What Most Travelers Get Wrong
Many visitors assume there’s just one standard transport card in Korea.
In reality, there are three different systems:
- T-money → Pay per ride
- Climate Card → Unlimited rides in Seoul
- K-Pass → Discount/refund system for residents
Choosing the wrong one can mean paying more than necessary—or not being able to use it at all.
