If you have an iPhone, you have Apple Pay. Android users, meanwhile, have Android Pay. Both are excellent platforms designed to make payments more convenient and more secure. But they’re small time compared to Samsung Pay, which just launched in the U.S. this week. It’s too bad not everyone can use this great new service, because it’s easily the best on the market.

What sets Samsung Pay apart is that it works with old magnetic stripe technology, which means you’re not just confined to places with NFC terminals. That means you can use your Galaxy S6 Edge to pay for some food at the mom and pop place down the street—something you can’t do with Apple Pay or Android Pay (unless it has an NFC terminal).

There are a few caveats with Samsung Pay right out of the gate. Right now you need a Visa, MasterCard, or America Express card issued from Bank of America, Citi, American Express, or U.S. Bank. Apple Pay is backed by well over 500 banks, so the disparity of support is quite large. Hopefully Samsung Pay can get many others onboard as the platform matures.

You also can’t use Samsung Pay at terminals where you actually have to dip your card in. So subways, gas stations, ATMs and other similar places probably won’t be on board the mobile wallet revolution—at least not for a while. Still, Samsung’s service can be used at way more places than Apple Pay and Android Pay, and it doesn’t matter if it’s a magnetic-based terminal or one with NFC.

Not everywhere lets you swipe your card—restaurants are a prime example—so the digital wallet is still on hold in a lot of ways. But as it gains support by more banks, Samsung’s platform will be the clear leader as more and more payments are done with a phone. Unfortunately, you’ll need a 2015 Galaxy phone (Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge Plus, Galaxy Note 5, though at the time of this writing Verizon branded devices are excluded) to take advantage of Samsung Pay.

If you do have one of those devices, prepare to start paying with your phone at a lot of places. Check out the video to see what it’s like to use Samsung Pay, and some thoughts on how it works out in the real world.
