This is an EZL card, a transportation card for use on the South Korean subway and public transportation (renamed from Cashbee). It functions as a transportation card similar to the Tmoney card, and because it has an IC chip, it can be used anywhere that accepts credit cards. It's also recommended for those who are uneasy about using credit cards overseas. You can top up the card at subway ticket machines and convenience stores in South Korea. If you download the EZL card app, you can also top up from your credit card. While the wowpass requires separate top-ups for Tmoney and wowpass, making balance management complicated, the EZL card allows you to pay transportation fees within the same balance, making it the most convenient card, in my opinion. I used it only once during a trip in December 2025. The remaining balance is 50 won. It's in very good condition! *The Dongdaemun Super Pass booklet in the image is not included.
