    Publication number: 20130030934
    Abstract: A user activity, which may be a credit card transaction or an on-line access, is approved based on the user's location at the time of the transaction or access. If the transaction or access is denied, the user may call or send a text message to the authorizing entity to permit the authorizing entity to determine the user's location. Then, the authorizing entity transmits a request to locate the user and receives location data indicating the location of the user in response thereto. If the user location is within a predetermined proximity to the location of the user activity, the user activity is authorized.
