What is the SET Secure Electronic Transaction™ technology?

The SET Secure Electronic Transaction technology, also known as SET™, is an encryption technology that helps protect the transfer of payment information over open networks, such as the Internet. Put simply, SET™ uses advanced security technology which allows cardholders to make secure payments to merchants on the Internet.

How does the SET™ technology help protect the transfer of payment information?

SET™ technology protects payment information in four ways:

First, it enables a cardholder to authenticate that a merchant is authorized to accept payment cards in a secure manner using SET™ technology.
Second, it enables a merchant that is using SET™ technology to authenticate the payment card being used in the transaction.
Third, SET™ technology uses an advanced encryption system to protect personal payment information during transfer over the network.
Fourth, SET™ technology makes sure the payment information is read only by the intended recipient. Information which can only be decoded by a merchant and a financial institution that both use valid SET™ technology.

With all these added safety features, both cardholders and merchants can feel safer when transferring payment information online.
