Shop Pay is an accelerated checkout that lets customers save their email address, credit card, and shipping and billing information. This can save your customers time when they check out, especially if they've already opted in to Shop Pay on any Shopify store. If your store offers a local pickup or delivery option, then customers can choose that option during checkout with Shop Pay.

A customer needs to enter an email address at checkout in order to save their payment information. Customers who only enter a phone number in the contact field aren't offered the Remember me prompt to save their information. Learn more about accelerated checkouts.

The customer’s shipping and billing information is securely stored on Shopify’s PCI compliant servers and is only shared with your store if an order is placed. If your customers have questions about how Shop Pay works, or how their data is stored, then you can send them to the Shop Pay Help Center page.

That's it! You have now successfully enabled the Shop Pay feature on the Smart Cart. You can navigate to your store to see the Shop Pay in action as seen in the above screenshot.

We also have accelerated checkout options that can be enabled for Smart Cart. You can find the directions on how to accomplish that in this article.
