3D Secure (3DS)
An extra authentication layer for online card payments that verifies the cardholder, reducing fraud.
Last updated:
3D Secure (3DS) adds a verification step — such as a code or app confirmation — to online card transactions. It shifts liability for fraud and is widely required by merchants and ad platforms.
Crypto cards on the Visa/Mastercard networks support 3DS, which is important for funding ad accounts and high-value online purchases.
