Abstract: The invention provides systems and methods for ensuring security for a voting machine. The voting machine can include a display screen upon which numerous election choices are displayed for selection by a voter. A detachable printer can also be provided that is adapted to be securely attached to the voting machine and that prints the choices selected among the election choices to a print medium to generate a printed audit trail. A summary of the election choices visible on the display screen can be simultaneously compared with the printed audit trail by the voter poised in a voting position.

Abstract: A substrate, such as a banknote or travellers' check, carries a security device including in association at least one embossed transitory image, such as a latent or transient image and an embossed linear area. The arrangement is such that when the embossed region of the substrate is viewed from different angles each image and linear area can be visually discerned.
