Samsung Pay works almost anywhere you can swipe or tap your card. From the grocery store to the coffee shop to your favorite clothing stores, Samsung Pay is the only mobile payment service that works at the majority of U.S. retail locations. In situations where you have to dip your card or in places where you don’t swipe your card yourself (e.g. sit-down restaurants, hotels, auto shops.), it’s better to use your actual card. Samsung Pay doesn’t currently work at gas station pumps with dip readers, but it will work at most gas station cashier card readers.
