ELECTRONIC TRANSACTION NOTIFICATION SYSTEM AND METHOD

摘要

Systems and method are provided for delivering notifications to user regarding use of their authentication information. The delivery of notifications involves ascertaining a device identifier associated with a request received from a user device to engage in a transaction using the authentication information and comparing this device identifier associated with the request to a plurality of known device identifiers previously associated with the authentication information. Thereafter, a notification for a user associated with the authentication information can be generated and delivered, if the device identifier is not among the plurality of known device identifiers. In the systems and methods, contact information for delivering the notification is based on contact information for at least one previous transaction that meets a selection criteria and that is associated with the authentication information.
