Claims

[Scope of utility model registration request]

A tag body is provided for each product to be protected, and each tag body has a built-in alarm section that detects when the external circuit connected to the input becomes non-conductive and sets the alarm state. , a first conducting means that detects that the tag body is detached from the protected item and becomes non-conductive; and a first conductive means that locks the tag body on a fixed side and becomes non-conductive when the locking is released. An anti-theft device constituted by a series circuit with a second conducting means.
