求翻译：Radio Frequency IDentification,，是一种通信技术，可通过无线电讯号识别特定目标并读写相关数据，而无需识别系统与特定目标之间建立机械或光学接触。是什么意思？

Radio Frequency IDentification,, is a communications technology, can identify a specific target by radio signals and to read and write data without having to identify specific goals established between the system and the mechanical or optical contact.

Radio Frequency IDentification, and is a communications technology that can identify specific goals through radio signals and read and write data without identification system with specific objectives established between mechanical or optical contacts.

Radio Frequency IDentification, is one kind of communication, may through the radio signals recognition specific goal and the read-write correlation data, but does not need to distinguish systematic and between the specific goal establishes the machinery or optics contact.
