Samsung claims that its system will work with almost all point-of-sale systems: NFC, magnetic stripe and EMV (Europay, MasterCard and Visa) terminals for chip-based cards.
It won't work with readers where you need to physically insert your card into a slot, however, such as those found at gas stations and on ATMs.
Using Samsung Pay in stores around San Francisco, I found that it was accepted almost everywhere. These included vendors using Square readers; NFC terminals in major chain retailers like Trader Joe's and Walgreens; and magnetic stripe readers in smaller stores. Merchants may still require you to sign a receipt for the transaction.
