3-D Secure

3-D Secure is a global payment authentication system that makes it difficult for fraudsters to make online purchases with stolen credit card details. When a buyer attempts to make a purchase, their bank will ask them to complete an extra security step, such as entering a one-time password or answering a security question. This helps prove that the buyer is really who they say they are and that their credit card details have not been stolen.

3D Secure is an important tool in the fight against online credit and debit card fraud. By confirming the identity of cardholders before approving transactions, it helps to prevent unauthorized use of cards and protect consumers' personal information.

While 3D Secure can add an extra layer of security to online payments, it is crucial to remember that no system is perfect. Fraudsters are always looking for new ways to circumvent security measures, so it is important to remain vigilant and report any suspicious activity to your bank or credit card issuer immediately.
