Make a QR Code for Your Check-In and Booking Pages
The URLs for your public pages (bookings and check-in) are available through Settings > Public Pages:
Or Settings > Reservation Options:
Make sure to enable the page that you need and scroll down to hit the Save button.
Then, do a Google search for "QR code generator".
The one from Beaconstac looks good: https://www.beaconstac.com/qr-code-generator
Just put in your URL, make any customizations that are allowed in the free version, then download it. Post it around your location to help people get to your page!
