What is Apple Pay?
Apple Pay allows you to make purchases directly from your supported Apple device, including iPhone™, Apple Watch™, iPad™ or Mac™.
In store: Just hold your iPhone near the reader with your finger on Touch ID™, or double-click the side button on your iPhone or Apple Watch to use Face ID™, then hold it near the reader. The transaction in store occurs within seconds.
On the web: Using the Safari web browser, just use Face ID or Touch ID to complete your secure transaction.
Within apps: While using apps on your iPhone or Apple Watch, checking out is as simple as placing your finger on Touch ID, or using Face ID.
