Abstract: A portable consumer device includes a base, and a computer readable medium on the base. The computer readable medium comprises code for an issuer verification value and a supplemental verification value. The issuer verification value is used by an issuer to verify that the portable consumer device is authentic in an on-line transaction and the supplemental verification value is used to verify that the portable consumer device is authentic in an off-line transaction.

Abstract: A continuous web or laminate (32) of flexible material is indexed through a punch press (44) whereat holes of different shapes and sizes are punched in repetitive patterns through successive sections of the laminate. The laminate (32) is then moved beneath a light source (48) so that light passes through the holes and is sensed by a light-sensing camera (52) which laterally and cyclically scans at a rapid rate the underside of the moving laminate.During the rapid scanning by the camera (52), each hole may be scanned many times due to the size and shape of the hole. Consequently, light is sensed many times for the same hole and a corresponding number of signals are developed by the camera. A hole counting system (46), which receives the developed signals from the camera (52), includes a delay-and-compare circuit (66) wherein each signal related to a given hole is delayed by one scan cycle and compared with the next signal related to the same hole.

Abstract: In a card punch machine there is provided a photoelectromechanical punch checking system. A shutter is mounted on each punch pin in the card punch machine and movement of each shutter is monitored by a photoelectronic sensor. Signals from the electronic sensors are compared with data employed to select and actuate the punch pins to provide verification that the data signals have caused the selected punch pins to be actuated through a punching operation cycle.
