pl-global-card

All newly issued Brex cards will now be further protected with 3 Domain Secure (3DS), a card industry security protocol for online transactions. It’s a way to ensure that the person attempting the transaction is actually the cardholder. It does this by adding an extra verification step (OTP) before processing the transaction this helps to prevent card-testing attacks.
