Samsung Pay is a mobile wallet that runs on top of existing card networks like Visa, Mastercard, and American Express. Rather than replacing card infrastructure, it wraps it in an additional security layer: card details are tokenized, and every transaction requires fingerprint or PIN authentication backed by a hardware Secure Element chip in the device.

For merchants, the practical implication is simple: pricing follows the underlying card, not a separate wallet fee. If a customer pays with a tokenized Visa through Samsung Pay, you pay Visa rates.

It works online and in-person across a broad footprint, mostly Singapore, Australia, Hong Kong, the US, UK, Germany, France, Brazil, and more. In-person acceptance covers both NFC terminals and MST (magnetic stripe transmission), which extends compatibility to older hardware that doesn't support contactless.

Samsung Pay also stores loyalty cards, which matters for retail merchants building repeat purchase behavior. Settlement timing depends on the acquirer rather than a fixed delay.

If you're already accepting cards, enabling Samsung Pay adds no new pricing complexity and extends your reach to Samsung's device base with stronger transaction security than a standard card swipe.
