I mean, don't get me wrong, I'm sure it's a quality product that you provide (I'm assuming you're affiliated with this). I just don't remember the last time I had to give anyone access to my WiFi (everyone's just on mobile these days), and when it has been required it's usually for laptops (which couldn't use this.. Nor a QR code for that matter)
Maybe other people would find better use for this, but for the past years I've just set my WiFi password to something I remember and in the rare cases people want to connect, I just tell them the password.
The WiFi block looks nice though!
