3D-Secure
An extra card-payment verification layer required by banks to reduce fraud.
3D-Secure (3DS) is an additional authentication layer that card networks and issuing banks apply to online card payments, typically via an OTP, banking-app push, or biometric confirmation. Branded as Visa Secure or Mastercard Identity Check, it shifts fraud liability from the merchant to the issuer once the cardholder authenticates, which is why banks and PSPs enforce it aggressively on card-not-present transactions in fraud-heavy verticals.
For buyers, 3DS matters in two places: funding ad accounts and user deposits. Cards that trigger 3DS on every top-up break automated spend workflows, so teams hunt for card providers with 3DS handled cleanly or disabled where legal. On the offer side, a clunky 3DS flow at the casino cashier kills Reg2Dep — a user who fails the OTP step is a paid click that never becomes a FTD.
In buyer speech
“These new cards throw a 3DS prompt on every Facebook top-up, so half the accounts stalled overnight — ask the provider for a 3DS-free BIN.”
