There are several methods to solve the collision. The part A of the norm ISO 14443 is based on a principle well-adapted to wired-logic cards: cards should answer in .

Reader collision refers to signal interference between readers when the working ranges of two or more RFID readers overlap. This interference can affect each reader’s ability to receive and decode label signals, resulting in inaccurate data readings.

I will explain the basic concept of anti-collision here, and then point you to some information that goes into more depth. Readers can not talk to two tags simultaneously. Rather, they must isolate a single tag, communicate with it and then move to the next one.The neighbor friendly reader anti-collision (NFRA) protocol offers a round-by-round sequence of commands for the RFID reader network in a centralized manner. Subsequently, an improved NFRA protocol with adaptive interrogation capacity (NFRA-AIC) is developed.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.

Therefore, an efficient, stable anti-collision protocol is crucial for RFID systems. This research analysed the current research into RFID anti-collision protocols and summarised means for its improvement through the mechanism of implementation of different types anti-collision protocols. Fair Reader Collision Avoidance (FRCA) protocol is a centralized protocol based on the TDMA and FDMA methods, which FRCA1 presented to reduce the reader-to-reader collision and FRCA2 introduced to decrease reader-to-tag collision.Therefore, we describe novel protocols to reduce reader collision problems by RSSI signal. They are mixed protocols between CSMA and TDMA based between a stationary reader and a mobility reader. Simulation results show that the proposed protocols improve RFID system performances. In the neighbor friendly reader anti-collision (NFRA) protocol , the readers connect to a polling server by a wireless link at UHF 433 MHZ, but this frequency was designed for active RFID systems. Therefore, the readers working with the NFRA protocol need extra hardware to connect at UHF RFID 433 MHZ.

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. We investigated the scaling of system performance with number of terminals using a commercially available NFC reader that implements anti-collision protocols supported by current NFC.Reader collision refers to signal interference between readers when the working ranges of two or more RFID readers overlap.
