First Claim
Patent Images
1. A method comprising:
- generating a verification value in response to a transaction involving a portable consumer device, wherein the verification value is generated using an application transaction counter, a first dynamic data element that is different from the application transaction counter, and a second dynamic data element that is different from both the application transaction counter and the first dynamic data element, wherein the first dynamic data element or the second dynamic data element comprises a non-random dynamic element; and
sending the verification value to a service provider with data in a magnetic stripe data format so that the service provider can verify the verification value.

Abstract
A method is disclosed. The method includes generating a verification value in response to a transaction involving a portable consumer device, where the verification value is generated using a first dynamic data element and a second dynamic data element. The verification value is sent to a service provider associated with the portable consumer device so that the service provider can verify the transaction.
