How our site is protected
We use Secure Sockets Layer (SSL) for secure transmissions. SSL applies encryption between two communicating applications, such as your PC and our corporate Internet server. When your data is transmitted over the Internet, it is encrypted or “scrambled” at the sending end and then decrypted or “unscrambled” at the receiving end. We use 128-bit encryption.
Our secure servers are protected by numerous firewalls, which are constantly monitored to help prevent security breaches.
1 Emergency card replacement outside the continental U.S. may take a minimum of 48 hours. There may be a service fee associated with a request for 24 hour card replacement.
