3D secure authentication is an added layer of security on all card payments, which redirects customers to a third party page to prove they have the autorisation to use the payment card being used.
We've started to see an increase of failed payments accross our website and other stores due to cardholders failing 3D Secure, which is thought to increase with business payment cards.
For more information on 3D Secure our partners at Ayko have written a more indepth guide.
