Card reader 2 includes a percentage indicator, support to using multiple cards during the simulation (i.e. not having to pause and reload after each card!), and a percentage indicator at the top, showing the percentage done.

This is different than the last card reader. You now control the reader. Hold right to go right and left to go back. You will notice a light to the left of the display. Pressing "j" will cause the light to turn red and the latch holding the reader still will move, allowing to to move it. Red means the latch is down, or not engaging, while green means the latch is up. The reader will automatically latch on, if you drive over it from right to left. The pen now has a fade time of 1 minute.

Simplified Instructions: Insert your card. Hold "j" to release the latch. Hold right arrow until you get to 25%, when you can release "j". Hold right all the way until 100%. Now remove the card. Hold left arrow to return to the beginning. After the pen fades, you are ready for your next card!
