유비페이UBpay is a free payment platform developed by Harex Infotech. It allows users to register credit/debit cards and bank accounts to pay for memberships and coupons with just one password. This platform is safe and straightforward, as it does not store any of the user's financial information. All card and bank information is directly managed by the financial institution, ensuring secure transactions. 유비페이UBpay is available on various strategic partner apps, including s-mobile (Busan Bank), Mobile Banking (Kookmin Bank), and more. The registered payment methods include major credit/debit cards and bank accounts from various financial institutions such as Shinhan Bank and KB Kookmin Bank. 유비페이UBpay offers online and offline payment options, QR/barcode payment, NFC touch/bluetooth payment, and order pickup/delivery services.

유비페이UBpay provides customers with a safe and convenient payment solution that is easy to use. It is a free service, although data fees may apply depending on the user's data plan. The payment limit is the same as the credit limit of the registered credit card, and bank accounts and debit cards require sufficient funds in the account to be used.
