A robust tag. The robust tag may include a body section, at least one movable latching member disposed within the body section, at least one attachment structure receivable within the body and selectively engageable to the at least one latching member; and at least one responsive member disposed within the body and in cooperative arrangement with the at least one latching member. Upon the application of a signal to at least one drive position on the body section, the responsive member generates a flexural wave that induces a movement of the at least one latching member, so as to disengage the at least one latching member from the at least one attachment structure.
