Can I swipe my card in Jeju Island Central Underground Commercial Street?

Many shops and restaurants in Jeju Island can directly swipe UnionPay cards.

But some small shops can't do it.

The Central Underground Shopping Mall is an underground street in the northern city of Jeju. Many shops are private, so each one is different after entering.

Maybe some can, and some can't.

Where is the most cost-effective way to exchange won for a trip to Jeju Island?

Tourists are going to travel freely in Jeju Island. If possible, they can exchange a small amount of won in domestic banks in advance. (Carrying a lot of cash is not recommended)

Visitors who are inconvenient or have no time to exchange Korean won in China can choose to exchange Korean won in street shops in Jeju City after arriving in Jeju Island.

It is more cost-effective than Jeju Airport Bank.

UnionPay cards can be used directly in many consumer places in Jeju Island, and it is not recommended to exchange a large amount of won in China or Jeju Island.

Remarks: (Even if you run out of won, you can exchange it at the local money exchange shop in Jeju at any time)
