How will it affect my credit card payments?

Many users have to enter passwords to confirm payments.

Often this appears in a pop-up box or in-site box, which has been criticised for causing confusion.

3D Secure 2.0 uses artificial intelligence and machine learning to flag payments as suspicious or safe.

Scrapping passwords or knowledge questions can prevent fraudsters from accessing users' credentials.

Some issues have been flagged in the current system with scam websites using fake pop-ups to trick customers into giving up their secure passwords.

Others experience friction or glitches when using the system with almost 70% of customers abandoning their purchases at this point.

The new system should streamline this as it is rolled out across companies.
