Starting tomorrow, something interesting is appearing on the Busan subway because of the BTS concert.

I hope this is helpful for those going to the Busan concert this time.
They say that starting tomorrow, you can buy tickets directly at the subway station using a QR code.
I think it will be convenient since you can pay with a credit card or mobile app without installing an app.
It would be really great to take foreign friends there as well.
Let's all comfortably pass through the station and meet at the venue.
