永远不要接受来自不安全网站的代码来处理与真钱有关.
您不知道是谁在给您代码，您不知道它是做什么的，您也不知道它是在没有将详细信息传递给任何第三方的情况下将款项正确地放入适当的帐户中的.

仅从信誉良好的卡交易服务公司获得此类代码-否则欺诈的范围就很大.并且请记住，如果您的行为似乎疏忽，您个人可能会承担任何损失的责任-从公共论坛获取代码绝对是可以的！

Never, ever, accept code from a insecure website to handle anything to do with real money.
You do not know who is giving you the code, you do not know what it does, you do not know that it places the monies correctly into the appropriate account, without passing the details to any third parties.

Only get such code from reputable card transaction service companies - the scope for fraud otherwise is far to large. And remember, you personally could be liable for any monies lost if your action seem to be negligent - which getting your code from a public forum would most certainly be!
