abstract: An electronic apparatus and a soft locking method thereof are provided. The method is adapted for at least one electronic apparatus. In the method, the at least one electronic apparatus is added to a group and an event is created for the at least one electronic apparatus to participate in. Next, a specific operation performed on each electronic apparatus is detected and a time that all of the at least one electronic apparatus does not detect the specific operation is accumulated. When any one of the at least one electronic apparatus detects the specific operation, the event is suspended and a suspension message is distributed. When the accumulated time reaches a predetermined value, a reward is sent to the at least one electronic apparatus participating in the event.
