摘要:
The method includes: a reader begins to count the tags, and waits for feedback of the tags; the tags are split into two subsets if the tags feedback the collision, the tags of one of the subsets feedback, the tags of the other subset begin to feedback when the tags of one of the subsets complete the count; when the collision occurs in the course of feedback, then the split continues until all the tags are completed the count; the tags of many branches are at least once split simultaneously when the tags of the subsets are split.
