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.
