"3D secure" is a security protocol for credit card payments, which is required for all credit card payments at AmiAmi's webstore.
During the payment process, if you get an error message that 3D secure has failed, than can mean that either 3D secure has not been enabled for your credit card, or you have entered incorrect details when verifying the payment.
For assistance with enabling 3D secure for your credit card, please contact your credit card provider.
Important: Currently AmiAmi does not support 3D secure version 2, so you need to use version 1.
On some rare occasions we have been informed that certain credit card provider has stopped supporting 3D secure version 1, in which case you will either need to use a different credit card, or switch to a different payment method. (Currently there is no scheduled date for when 3D secure version 2 will become available at our store.)
