Samsung Pay started with support for a subset of credit and debit cards when it launched almost two years ago. Over time, Samsung added new cards and banks to the service. Today, it’s adding something that isn’t a card—PayPal accounts. Plug in your account, and you can pay with PayPal anywhere Samsung Pay is accepted.
Importantly, this is not the same as getting a PayPal debit card and registering it with Samsung Pay.
