Variety and details
Thread (center thread and side thread)
Starting in 1974, the Reserve Bank added a metallic security thread down the centre of banknotes as a new security feature. Because the center position is also the place where people fold their banknotes, they used prematurely. This is why the Reserve Bank moved the position of the thread to the side. The location of the thread (a dark line) can easily be found by looking at the banknote with enough lights passing through it.
