专家请看以下句子：
The casio issued to him, as a good customer, a Fun Card, which when used in the casino earns points for meals and drinks, and enables the casino to track the users gambling activities.
【我的疑问】请帮我剖析句子的结构。
另外，本句中的 issued to 怎么样理解？
which 后面如何可以接 when？
谢谢专家的指点！
The casio issued to him, as a good customer, a Fun Card, which when used in the casino earns points for meals and drinks, and enables the casino to track the users gambling activities.
【翻译】卡西欧公司作为优质顾客向他发放了一张“娱乐卡”，此卡在卡西欧赌场用时可以赚餐饮点数，并使赌场可以跟踪用户的赌博活动。
【剖析】issue 是及物动词“发放；发行”，及物动词是需要接宾语的。那样，其宾语是a Fun Card。我重新改写一下这个句子：
The casio issued a Fun Card to him as a good customer,...
因为a Fun Card后面跟了一个非限制性定语从句，所以把它置于状语后面，如此做是为了照应后面的定语从句，让定语从句紧挨着先行词。为了理解，我定语从句再改写一下：
which （= a Fun Card）earns points for meals and drinks, and enables the casino to track the users gambling activities when it is used in the casino.
