Samsung Pay is rolling out to Malaysia, Russia, and Thailand, bringing the mobile wallet to 10 countries by the end of this year.
Since its debut in Korea last summer, the digital wallet has expanded to the US, China, Australia, and Singapore, among others.
"When we introduced online payments in South Korea last year, the service was well received by the market," Thomas Ko, vice president and global GM for Samsung Pay, said in a statement.
Online payments accounted for more than a quarter of the company's 2015 transactions, "demonstrating that consumers may be actively looking for solutions to make their online experiences faster, simpler, and [more] secure," Ko added.
Samsung has also partnered with MasterCard to offer a "simplified online payment and express checkout solution" through Masterpass in the US.
Available for in-app payments and online retailers, Masterpass over the summer expanded to physical stores, where customers can use smartphones to pay at the register—just as they would with offerings from Apple, Google, or Samsung.
Samsung now provides online payment functions like express checkout, which allows folks to use their Mastercard credit or debit card, along with the shipping details saved in their Samsung Pay account, to complete transactions on a computer, tablet, or mobile phone. The service employs an encrypted token instead of card numbers, and allows the user to authenticate payments via the fingerprint scanner built into Samsung devices.
"By partnering with Masterpass in the US and rolling out online payments globally, we will simplify the online transaction experience by eliminating the need for customers to fill out tedious online checkout forms, remember long passwords or fumble for their wallets," Ko said.
Samsung also introduced new features in the US, including support for in-app payments and new nearby discounts and savings.
