Abstract:
1. A wireless tag that includes a unique ID, comprising: a first encoded data generator that generates first encoded data of different values based on the unique ID for each time of receiving an ID inquiry; a second encoded data generator that generates second encoded data used for decoding the first encoded data, the second encoded data having a different value corresponding to the first encoded data of different values; a communication unit that replies to the ID inquiry for each time of receiving by transmitting a combination of the first encoded data and the second encoded data; and a flag that, in reply to each ID inquiry, is set whether to reply with the unique ID or with a combination of the first encoded data and the second encoded data, wherein when the flag is set to reply with the unique ID, the communication unit replies to each ID inquiry by transmitting the unique ID instead of a combination of the first encoded data and the second encoded data.
