Every ticket that you buy has an additional 500 won (RM1.50) added to it. Upon arival at your destination, you can return the ticket in another machine to get your 500 won back.
We were looking for something like an Octopus or an Oyster card but the closest thing to that was only the T-money card, which was the furthest from those.
The T-money is quite useless if you're there for only a few days like us. You see, you need to pay 2500 won (non-refundable) for he card, & then, you need to add in money for the trips. The 2500 won is just for buying the card. You'd get about 10% off every trip that you make, but to get your money's worth, you'd probably need to travel like 25 times.
