Abstract
A user inputs identification information in a terminal, and generates identification information and bar code information about a signature program. A receiver reads the bar code information of the user using a bar code reader. The bar code reader executes a signature program, generates signature information containing the identification information of the user, and requests a certification device to verify the signature information.
