    摘要: A method for authenticating a transaction includes replacing a first security value of a transaction device with a second security value; receiving, during a first transaction, the second security value; authenticating the first transaction based at least in part on the second security value; determining that a predetermined number of transactions have occurred during which the second verification value was not rewritten since the second security value was replaced; responsive to determining that the predetermined number of transactions have occurred, replacing the second security value on the transaction device with a third security value; receiving, during a second transaction, the third security value; and authenticating the second transaction based at least in part on the third security value.

    摘要: Embodiments of the method for authenticating may include causing an automated teller machine to replace a card verification value with an updated card verification value during a first transaction at the automated teller machine when a re-write condition is present, such as a request from an account holder, a determination that the security of the card was compromised during a prior transaction, a predetermined time interval has lapsed, a predetermined number of transactions have occurred since a previous time the card verification value was rewritten, and according to a predetermined geographical parameter. The updated card verification value may be stored as a current value in a verification value database. The method may include receiving a card verification request related to a second transaction, and authenticating, using verification logic, the second transaction by determining whether the card verification value for the second transaction matches the current value stored in the database.
