Apple announced that Apple pay will be available on Safari.

Mac users will be able to pay online through Safari using a “Pay with Apple Pay” button, and use their Touch ID via iPhone or watch for authentication. Once users are ready to check out, Apple’s Continuity feature will pull up a prompt on the iPhone or watch for authentication.

Retail partners will  need to integrate Apple Pay into their checkout, and Apple has stated that many merchants have signed up for the payment platform.
