ABSTRACT:
Information systems which provide access over a variety of devices (e.g. telephones, automated banking machines, computers) typically require that passcodes be numeric to allow entry on all device types. Alphabetic characters are associated with the numeric digits on both telephones and automated banking machines, allowing users to use mnemonic words to remember their numeric passcodes. Computer terminals do not have this association, creating user difficulties. The invention translates text entry on a computer keyboard into the equivalent numeric digits according to an appropriate mapping.
