Samsung Pay is Samsung’s mobile payment system, a digital wallet platform for contactless payments which works in almost all stores — including those that use older magnetic stripe point-of-sale terminals — without merchants needing to opt-in to any program or update hardware.
Samsung Pay only works with four Samsung phones: the Galaxy S6 Edge+, Galaxy Note 5, Galaxy S6 and S6 Edge. It will also be available on the Gear S2 smartwatch when it is released, but only for transactions on NFC terminals.
The phone also needs to be on one of the following carriers in the United States: AT&T, Sprint, T-Mobile, US Cellular or Verizon.
You will need a Visa or MasterCard issued by Bank of America, Chase, Citibank or US Bank. American Express is also supported.
