SSL works by using a private, mathematical key to encrypt data that's transferred between your web browser and the web server. Netscape Navigator version 2.0 or greater. SSL automatically encrypts the HTTP transmissions between your browser and our site's server. When you type your credit card information into our online order form, no one except authorized Bureau of Engraving and Printing customer service staff can read it. It was supported initially by Mastercard, Visa, Microsoft, Netscape, and others.
SET enables merchants to verify that buyers are who they claim to be.
And it protects buyers by providing a mechanism for their credit card number to be transferred directly to the credit card issuer for verification and billing without the merchant being able to see the number. SET automatically encrypts the HTTP transmissions between your browser, our site's server, and the bank. When you type your credit card information into our online order form, no one except the credit card's issuing bank can decode it.
