Credit card Security

FastSpring is regularly audited to ensure they comply with the Payment Card Industry Data Security Standard (PCI DSS), a set of requirements designed to ensure that ALL companies that process, store or transmit credit card information maintain a secure environment.

This means there is no risk of your personal data or credit card information being stolen. Using your credit card through a FastSpring page is 100% safe. They do not store credit card numbers, so there is no chance of unauthorized access or the numbers being stolen after a FastSpring purchase is completed.

For all purchases, FastSpring employs Verisign SSL Certificates that meet the highest standard in the Internet security industry for secure transations. An SSL Certificate establishes a private communication channel enabling encryption of the data during transmission. In addition, SSL Certificates allow Web browsers to clearly display a Web site’s organizational identity.
