Apple Pay support in Safari will eliminate the need to directly enter and store credit card and payment information in the browser when making online purchases. It will also eliminate the need for customers to download a store's app to make a payment with Apple Pay. At WWDC 2016 in June, Apple said that many merchants have already agreed to support the mobile payments service on the web at launch.
Apple Pay is currently available in the United States, United Kingdom, Canada, Australia, China, Switzerland, Hong Kong, France, and Singapore, and Apple lists web support as "coming this fall" in all of those regions except the U.K. on its website. Earlier this year, Apple Pay vice president Jennifer Bailey said Apple is "working rapidly" to expand the service to additional countries in Asia and Europe.
