Zusammenfassung:Provided is a method for communication with between readers having dual sensitivity modes for avoiding conflict between readers arising from interference each other when simultaneously used in a limited space. The method for communication between a tag and a reader using dual sensitivity modes for avoiding conflict between the reader and the tag includes: initializing the reader to a normal sensitivity mode; temporarily selecting a frequency channel by the reader; checking whether or not a different reader uses the selected frequency channel; repeatedly selecting another frequency channel if the other readers occupy the selected frequency channel; switching to a reduced sensitivity mode if the other readers do not occupy the selected frequency channel; and communicating with the tag by the reader in the reduced sensitivity mode.
