Patent ID: 7538677

Claim:
A contactless identification tag for attaching to an object, the contactless identification tag comprising: a driving electric power generation part; a first data reception part; a first data transmission part; a detachment detection part including a first detective resistor part and second detective resistor part that is electrically coupled to the first detective resistor part; a control part including a voltage monitoring part that is electrically connected to a joint part through which the first detective resistor part is electrically coupled to the second detective resistor part; and an adhesion part including a first adhesion part and a second adhesion part, the second adhesion part being separable from the first adhesion part, the first detective resistor part being formed on the second adhesion part, and a wiring of the first detective resistor part being contacted to a wiring included in the detachment detection part with a combining force strength that is weaker than a strength of an adhesive force with which the first adhesion part is attached to the object.
