Samsung Pay won’t actually launch until later this summer, but the mobile payment service is already up and running in one country. The company recently kicked off a trial run for the Apple Pay competitor in Korea.

Samsung Pay is limited to a select group of people using the Galaxy S6 or Galaxy S6 Edge for now. The service is also expected to work with the upcoming Galaxy Note 5, Galaxy S6 Edge Plus and the rumored Gear A smartwatch. Samsung previously said it plans to launch the mobile payments app in the U.S. and South Korea in September before expanding in Europe and China.

Samsung also offers a few new details on how its payments service will work. Once you download the app, you’ll watch an introduction video and log in using either a PIN code or your fingerprint. After that you can add credit and debit cards using your phone’s camera or manually if you prefer.

You’ll simply swipe up to launch the app. This gesture apparently works from the home screen, lock screen, or even when the screen is off. Then just hold your device up to the register and pay using your fingerprint or PIN. You can also check your payment history by tapping on a specific card.

Samsung Pay sounds pretty cool, and the option to pay at most magnetic strip scanners thanks to built-in magnetic secure transmission (MST) technology from LoopPay means the app will work at a lot more locations than Apple Pay right off the bat. We can’t wait to try it out for ourselves once it finally launches in America.
