| 1. A tag conflict avoidance system, comprising:
a plurality of tags receiving a first signal, converting identification codes of the tags into predetermined codes according
to the first signal, and outputting the converted codes as second signals; and
a reader outputting the first signal, receiving the second signals, and identifying the tags using the codes included in the
second signals;
wherein the codes are converted by reading n-bits of the identification code and converting the n-bits of the identification
code into a K-bit code (K>n) including only one bit value “1”.
