  • Patent number: 5101097
    Abstract: Misaligned magnetic stripe cards are often improperly encoded during a write operation. The problem occurs most frequently in hand swipe encoders where the encoding operation may occur quickly without sufficient care to seat the card properly. A write - disable circuit responsive to the proper positioning of the card prevents such improper encoding, and destruction of valid encoding on adjacent tracks.

  • Patent number: 4742213
    Abstract: A card reader includes an opaque arm movable in response to the insertion of a credit card. The arm, when moved, interrupts a light path signalling the presence of the card thus permitting write or read operations on a magnetic stripe on the card. The use of arm permits highly reliable operation due to the location of the light path defining devices in a place where they are protected from contaminants. In addition, the light path is always interrupted with an obstruction of known opacity.

  • Patent number: 4692602
    Abstract: A multimedia reader and/or writer such as a credit card reader is adapted to receive media of different thicknesses, such as checks, cards and passports. The medium enters a channel defined by walls or rails, one of which includes a spring loaded section which adjusts to the different thicknesses. The medium moves against a wear plate which includes striations to guide the edge of the medium away from the spring loaded section in order to avoid catching the medium.
