摘要:
Content playback systems and methods, in which a desired content file can be easily played back in real time using radio frequency identification, are provided. The content playback system includes one or more tags, a playback unit, and a reader. The tags store one or more content files. The playback unit plays back a selected content file. The reader reads the selected content file, which is stored in one of the tags, in a non-contact manner and transmits the read content file to the playback unit.
摘要:
A wireless terminal and a radio frequency identification system for providing additional information and a method of providing additional information using the wireless terminal and the radio frequency identification system. The wireless terminal includes: a tag reader reading tag data from a radio frequency identification tag; a controller generating an additional information request signal with respect to the read tag data; and a communication network interface transmitting the additional information request signal through a communication network and receiving additional information with respect to the additional information request signal. Since the controller of the wireless terminal controls the radio frequency identification reader by optimally setting the information required for determining the time point for the radio frequency identification reader tag to respond, and utilizing the stored address of the additional information providing server, the additional information can be efficiently provided.

A radio frequency identification (RFID) tag and a RFID reader for anti-collision, and an operation method thereof are provided. The RFID tag includes a tag receiving part for receiving a tag recognition signal from a RFID reader, a tag transmitting part for transmitting a response signal and a tag data in response to the tag recognition signal, a mode switching part for switching current mode into a predetermined mode, and a controlling part for causing the predetermined mode to be switched by the mode switching part, when the response signal is transmitted by a predetermined number of times by the tag transmitting part. Accordingly, when a few number of RFID tags are used, collision of tag data can be prevented at the RFID reader, and the RFID tags are rapidly recognized.
摘要:
A method and apparatus for reducing the number of manipulations by a user during the data communication between an information device and a mobile device. The communication is performed with a data communication system that includes a mobile device; a display for displaying a position of the mobile device sensed using a provided position sensor and transferring data corresponding to the displayed position to the mobile device or data stored in the mobile device to the displayed position; and an information device for transceiving data with the display.
摘要:
A system for protecting signal emitting tag related information and a method thereof are provided. The method of protecting the signal emitting tag related information includes operations of receiving a request for the signal emitting tag related information, which is information related to a the signal emitting tag, and providing the requested signal emitting tag related information after authenticating the request. Therefore, a non-permitted user can be prevented from reading the signal emitting tag related information so that the signal emitting tag related information can be protected.
摘要:
A portable device includes an RFID reader for detecting a tag information of an RFID tag, a memory for storing the tag information detected by the RFID reader, and a controller. When a read command for the RFID tag is input and the tag information is valid, the controller controls the RFID reader to retrieve the tag information of the memory. If the tag information is invalid, the controller controls the RFID reader to re-read the RFID tag. The controller can determine whether the tag information is valid using the time and location. Because unnecessary operation can be omitted to read tags, power consumption is reduced and tag information check time is shortened.
摘要:
A mobile radio frequency identification (RFID) reader, a portable terminal having the same, and an RF transmission (Tx) power setting method thereof. The RF Tx power setting method includes selecting an RF Tx power of an RF Tx power which is used to read tag information from an RF identification (RFID) tag; and setting the selected RF Tx power to a Tx power of the RF Tx signal. Accordingly, since it is possible to variably set the Tx power of the RF Tx signal used to read out the tag information from the RFID tag, the power consumption can be reduced at the RFID reader or the portable terminal equipped with the RFID reader.
摘要:
A radio frequency identification (RFID) reader for offering tag related information and a method thereof are provided. The RFID reader includes a communicator which receives a radio frequency (RF) signal from an RFID tag, a controller which calculates location information of the RFID tag on the basis of the RF signal, and a display information generator which processes the location information of the RFID tag to be displayed on a display. Accordingly, even when a plurality of RFID tags are located around the reader, a user can identify the RFID tags with the identifications (IDs) of the RFID tags read by the reader.
