Inspired by the original NFC Sharpie by Marc Kerstein, these NFC Sharpie takes the concept to a new level. Inside the genuine Sharpie body is a high-quality NFC tag. This design allows for quick and consistent activation in your handling.
During performance, simply bring the pen close to your spectator’s phone and it will instantly and silently trigger your chosen web magic app - such as Inject, Goo or Akronym - all without switches, typing, or suspicious moves.
No need to remember secret URLs or discreetly type anything. The NFC Sharpie handles the technical side so you can focus entirely on your presentation and performance.
Best of all, the pen remains completely innocent. It’s a genuine, fully functional Sharpie that can be handed to your spectator to sign a card or write a note. It looks, feels, and behaves exactly like a regular Sharpie - because it is one. The difference is what’s hidden inside. In your hands, it becomes an invisible tool that turns natural actions into powerful moments of magic.
A professional-grade tool for serious performers who demand both reliability and subtlety in their work.
