由于第二代计费的极度不安全，以希之光为代表的一批网吧计费厂商开始新一轮的探索，这一次他们在电源与POWER线之间接入了读卡器，跟踪网吧计费系统，一旦网吧计费软件被删掉，读卡器上马上会得到反馈信息，自动切断电源，这样就避免了删掉软件、不插卡就能上网的漏洞。

The adaptor is a must for numerous computer peripherals. As an important computer exporter worldwide, the dc power supply industry is bloomy in Taiwan. In today's dc power supply market, the switch power supply has replaced the linear adaptor as main stream in the industry globally for its compact size. However, SPS has a serious problem of high frequency electromagnetic interference and causes harmonic feedback for the AC power source compared with linear adaptor. The energy consumption is also worse for SPS than linear adaptor.

摘要整流器是许多电脑周边设备不可或缺的电能，而台湾又是电脑及周边产品出口大宗国，因此电源供应器产业澎勃发展是必然的，其中轻薄短小及输出稳定之交换式电源供应器(Switch Power Supply：SPS)，已取代传统线性整流器的地位，成为外销主力并取得世界龙头地位，然SPS有严重的高频电磁干扰问题(150KHz~300MHz)，在交流电源侧产生的谐波含量，也较线性整流器来得严重，为一耗能产品。
