Abstract
A system and method for enhancing the security of use of a transaction device such as a transaction card through a telephone system wherein subscribers to the service may require voice authentication as a prerequisite to a conventional transaction card authentication step. The service is automatically invoked based on a code inserted in the card, or the identity of the calling subscriber, or the identity of the called authentication bureau. The service may also be invoked in situations which do not involve the use of a transaction device but which require the input of an identifying password or number when seeking access to limited access data or services.
