Because of the internet, we can read books and newspapers without going to the bookstore and library (if you want to maintain a status of literate). Besides, we can do shopping without going to the market place, can meet friends, see prospective partners, and get married without going to see the real person (chatting on QQ, loving on line, having factious marriage on internet), and so on. Finally, we do not only care for meeting each other, we also don't care for calling or even sending short messages to others. Our life then lost the so called "communication function" or "communication necessity" by the functional linguisticians.

因为网络，读书看报不用去书店或图书馆了（假如还有几个人想维持识文断字的身份的话），购物不用去商场了，找朋友、相亲、结婚也不用真的与人见面了（QQ聊天、网恋、网络虚拟婚姻），等等，最后，人与人之间，不仅不愿见面，连电话也不打了，甚至短信也懒得发了，生存已经失去了功能语言学所说的"人际功能"或人际必要了。

Based on the hypothesis of Brands, this thesis presents two off-line electronic cash system applied to small payment: one is an off-line nondivisible electronic cash system with complete anonymity, and the other is an off-line nondivisible electronic cashsystem with repealed anonymity. The two systems can solve the bottleneck problem of bank server. Furthermore, based on the concept of virtual debit as well as the payment demand of pay-per-use electronic commerce and mobile commerce, this paper designs a micro-system NPAY, which can solve the problem of extra-consuming, greatly reduce the system communication overhead, and the consumer can anonymously consume.

基于Brands假设，设计了两个适用于小额支付的离线电子现金系统：一个是具有完全匿名性的离线不可分电子现金系统，另一个是可撤消匿名性的离线不可分电子现金系统，这两个系统都较好地解决了银行服务器的瓶颈问题；针对即付即用(pay-per-use)类型电子商务和移动商务的支付需求，基于&虚借记&的概念，设计了一个微支付系统NPAY，较好地解决了消费者超额消费问题，系统的通讯开销也大大减少，并且消费者可以匿名消费。
