Abstract: An electronic device and related operations are disclosed, including a communication circuit, a memory and a magnetic stripe transmission (MST) module for radiating a magnetic pulse. A processor implements the operations, including: controlling the MST module to change an emitted radiation pattern of the magnetic pulse in prespecified order to iteratively emit the plurality of radiation patterns, in response to detecting a prespecified event, selecting a presently emitted radiation pattern of the magnetic pulse, and storing information corresponding to the selected radiation pattern in the memory, or transmitting the information corresponding to the selected radiation pattern to the server.

Abstract: An electronic device is provided. The electronic device includes a first wireless communication circuit that establishes a first wireless connection with an external mobile device, a second wireless communication circuit that wirelessly accesses an internet, a user interface, a processor, and a memory. The memory stores instructions that, when executed, cause the processor to, when a payment request occurs while the first wireless connection is interrupted, receive a user input, in response to receiving the user input, perform user authentication, when the user authentication is successful, transmit a first request for an authentication token to a first external server, receive a first response including the authentication token from the first external server, after receiving the first response, transmit a second request for a transaction token to the external mobile device, and receive a second response including the transaction token from the external mobile device.

Abstract: In a Voice over Internet Protocol (VoIP) video communication method and apparatus, first and second VoIP-based terminals store video event indexes and images mapped thereto with respect to state information of a user and terminal, and establish a session using session establishment information defining the video event. The first terminal then transmits a data packet including the video event index, and the second terminal receives the data packet and outputs an image mapped to the video event index of the images stored in advance. Thus, by transmitting and receiving a predefined index alone without transmitting user and terminal states as a real time data-type image, the VoIP video communication method and apparatus prevent unnecessary waste of bandwidth in video communication.

Abstract: An apparatus and a method for automatically transmitting an emoticon during video communication in a mobile communication terminal are provided. In operation, location information is received during video communication, and data corresponding to the received location information is searched for from a memory. Image data captured by a camera and the searched data are synthesized and transmitted to a counterpart terminal.

Abstract: Disclosed is a method of fabricating a thin film solar cell. A separation process (‘P4’ process) of insulating a thin film solar cell from the outside is integrally performed with a transparent electrode patterning process (‘P1’ process) and a metallic electrode patterning process (‘P3’ process). This may reduce the fabrication costs and enhance spatial efficiency as the ‘P4’ process and equipment for the ‘P4’ process are not required.

Abstract: A method for coating a polyimide layer includes, placing a substrate on a print table; jetting polyimide liquid onto the substrate from a jetting surface provided over the print table; and wiping the jetting surface by moving a wiper from one side of the jetting surface to another side of the jetting surface while the wiper contacts the jetting surface, wherein the wiper is made of one of a perfluoro-based polymer.
