Our Site is secured by Rapid SSL:

Secure Sockets Layer (SSL) is a protocol for enabling data encryption on the Internet and for helping web site users confirm the owner of the web site. Up to 256-bit SSL encryption protects transactions and confidential data in transmission.

Encryption is a mathematical process of coding and decoding information. The number of bits (40-bit, 56-bit, 128-bit, 256-bit) tells you the size of the key. Like a longer password, a larger key has more possible combinations.

Your credit card data is protected by this encryption and SSL.
