3D Secure (3-domain structure), also known as a payer authentication, is a security protocol that helps to prevent fraud in online credit and debit card transactions so no payments go through unless you authorize them yourself.
Completing 3D Secure is as easy as entering your password or the one-time PIN sent to you via SMS in the required field.
If you're not receiving the One Time Password/PIN needed for payer authentication when making a card payment, don't worry! Just reach out to your bank for assistance.
Here are a few reasons why you might not be receiving your One Time Password/PIN:
- Change of Phone Number to receive OTP without updating the bank for static data updates .
- Change of Email address to receive OTP without updating the bank for static data updates .
- System issue facing the bank thus not sending the OTP .
