PowerPoint slide advance?

I am preparing to give a presentation about my experience getting an xNT tag implanted. I thought it might be cool to advance my PowerPoint slides by scanning my hand on my ACR122. Any idea how I could do this?

You’d need custom software. The ACR122U is a PC/SC device and would need special drivers and then software to talk to the reader and the inject keyboard commands to the OS on a successful “card insertion” event.
