A method for authenticating a security document having coded data thereon. The method includes, using a sensing device to sense at least one coded data portion, which is then used to generate indicating data. The indicating data is transferred to a computer system, which is responsive to determine, a received identity and a received signature part, from the indicating data. These are then used to authenticate the security document.
