Abstract
A method of issuing a wireless tag includes a step of printing visual information corresponding to at least part of predetermined information to be stored in a nonvolatile memory of the tag on an image recording area of the tag, a step of writing the predetermined information into the memory by transmitting the information to the wireless tag by radio, and a step of reading the information written into the memory therefrom by radio and checking the read information with the predetermined information before writing. The number of checks made on a wireless tag is counted. A wireless tag for which the number of checks made reaches a predetermined number is recalled as defective.
