A wireless identification tag for embedding into an electrically conductive surface of a rotatable work tool, the tag comprising at least a first and a second inductive planar loop having corresponding first and second terminals, wherein the first inductive planar loop and the second inductive planar loop are arranged in relation to a common plane and wherein the first inductive planar loop and the second inductive planar loop are arranged to cover separate areas of the common plane, where each area on the common plane is associated with a respective polarity of the magnetic flux normal to said plane.

It is provided a protection device for being provided inside a key fob to selectively inactivate the key fob. The protection device comprises: a first conductive layer; a second conductive layer; an insulator layer between the first conductive layer and the second conductive layer, the insulator layer preventing conductive contact between the first conductive layer and the second conductive layer; and a switch conductively coupled between the first conductive layer and the second conductive layer, the switch being wirelessly controllable to be in a conductive state or a blocking state.
