The Wix Stores checkout process is secured by HTTPS / TLS encryption and it is safe for your customers to purchase from your Wix site. 

TLS (Transport Layer Security) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and secure. TLS is the industry standard and is used by millions of websites in the protection of their online transactions with their customers.

Additionally, Wix Stores only works with payment gateways that offer the highest level of security certification (PCI DSS Level 1).

For more information about how payment information is encrypted and secured, please contact your chosen payment gateway.
