3-D Secure provides an additional layer of security for eCommerce transactions prior to authorization. It enables the exchange of data between the merchant, card issuer and, when necessary, the consumer, to validate that the transaction is being initiated by the rightful owner of the account.
3-D Secure 1.0, developed and owned by Visa, has been in the market for 15 years. 3DS 2.0 is the new generation of the 3DS protocol, developed and owned by EMVCo.
