Abstract
As a contactless identification tag is removed from a commercial product, a section to be detected is cut and separated from a removal detection circuit section composing the contactless identification tag and remains on the commercial product. When a detection section judges that the section to be detected is removed from the contactless identification tag, the contactless identification tag changes functions.
