Finsphere announced yesterday that the Affinion Group will serve as the exclusive distribution partner of its Mobile Transaction Monitoring service to financial institutions in the United States.

Here’s how it works:

“The service’s unique algorithm takes into account not only a user’s current location, but the historical location of the phone and previous financial transactions, as well as the transaction amount and merchant to determine whether the transaction is high-risk and whether to alert the user.  Once a user receives an alert, they can call the appropriate financial institution or an FCRA certified identity theft expert to get help in resolving any potential issues.”

The Affinion Group will offer the service as part of a suite that provides consumer protection from identity theft.
