An authentication protocol developed by Visa and MasterCard to protect card payments on the Internet. The cardholder must register with the card-issuing bank.
For online credit card payments
3-D Secure is a method of ensuring the security of transactions. Mastercard, JCB and American Express also offer such a service under the names Identity Check (SecureCode), J/Secure and SafeKey. The risk of fraud and payment failure is significantly reduced with 3-D Secure. Another major advantage is that store operators who use one of these services are guaranteed receipt of payment. The procedure was developed for VISA (verified by Visa) and standardized by EMVCo.
The advantage for the customer is that the misuse of protected card data in e-commerce is greatly restricted, since no password is noted on the card and is therefore known only to the customer. With the classic method, unauthorized persons can make purchases on the Internet at the expense of others simply by possessing the credit card, as long as the card has not been blocked. With 3-D Secure, third parties also need a secret piece of information that is not noted on the card.
