Our technology automatically detects whether your customer is paying from an iOS device such as a Macbook or iPhone with Touch ID that is using Safari. The Apple Pay button is only shown as a payment method to shoppers paying from an Apple Pay enabled device. After they select Apple Pay as the payment method, the payment is completed with the Touch ID or Face ID, creating a seamless experience for the customer.
If your customers have questions about how to set up Apple Pay on an iPhone, Apple Watch, iPad, or Mac computer, you can share this Set up Apple Pay support article for more information.
