To operate ACR, all you need to do is drag the end of the card over the black circle near the end of the pink box. ACR will automatically take the card in, read it and display the binary, and spit it out the other end. It is safe to put another card in when the previous card falls off, or when the red box at the top goes away (it will only appear when you put a card in). I have included 2 cards which spell a secret message. Reset the binary between cards with the "m" key.
