What is RFID tag collision?


RFID tag collision is a situation where multiple tags reflect signals back to the reader in the exact same time frame, causing data confusion and incorrect identification. Although there are different systems designed to tackle this problem, the most common system is to have the tags delay their response to the reader by a set time frame (milliseconds) so that the data can be read one at a time. Since the delay is very small, it will appear as though all tags are being read simultaneously.
