Source: https://www.taproo.com/wifi-qr-code-generator Wi-Fi QR code generator # Free Wi-Fi QR code generator For a cafe, holiday let or small business, Taproo can generate a free static Wi-Fi QR code containing the network credentials so compatible phones can offer to join after a scan. No guest app is required. If the Wi-Fi password changes, generate a new static QR; an editable Taproo web page is a separate option. Generate Wi-Fi QR — free Browse all QR & NFC use cases ## How do you create a Wi-Fi QR code? Enter the network name (SSID), security type and password, and the generator encodes those credentials in a Wi-Fi QR code. Compatible phones can then scan the code and offer to join the network without the guest typing the password. - What you needexact SSID (case-sensitive), security type (usually WPA/WPA2) and the password. - Works nativelymodern iPhones and Android phones can read standard Wi-Fi QR codes with built-in camera or QR features; exact prompts vary by device and OS version. - Guest networkspoint the code at your guest SSID so visitors never see the main password. - Hidden networkstick the hidden option or the code won't connect. - NFC optionNFC is a separate option: Android can support Wi-Fi records, while iPhone users should use the Wi-Fi QR code or a web-link NFC tag. ### Free, no signup, no watermark Download a clean PNG or SVG Wi-Fi QR code instantly — no account required for the static version. ### WPA / WPA2 / WPA3 + hidden SSIDs Works with any modern router and supports hidden networks via a single toggle. ### Add an editable page + NFC Use an editable Taproo Wi-Fi page when you want to update displayed network details without replacing the QR, or add compatible NFC hardware. ## How it works - 1 ### Enter your Wi-Fi details Type your SSID, password and pick the security type (WPA/WPA2/WPA3 or open). Tick 'hidden network' if your SSID isn't broadcasting. - 2 ### Download the QR code Get a high-resolution PNG or vector SVG, ready to print on a poster, table card or laminated sign. - 3 ### Stick it where guests need it Reception, meeting rooms, café tables, holiday-let kitchens. Optional NFC products can open the Wi-Fi page with a tap. Taproo shop ## Choose a dedicated Wi-Fi NFC product Magnetic and desktop 3D-printed PLA options for guest Wi-Fi access. Shop Wi-Fi products ## How a Wi-Fi QR code actually works A Wi-Fi QR code is just a QR encoding of a tiny text string in the formatWIFI:T:WPA;S:;P:;H:false;;— a standard recognised by iOS and Android. When a phone camera reads it, the operating system shows a one-tap prompt: "Join ?". The password is never typed, never seen, and never copied to the clipboard. Because the credentials live inside the QR itself, a printed static code keeps working with no internet connection on your end — guests' phones do the handshake directly with your router. The trade-off: if you change the password, the printed code stops working. An editable Taproo Wi-Fi page offers a different approach: its QR can open a web page showing the current network details. Update the page later and the QR still opens the same page. This is not the same as changing credentials embedded inside a static Wi-Fi QR. ## Where people use them ### Cafés, restaurants and bars Table talkers and menu cards with a 'Scan for Wi-Fi' corner. Guests connect before the drinks arrive — no staff interruptions. ### Holiday lets and Airbnbs Laminated welcome card in the kitchen. If the password changes, regenerate a static Wi-Fi QR or update the details shown on an editable Taproo Wi-Fi page. ### Offices and co-working spaces One sticker per meeting room for the guest VLAN. No more reading 24-character WPA keys out loud over a call. ### Events and pop-ups A4 print at the entrance for press, vendors and staff. An editable Taproo Wi-Fi page can show updated network details without changing the QR that opens that page. ### Salons, clinics and waiting rooms Discreet card at reception. Keeps the guest network separate from your booking system. ### Schools and community spaces Per-room QR for visitor Wi-Fi, with the password rotated termly from one dashboard. ## Static vs dynamic Wi-Fi QR codes  Static (this generator)Dynamic (Taproo account) PriceFree, no signupFree plan available Update displayed network details without reprintingNoYes — on the Taproo web page Scan analyticsNoYes Works offline at scan timeYesRequires network for credential fetch NFC optionWrite or pair separatelyCompatible Taproo NFC product ## Troubleshooting: when a Wi-Fi QR doesn't work - Camera scans the QR but nothing happens. The phone almost certainly doesn't trust the encoded security type. Re-generate with the right WPA/WPA2/WPA3 setting — picking "WPA" when your router is WPA3-only is the most common cause. - It joins, then drops immediately. Hidden network not flagged. Toggle "Hidden SSID" on and regenerate. - Special characters in the password. Quotes, semicolons, backslashes and colons need escaping. Our generator handles this automatically — if you hand-built the string elsewhere, regenerate it here. - Old Android phone (pre-Android 10) won't scan. Use Google Lens or a free QR reader app as a fallback, or print the password as text underneath the code. - Printed QR looks fuzzy. Print at minimum 2cm × 2cm and download the SVG, not the PNG, for any sign larger than A6. ## Frequently asked questions ### Is the Wi-Fi QR code generator really free? ### Do guests need an app to scan it? ### Does it support WPA, WPA2, WPA3 and hidden networks? ### Can I change the password later without reprinting? ### Will this work on my router or guest network? ### Can I use a Wi-Fi QR code in an Airbnb or holiday let? ### Does tapping an NFC tag join the Wi-Fi automatically? ### Should I use the Wi-Fi page or a Wi-Fi record on my tag? ## Related guides - Menu QR code generator - Digital business card - Event check-in QR code - All QR & NFC use cases
