Curable, silane-terminated polydiorganosiloxane-urethane copolymers exhibit the beneficial properties of isocyanate-terminated polysiloxane-urethane copolymers without the detriments associated with free isocyanate groups. The apparatus includes a registration controller for driving a print substrate at a registration velocity and feeding the print substrate to an image-retentive member. At least one of the latch bar and latch keeper is movable between a first position and a second position. The collars are slidably disposed upon the trunk, such that they can be pulled upwardly. A dynamic verification code may also be utilized in addition to, or in lieu of, a dynamic credit card number.
