QR Codes Are The New Black

It started when I saw a QR code (above) on my Tiktok.

I pointed my phone's camera at it and up came my Tiktok, much to my surprise.

When I added the Zello walkie-talkie app to my phone (free, the way we like it), I explored all the settings and noticed a QR-ish icon right under my photo (below).

I touched it and up came the QR code below.

Again, I pointed my phone's camera at it and just like with TikTok, up came my Zello.
