Wireless Industry changing life in every segment
A new campaign has begun to remind South Korean commuters to give their seats to pregnant women. Called the Pink Light Campaign, it distributes signal chips to pregnant women to carry around. When the signal chip enters a train car, it activates a dedicated pink light by the dedicated pregnant courtesy seat, alerting the person sitting there that a pregnant woman has entered the train and is standing. The light remains on until the woman has found a seat.
