At AWS re:Invent, magician Doug McKenzie performed a magic trick where attendees selected a card, put it in their pocket without looking at it, and then received the correct card number via Twilio SMS. This was achieved using a few lines of code and decades of practice. The exact method behind the trick remains a secret, but it can be viewed by interested individuals. Doug McKenzie showcased his magic trick at the Twilio booth #1125 during AWS re:Invent.
