There is disclosed a method of processing a security item 1. The security item comprises a holographic security feature 2 having at least one metallised layer. The holographic security feature 2 is applied to the reverse of a substantially transparent film through which the holographic security feature is viewed in use of the security item. The transparent film protects the holographic security feature from the environment in the finished security item. The method includes the step of applying laser radiation to the metallised layer of the holographic security feature through the transparent film to remove a portion of the metallisation to define a pattern of identifying information on the holographic security feature. The method has the advantage that the hologram can be customised with identifying information after manufacture of the security item. |
