Abstract
A method of recording a transaction relating to a security document is disclosed. Coded data portions are provided on the security document, with each coded data portion encoding an identity of the security document and part of a signature. The signature is a digital signature of the identity. A sensing device senses at least one coded data portion. From the coded data portion sensed by the sensing device a determined identity and a determined signature part are determined. The security document is authenticated using the determined identity and the determined signature part. Transaction data associated with the security document, stored in a data store, is updated upon successful authentication.
