1 概论1.1 介绍在开发集成电路卡标准的过程中,很明显地,针对必须要标准化的目的和方法,存在着众多不同的观点。这是很自然的。原因是IC卡目前相对讲比较新,而且很少有人具有开发IC卡应用方面的实际经验。如果单考虑IC卡的话,理论上讲其应用可能性是无限的。然而实际上存在一些约束限制了某些方法的使用。为IC提供标准化的通用卡命令使得它与采用专用卡命令的那些卡相比,价格更便宜,安全性更高,而且有更多的存储区适用于各种应用。
1 Introduction 1.1 Introduction In the development of IC card standards, it is clear that there are many different points of view for the purpose and method that must be standardized. This is very natural. The reason is that IC cards are relatively new at present, and few people have practical experience in developing IC card applications. If you consider the IC card alone, in theory, its application possibilities are unlimited. However, there are actually some constraints that limit the use of some methods. Offering standardized IC cards for ICs makes them cheaper and more secure than those cards that use dedicated card commands, and more memory areas are available for a variety of applications.
