    • When a user who has a magnetic substance attached paper enters a gate which generates a magnetic field, steep magnetization reversal is produced in the magnetic substance by the magnetic field. As a result, pulse current flows into a detection coil provided in the gate, and a generated waveform signal indicating a characteristic transient response is output to a terminal device. The terminal device calculates correlation coefficients of this waveform and a plurality of stored reference waveforms, additionally calculates an average of the calculated correlation coefficients, and determines whether or not the average is equal to or more than a threshold. When the average is equal to or more than the threshold, the terminal device instructs an imaging device to image a user. When the average is below the threshold, the imaging device is not allowed to image the user.
    • 当具有磁性物质的纸张的用户进入产生磁场的门时,通过磁场在磁性物质中产生陡峭的磁化反转。 结果,脉冲电流流入设置在栅极中的检测线圈,并且向终端装置输出表示特征瞬态响应的生成波形信号。 终端设备计算该波形和多个存储的参考波形的相关系数,另外计算所计算的相关系数的平均值,并确定平均值是否等于或大于阈值。 当平均值等于或大于阈值时,终端设备指示成像设备对用户进行成像。 当平均值低于阈值时,不允许成像设备对用户进行成像。
