The present invention is directed to methods and devices for secure virtual credit card transactions. In one embodiment, a consumer system initiates a transaction with a merchant system. The consumer system generates a first verification code and a second verification code. The consumer system provides the merchant system with the first verification code. The merchant system transmits the first verification code to an authorizing entity, and the consumer system independently transmits the second verification code to the authorizing entity. The authorizing entity compares the verification codes received from both the consumer system and the merchant system. Based on the results of the comparison, the authorizing entity either approves or rejects the transaction.
