Abstract
Systems and methods for operating a security tag. The methods comprise: transitioning a pin head from an extended position to a collapsed position by causing at least one first telescoping segment to slidingly engage a second telescoping segment; locking a shaft, extending out and away from the pin head in the collapsed position, using a securement mechanism disposed inside a housing of the security tag; and preventing a transfer of pin head rotation to the shaft at least when the shaft is locked by the securement mechanism.
