What is the innovative use of QR codes in Tokyo

While it is common knowledge that QR codes originated in Japan, a lesser-known fact is their crucial role in ensuring safety on Tokyo's subway system. The expensive machinery required for synchronized opening of platform safety doors and train doors has hindered widespread implementation. However, the innovative use of QR codes on platform doors allows cameras to read them upon the arrival of a train, ensuring the simultaneous opening of both sets of doors. This simple and cost-effective solution enables the installation of safety doors at more stations, thus enhancing passenger safety and preventing accidents.
