If you have a Squarespace site that you're using to sell your wares, your online store can now accept Apple Pay via the iPhone and the upcoming macOS Sierra. Now visitors can buy stuff without digging out their credit card.
To make sure your site accepts Apple Pay, Squarespace notes that you should make sure your site accepts Stripe payments and enable the new online checkout experience in settings.
Shopify is also allowing its customers to add Apple Pay to their retail sites. The move by both companies not only reduces payment friction from Apple devices, it also adds an additional level of security since each transaction has its own unique token.
