The Radio Frequency IDentification (RFID) system is a new emerging technology used to identify a tag attached to an object. To make RFID systems practical, the cost of RFID tags is very important. Further, an interrogator should be able to identify the number of tags in the reading range in a short time. The most important technical issue in RFID is to correctly and quickly recognize the number of tag IDs in the reader's communication range. Unlike the probabilistic RFID tag identification schemes, a Query Tree (QT)-based protocol guarantees the identification of all the tags, where the distribution of tag IDs is assumed to be uniform.
