摘要： A reader/writer (RW) requires identification of anti-collision techniques used by IC cards (A, B, C, and D). The IC cards implement answers to the anti-collision technique identification requirement by the reader/writer at different timings respectively for respective IC cards among the IC cards which use different anti-collision techniques respectively. The reader/writer requires identifications of types of the IC cards in dependence upon the anti-collision techniques in response to the answers by the IC cards. The IC cards return identification data thereof in response to the card type identification requirements by the reader/writer for respective IC cards among the IC cards which use different anti-collision techniques respectively. The reader/writer identifies the types of the IC cards in response to the identification data of the respective IC cards.

摘要翻译： 读写器（RW）需要识别IC卡（A，B，C和D）使用的防碰撞技术。 IC卡分别针对使用不同的防碰撞技术的IC卡中的IC卡分别在读取器/写入器的不同时刻分别解决反冲突技术识别要求。 根据IC卡的答案，读/写器需要根据防碰撞技术来识别IC卡的类型。 IC卡分别根据使用不同防碰撞技术的IC卡中各IC卡的读卡器的卡类型识别要求，返回其识别数据。 读/写器根据各IC卡的识别数据识别IC卡的类型。
