Patent attributes
Embodiments described herein disclose methods and systems for authorizing a payment card transaction using dynamic codes. The system can receive a request for authorization of a transaction using the payment card. The request can identify a verification code associated with the payment card and an identifier of the payment card, and the payment card can have an associated dynamic code accessible to a user via a channel. The verification code can be compared with a value of the dynamic code at the time of the transaction. The system can determine whether the user of the payment card accessed the channel within a time period prior to receiving the request for authorization. In response to the verification code matching the dynamic code at the time of the transaction and determining that the user accessed the channel within the time period prior to receiving the request, the system can authorize the transaction.
