3D Secure (card verification code)

In Turkish: 3D Secure (3D şifresi)

The extra step when you pay online: your bank sends you a code or asks you to approve in its app to confirm it is really you.

Even if someone has your card number, the 3D Secure step stops the payment unless they also have your code or your phone. That is why the code must never be shared with anyone.

Read the message before you enter the code: it normally names the shop and the amount. If those do not match what you are buying, or someone on the phone asks you for the code, it is a scam.

What to do

  1. Never read the code out to a caller, a chat contact or a "seller".
  2. Check the shop name and amount in the message before you enter the code.
  3. If a code arrives that you did not ask for, call your bank on the number on your card.
