Decimen is an open-source web app that moves files between devices through an animated QR stream, requiring no direct network connection, pairing, account, or native app.

I’m not sure when I’d use this, but its a neat concept

    Wi-Fi is already using light to transmit digital data. Shit, radio was transmitting data using binary with Morse code in 1895, also using light waves. Radio requires no direct connection, pairing, account, or apps.

      I wouldn’t use this day to day, but what I found cool was:

      • it doesn’t require cables or any additional equipment (including routers, cell towers)
      • it can’t be detected by anything, assuming you toss a blanket over the transfer

      The downside is that if you wanted to get it truly offline, you would need to have the an app installed on both devices ahead of time, if I understood it correctly. (Edit: bolded bits are new)

      It did lead to some fun discussion in this thread :)

        You did not. It’s a web application, it even says so in the snippet you used for the post. It runs directly in the browser, no need to install anything.

          That’s my bad for writing it poorly. I meant to say that about the premise of not needing internet, since someone who has internet on both devices might have better ways to transfer the files.

          Someone would need to plan ahead and install the PWA (or some compatible tool) in order for this to work
