For a long time, it is a considerable, frequent and tiresome social activity to charge the consumers of public traffic service industry. It brings much incontinence for the consumers and this industry. The development and application of Information Card brings convenience for society existence. But, present Contact IC is lack of memory, security and duration. It is not suitable for the circumstance where the flow of bus-takers is. It's not easy to insert or take it out, and the read-and-write unit is weak. Radio Frequency Card is avoid above-mentioned shortcomings, so it has a bright future in the public traffic field and other service industries which inquire identification.

长期以来，公共交通服务行业的收费是一件最大量、最频繁、最琐碎的社会交往，给行业也给消费者带来诸多的问题，信息卡的开发应用给社会生活带来很多便利，目前，磁卡信息存储量少，保密性差，易损坏；IC卡在公交这样人员流动多，要求收费迅速且环境差的场合，这类卡的插入与取出就显得不方便，且读写器易损易脏，卡上的IC片也易损坏，射频卡克服了上述不足，因此在类似于公交系统这样的服务行业以及许多需要身份识别的场合，将有广阔的前景。
