WiFi QR Code: Collect Guest Details With No Hardware

September 6, 2026 2 views Barry Murphy
Print a QR code sign for each property. Guests scan it, fill in your WiFi guest form and receive the WiFi password. No hardware, no monthly fee, pay per scan, free on Simple and Premium Guides.

The WiFi QR Code is the no-hardware way to collect guest details with BetterSTR’s WiFi Marketing. You print a sign for each property, guests scan it with their phone camera, fill in your WiFi guest form and are shown the WiFi network name and password. Every guest who completes the form lands in your WiFi Guest Marketing list, the same list the full captive portal feeds.

What it costs

  • No monthly fee and nothing to buy. It works with the router you already have.
  • 20c per scan, charged to your BetterSTR balance only when a guest completes the form and receives the WiFi details.
  • A returning guest at the same property inside your Access Duration window (set in WiFi Settings, 5 days by default) is not charged again.
  • A scan that never becomes a completed form costs nothing.
  • Properties on BetterSTR Simple or a Premium Guide are included, so scans on those properties are free.

Charges appear on your Transactions page as “WiFi QR scan” with the property name.

Turning it on

  1. Go to WiFi Controllers → QR Code in your account, or open gb.betterstr.com/members/wifi/qr-codes.php.
  2. Switch the toggle on for each property you want a sign for. For a property that isn’t on Simple or a Premium Guide you need a positive balance or a payment method on file, because each scan is charged as it happens.
  3. Check the WiFi details guests receive column. If it says Not set, click Set WiFi details (or the pencil icon) and enter the network name and password. This edits the same WiFi Credentials as the property edit page, so your guidebook picks them up too. Leave a field blank to use your account default.

You can also switch the QR code on or off from the WiFi Marketing – QR Code card on each property’s page under Property Guidebooks.

Printing your sign

  1. Click QR code on the property row. A gallery shows each design with your property’s own code.
  2. Pick a design. There are six: a plain Classic “Free Wi-Fi” layout with an adjustable QR size, and five illustrated welcome posters (Botanical, Beach, Alpine, Tropical and Mediterranean) with a fixed QR size.
  3. Switch Include property name on if you want the name on the sign.
  4. Choose Download PNG for a print-quality image, or Print A4 to print straight to an A4 page. Copy link copies the URL inside the code if you want to share it another way.

We suggest fixing the sign to the fridge, then telling guests in your guidebook and arrival messages to scan the code on the fridge for the WiFi.

Regenerating a code

The circular-arrows button generates a new code for that property. Anything you have already printed stops working the moment you do this, so only use it if a sign has gone missing or you want to retire an old one. Switching a property off also stops its printed codes until you switch it back on.

What guests see

Scanning the code opens the property’s guidebook with the Connect to WiFi section open, or the lean sign-in page if you have Disable Guidebook ticked in WiFi Settings. Guests fill in the same form as the captive portal, controlled by your guest form settings: name, email, phone, marketing consent and an optional access code. On submit they see the network name and password with copy buttons and a tap-to-join QR code.

What it can’t do

Because your router keeps a normal password, the QR code can’t guarantee every guest fills in the form: someone who already knows the password, or is told it by another guest, can skip it. And with no controller on the network, email addresses can’t be verified, since there is no way to disconnect a guest who typed a fake one. Email verification and abuse protection are therefore off for QR guests.

Each device is limited to a handful of attempts per code every ten minutes, and if your balance can’t cover a scan the guest is asked to contact you for the password instead of receiving it.
