很好的,装置中阅读器、应答器均具有无线传输功能，频率和调制方式自由选定。不得使用现有射频识别卡或用于识别的专用芯片。装置中的耦合线圈为圆形空芯线圈，用直径不大于1mm的漆包线或有绝缘外皮的导线密绕10圈制成。线圈直径为6.6±0.5 cm（可用直径6.6 cm左右的易拉罐作为骨架，绕好取下，用绝缘胶带固定即可）。线圈间的介质为空气。两个耦合线圈最接近部分的间距定义为D。
阅读器、应答器不得使用其他耦合方式
-Very good device readers, transponders have a wireless transmission function, frequency and modulation freely chosen. Not allowed to use the existing radio frequency identification cards or used to identify a dedicated chip. Coil coupling device for hollow circular coil with a diameter of not more than 1mm of wire or wire insulation jacket 10 around the circle made of Micronesia. Coil diameter of 6.6 ± 0.5 cm (about 6.6 cm in diameter can be used the cans as the skeleton around the well off, can be fixed with insulating tape). Medium between the coil for air. The nearest part of the two coupled coils is defined as the distance D. Readers, transponder coupling should not be used in other ways
