Upass is a special card that helps people travel around South Korea using public transportation like buses, subways, and trains. It's like a magic card because you can just tap it on a machine and it pays for your ride automatically. No need to carry coins or paper tickets!
When you get an Upass, you have to put some money on there first. This is called 'loading'. Every time you use Upass to travel, the money is taken out automatically. But don't worry, you can always add more money to it later if you run out.
Upass is really helpful because it's cheaper than buying a single ticket every time you travel. Plus, you can use it on multiple types of transportation, so you don't have to worry about buying separate tickets for each one.
To get an Upass, you usually have to go to a place called a 'transportation card center' or a convenience store. You may have to show some identification or fill out a form, and then you can get your very own Upass card!
So, Upass is basically a card that helps you travel around South Korea easily and saves you money. It's the perfect companion for people who love to explore the city using public transportation.
