What to do with a transaction when the bank does not support 3D secure?

Question

Payment systems

Colleagues,

I encountered the following problem: there is a merchant that accepts only transactions with 3ds authentication, but, unfortunately, not all banks that issue cards support 3ds. What should the processor do in this case? Block a payment or make a payment without 3ds, and who is responsible in the second case in case of a chargeback?

Answer 1

usually block the transaction
