Abstract: A device and method are provided. The device includes a controller, a memory, and a transceiver. The controller generates authentication information based on a user input to the device. The memory stores the generated authentication information. The transceiver receives authentication information, which is generated by a point of sale (POS) terminal based on a user input to the POS terminal, from the POS terminal, when the device enters within a predetermined range from the POS terminal. The controller compares the generated authentication information with the received authentication information, and provides card information which is used in a transaction with respect to an item or a service to the POS terminal based on a result of the comparison.

Abstract: An apparatus and a method for sharing contents provided based on a social network between members of the social network. A content providing method includes, when a first terminal in a social network requests to use content, transmitting the corresponding content to the first terminal. The method also includes transmitting content use information associated with the first terminal to at least one adjacent terminal in the social network, via the social network. The method further includes, when a second terminal of the at least one adjacent terminal requests to use the same content as the first terminal, transmitting the same content to the second terminal.
