<P>PROBLEM TO BE SOLVED: To efficiently measure the resonance frequency of a contactless IC card and confirm communication operation by a single apparatus continuously. <P>SOLUTION: In the contactless IC card measurement apparatus, a signal of a prescribed frequency is input to a measuring coil 303 and a return signal from the measuring coil 303 is measured, so that the resonance frequency of the contactless IC card is measured by a network analyzer 301. Further, a signal for confirming communication operation is input to the measuring coil 303 and a receiving signal wirelessly received from the measuring coil 303 through a probing coil 313 is measured, so that the communication operation of the contactless IC card is confirmed by an oscilloscope 314. The resonance frequency measurement and communication operation confirmation are switched by a switch 302 so as to be continued as a series of processing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
