Individual card records in a cardlist file can optional specify a swipe speed.
This allows rapid testing of card readers. A negative swipe speed produces a backward swipe direction. The Ending Swipe Speed control allows simulation of a swipe that is accelerating or decelerating. The speed increase or decrease is applied linearly across the length of the swipe. The Virtual Card allows you to specify how many clock pulses are added to a swipe before it is sent to the card.
