Yes. The shopping-cart software runs in Secure Mode on the customer's browser, using SSL (Secure Sockets Layer) to encrypt sensitive data such as credit card numbers.

While selecting products and adding them to the Shopping Cart, the customer is in Non-Secure Mode. After he/she presses the Pay & Finish button, it will switch to the Secure Mode in order to collect the billing and shipping information.

All modern Web browsers support the SSL standard, but the customer can choose to checkout using Non-Secure Mode if necessary.
