Abstract
A key card encoder incorporates a plunger that is pushed downward as the card is manually inserted into a slot in the encoder and a potentiometer whose value changes based on the plunger position to indicate the card's position at all times. As the card is inserted into the slot, a head encodes a magnetic strip on the card as the card is inserted into the slot, while the head verifies the code in the reverse direction as the card is withdrawn from the slot. The slot is illuminated in different colors and flashing patterns to guide the user through the encoding process and notify the user if there is an encoding error.
