What is a payment gateway (PG)?

First, what is a payment gateway? From Wikipedia:

“A payment gateway is a service that authorizes credit card or direct payments processing for e-businesses, online retailers, bricks and clicks, or traditional brick and mortar. The payment gateway may be provided by a bank to its customers, but can be provided by a specialised financial service provider as a separate service, such as a payment service provider.”

How to choose which payment gateway suits you?

  • If (most of) your customers are in Korea, you will need a Korean payment gateway.
  • If your customers are international it is better to connect PayPal or alternative (Eximbay).

In order to complete this online store payment process, it is essential to connect the PG to proceed with purchases and payments. In addition, localization of payment methods is essential to meet the needs of customers in different countries if they want to enter not only domestic, but also overseas markets.

Korean payment gateways

In Korea, there are 3 Korean payment gateways that you can connect to Shopify:

  • KG Inicis
  • Eximbay
  • Payment Wall Korea

First, let’s take a quick look at the features of each PG as well as the fees. By looking at the characteristics of each company, you can find out which PG fits the personality of your online store.

Note: hereafter, when we write “fees”, they are all fees per transaction.


Eximbay is a Korean PG, a cross-border payment company that provides the most global payments in Korea. Sellers in Korea looking to expand their stores overseas can easily expand their global payment methods through Eximbay. In addition, overseas stores targeting Korean customers can also receive overseas settlement support by using the Eximbay global integrated payment service.

Eximbay is a simple payment service like a Korean credit card, Kakao Pay, Payco, Toss, etc., or international credit cards such as VISA, Master, JCB, AMEX, and Unionpay, PayPal, WeChat Pay (a payment service of WeChat, a Chinese messenger app). Eximbay supports Alipay, Bestpay, Japanese payment service Exontext and Russian payment service Yandex Money.

In addition, it provides services not only to global online stores, but also to various industries such as department stores, duty-free shops, hotels and convenience facilities both online and offline.

If you are a merchant targeting East Asia such as Korea, China, Japan or Russia, this is a PG that is worth considering. With the investment attraction recently, Eximbay can be expected to accelerate the expansion of cross-border payments and provide more stable services in the future.

KG Inicis is a representative online and offline PG in Korea that has the No. 1 market share in the Korean electronic payment payment market.

Almost all services are familiar to consumers in Korea:

However, this means that linking your Shopify store is limited to credit cards and debit cards that issued in Korea. Credit cards and debit cards issued overseas cannot be used. Overseas customers will not be able to buy from your store if you use KG Inicis.
