SYSTEM AND METHOD INCLUDING DYNAMIC VERIFICATION VALUE

摘要

System and methods for generating a dynamic verification value for electronic payment transactions are disclosed. An account identifier and an account attribute associated with an account of a user are received at a server computer. A dynamic account attribute is created and concatenated with the account identifier. The concatenated account identifier and the dynamic account attribute are then used to generate a dynamic verification value. The dynamic verification value and the dynamic account attribute are then sent to a user communication device and used for authentication in a payment transaction.
