How are you starting your preparations for your trip to Korea?
There is a prepaid card called "CHECK iN SEOUL" that is currently the talk of the town among travelers visiting Korea.
In this article, we will provide a thorough explanation of the benefits of this card issued by Lotte Card, why you should get it issued at the Lotte Mart Seoul Station branch, and the unmissable top-up perks.
1. What is CHECK iN SEOUL?
It is an all-in-one prepaid card exclusively for foreign tourists that combines "payment, transportation, and discounts" into one. With just this card, you can enjoy everything from buying souvenirs to riding the subway in a smart, cashless way.
2. Things to know before you use it! Pros and Cons
Pros
Powerful benefits at Lotte affiliates: You can receive discounts and reward points at Lotte Mart, duty-free shops, Lotte World, and more.
Top-up limit up to 2 million won: The limit is higher than WOWPASS and others, making it convenient for bulk purchases of expensive duty-free items and cosmetics.
Save on exchange fees: By utilizing local top-ups, you can reduce unnecessary overseas transaction fees compared to using your Japanese card every time.
Manage everything via the app: You can freely transfer and refund balances between your payment balance and transportation balance (eZL) within the app.
Cons
Transportation standard: Because it uses the "eZL" standard, it is not compatible with some minor T-money exclusive services (regular transportation use is fine).
Kiosk locations: While they are available at major spots, they are not everywhere in the city, so checking the app in advance is recommended.
3. [Pro Tip] Get it issued at Seoul Station to target "Top-up Benefits"!
