Secure Electronic Transaction
SET, short for Secure Electronic Transaction, is a standard that will enable secure credit card transactions on the Internet. SET has been endorsed by virtually all the major players in the electronic commerce arena, including Microsoft, Netscape, Visa, and Mastercard.
By employing digital signatures, SET will enable merchants to verify that buyers are who they claim to be. And it will protect 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.
