ABSTRACT:
An inexpensive encryption device, system and method includes coded alphanumeric characters preprinted according to different key codes on mail-out forms that can be manipulated by a prospective user to yield encrypted data that can be returned over unsecure transmission channels for secure decryption by the operator of a computer-secured operating system. Error-correcting encoding is included to obviate the effects upon telephone keypad entry of secured data that includes error-prone alpha and numeric characters.
