The review of modern technologies of construction of radio-frequency identification (RFID) systems, which are an integral part of the Internet of things, is presented. The advantages and disadvantages of radio-frequency identification compared to the other methods of identification of smart things are described. The classification of radio-frequency labels by the most essential for RFID systems features is given. The purpose of anti-collision algorithms in radio-frequency identification systems is considered. The classification of anti-collision algorithms that may be used for the organization of interaction of radio-frequency labels with the reader in different-purpose RFID systems is presented. The possibilities of random, deterministic, spatial and correlation algorithms of anti-collision are described and analyzed. A correlation approach to the elimination (avoidance) of collisions in relation to RFID tags on surface acoustic waves is developed.
