RFID label collision occurs when multiple tags send out signals at the same time, causing these signals to overlap or conflict in the air, making it impossible for the reader to distinguish and decode the data from each label. To avoid this problem, the EPC Gen 2 air-interface protocol standard employs a unique anti-collision protocol based on a tag’s ability to generate random numbers. The anti .

ISO15693-3 Anti-Collision • Explanation of an anti-collision sequence: • The following text and figure summarizes the main cases that can occur during a typical anti-collision sequence .During the anti-collision phase, three or four different frames are received from a tag (ATQA, UID, SAK and optional ATS). The ATQA, SAK and ATS values can be used to identify the .Tag collision is the event that the interrogator (reader) cannot identify the data of tag when more than one tag occupies the same communication channel simultaneously. The reason is that .RFID label collision occurs when multiple tags send out signals at the same time, causing these signals to overlap or conflict in the air, making it impossible for the reader to distinguish and decode the data from each label.
To avoid this problem, the EPC Gen 2 air-interface protocol standard employs a unique anti-collision protocol based on a tag’s ability to generate random numbers. The anti-collision technique used, known as the “Q Algorithm,” is explained in non-technical terms in our article Part 1: Understanding the EPC Gen 2 Protocol.What is anti-collision ? Most of the RFID systems, including contactless cards at 13.56MHz and NFC, are based on the RTF principle, Reader Talk First. When it is looking for a card, the reader sends periodically research frames and every card receiving a research frame answers by transmitting its ID.
RFID solutions should use an anti-collision methodology to reduce tag collisions. What causes RFID tag collisions? When multiple tags transmit to a reader simultaneously, their diffracted signals deactivate each other, leaving the reader with an indecipherable message.To minimize tag collisions, RFID readers must use an anti-collision protocol. Different types of anti-collision protocols have been proposed in the literature in order to solve this problem. This paper provides an update including some of the most relevant anti-collision protocols.This NFC Interface and Protocol (NFCIP-1) standard allows, but does not specify, applications in network products and consumer equipment. Compared to the 2nd edition of Standard ECMA-340 (published in December 2004), this 3rd edition: - corrects editorial mistakes; - enables the use of NFC-SEC (ECMA-385); and In the RFID systems, data collision is inevitable when the reader sends a communication request and multiple tags respond with simultaneous data transmission. Data collision is prone to causing problems such as: identification delay, spectrum resource waste, a decreased system throughput rate, etc.
ISO15693-3 Anti-Collision • Explanation of an anti-collision sequence: • The following text and figure summarizes the main cases that can occur during a typical anti-collision sequence where the number of slots is 16. The different steps are: a) The VCD sends an inventory request, in a frame, terminated by an EOF. The number of slots is 16.During the anti-collision phase, three or four different frames are received from a tag (ATQA, UID, SAK and optional ATS). The ATQA, SAK and ATS values can be used to identify the manufacturer, tag type and application.
Tag collision is the event that the interrogator (reader) cannot identify the data of tag when more than one tag occupies the same communication channel simultaneously. The reason is that whenever two or more users are transmitting on the shared channel simultaneously, a collision occurs and the data cannot be received correctly.
