ABSTRACT:
A method, secure cell phone and system for securely accessing an automated banking machine using such secure cell phone. The secure cell phone includes a read only memory device in combination with two linear feedback shift registers for generating a unique security transaction code, which includes a cell phone identification concatenated with two pseudo random codes. The automated banking machine is called from the cell phone. One of the pseudo random codes is input into a software emulation of the cell phone circuitry running on the automated banking machine to generate a computed pseudo random code. This computed code is concatenated the input pseudo random code and a determined cell phone identification to generate a computed transaction code. The automated banking machine is securely accessed using the secure cell phone if the computed transaction code matches the unique security transaction code.
