<p><P>PROBLEM TO BE SOLVED: To exclude the repetition of a response to a communication terminal, which completes reading, as much as possible, and to suppress processing delay due to that a contactless communication medium is set to a non-response state in a communication system for reading the contactless communication medium by the communication terminal. <P>SOLUTION: A contactless communication system 1 includes: an RFID tag 20 using a plurality of identification flags; and a communication terminal 10 for performing contactless communication with the RFID tag 20. The communication terminal 10 is configured to transmit a designation command to designate the type of an identification flag to an RFID tag 20. Furthermore, the communication terminal 10 is configured to determine whether a non-response state from the RFID tag 20 continues in a prescribed time or more, and to, when determining that the non-response state continues in a prescribed time or more, change the designation of the identification flag to the identification flag whose type is different from the type designated in the non-response state which has continued. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
