摘要
本文对非接触式识别卡的国际标准（ＩＳＯ１４４４３）草案中互不兼容的两种通信方案进行了比较分析。在功率传输，频带占用，信号通信接口和防碰撞协议几方面对比两种方案的优劣，给出了量化结果。
Issues associated with two incompatible schemes-TYPE A and TYPE B of proximity contactless identification card standard ISO 14443 are discussed. Topics as power transfef, spectrum collocation, signal communications, initialization and anti-collision, performance of the two types are analyzed and compared. The results presented in this paper show the advantages and disadvantages of both schemes and are used to propose directions for future research and development.
