Abstract:
The present invention relates to an RFID (Radio Frequency Identification) structure changing color according to the temperature, a method for fabricating thereof; a stacked film for preventing forgery, a method for fabricating thereof; an RFID tag, an RFID system and a method for controlling thereof; an RFID cap, a method for manufacturing thereof, a method for manufacturing container with contents; an RFID can, a method for manufacturing thereof; a packaging material, a method for manufacturing thereof, and a method for packaging product using the same; and a certificate for chipless RFID and a method for authenticating the same.
Abstract:
Disclosed are a communication system and a control method thereof. The communication system comprises a terminal apparatus for converting regional information or position information into network connection information, and a communication apparatus for performing network communication by generating a data packet comprising the network connection information. In the communication system and the control method thereof, a number, a floor and a room of a building, a number of a shelf, a multilayer, and positions of goods are input, so that a network having no data collision is established, and thus a user conveniently use an office/home network service. An integral input system for network connection information is provided using regional or position information, so that communication is stably performed without using an additional manager.
Abstract:
Disclosed is an information providing system using a network. The information providing system comprises a tag for transmitting a tag identification code, a mobile communication terminal for receiving the tag identification code through a first network, generating map request data and transmitting the map request data together with the tag identification code, a first computer for transmitting the tag identification code and the map request data, which are received from the mobile communication terminal through a third network, through a second network, a third computer for providing map data through the second network, and a second computer for receiving the tag identification code and the map request data through the second network, receiving the map data from the third computer, and transmitting the map data to the first computer. The first computer transmits the map data to the mobile communication terminal through the third network.
Abstract:
Provided are an RF reader and an RF system. The RF reader includes: a plurality of antennas; a path selector for selecting a transmit or receive path of an RF signal; an RF processor for processing the RF signal received through the transmit or receive path of the path selector; and a controller for controlling the path selector selecting a path.
