QR codes to aid barrier door operation on train platforms

In a world-first, QR codes are being used in the operation of platform safety barriers at train stations — a development aimed at accelerating the installation of barriers and slashing the hefty cost. The new system also has the advantage of being able to handle trains with different door placements. Safety barriers to prevent people from falling onto the tracks are being installed on station platforms ahead of the 2020 Tokyo Olympics and Paralympics. The Tokyo metropolitan government launched a practical demonstration of the new system on the municipal Toei Subway lines last month.
