Abstract

A system and method for enhancing the security of use of a transaction device such as a credit card through a telephone system wherein the subscriber may establish through the telephone network a series of parameters which must be satisfied in order to activate the credit card to permit validation by passage of the card through the conventional point-of-sale magnetic swiping device. The parameters may include subscriber establishment of an activation time frame, an activation area, a dollar limit on purchasing power, a temporary PIN valid subject to satisfaction of the other parameters, and voice verification.
