Abstract
Abstract An encryption module for encrypting financial and other sensitive data may be conveniently interposed in series between a personal computer and the keyboard associated therewith. An application program designed to run on the PC is configured to prompt the user to enter his PIN or other confidential data into the encryption module; consequently the confidential data need not be transmitted in an unencrypted fashion, and need not reside on the PC hard drive in an unencrypted form.
