Claim Text:
1. A wireless tag initialization device comprising: a reader and writer configured to transmit a supply signal at a first power level sufficient to activate a first wireless tag which is within a predetermined distance from the reader and writer and insufficient to activate a second wireless tag that is more than the predetermined distance away from the reader and writer, transmit a first command at the first power level to change a flag value of the first wireless tag that has been activated by the supply signal from a first flag value to a second flag value, transmit a second command at the first power level to cause the first wireless tag with the second flag value to transition into a response state, increase a power level of the supply signal to a second power level higher than the first power level, transmit a third command while the supply signal is at the second power level to cause the first wireless tag that has transitioned into the response state to write an initial value therein, and decrease the power level of the supply signal to a third power level lower than the first power level to change the flag value of the first wireless tag to which the initial value has been written, from the second flag value to the first flag value.
