It's that time again: for the sixth time, the team at “TELNET - KLARTEXT REDEN” has organized the Waving Cat Challenge! Your task: get our waving cat (Kitty) to wave! You have to complete nine challenging tasks to win our most beautiful T-shirt. To do this, you need an RFID tag with a fixed UID (ISO 14443), which you can also get from us at our assembly. You'll also need some hardware that you can use for programming. And, of course, perseverance! Because it's not that easy.
