產生您的 WiFi QR Code
QR design & error correction options
🔒 100% Client-Side Privacy: Your WiFi SSID and password are processed directly in your browser using local cryptographic functions. Credentials are never sent over the network.
Beyond static QR codes: captive portals & private PSKs
Shared QR codes leak passwords and lack compliance. Purple delivers branded captive portals, automated CRM capture, and per-tenant private PSK (iPSK) on Cisco Meraki, Aruba, Ruckus, and UniFi.
一掃即連
WiFi QR Code 將網路名稱、安全性類型和密碼編碼為 iOS 和 Android 相機可原生讀取的格式。訪客只需將相機對準它並點擊即可加入，無需讀出或手動輸入密碼。您可以將其列印並放置於接待櫃檯、飯店客房、會議室或咖啡廳桌面。
此工具為您提供
- 支援 WPA/WPA2/WPA3、WEP 和開放網路，以及隱藏的 SSID。
- 提供清晰的 SVG 和高解析度 PNG 下載，適合任何尺寸的列印。
- 完全在用戶端執行。您的網路名稱和密碼絕不會離開瀏覽器。
WiFi QR code syntax and URI specification
Modern smartphone cameras (iOS 11+ and Android 10+) parse wireless network configurations using the standardized MeCard / ZXing wireless URI scheme. Each parameter in the string is separated by a semicolon and terminated with a double semicolon.
| Parameter | Field Name | Syntax & Examples | Description |
|---|---|---|---|
| WIFI: | Scheme Header | WIFI:... | Declares the barcode payload as a wireless network configuration string. |
| S: | Network SSID | S:MyNetwork; | The service set identifier (network name) broadcast by the access point. |
| T: | Authentication Type | T:WPA; | T:WEP; | T:nopass; | Encryption protocol: WPA (covers WPA/WPA2/WPA3-Personal), WEP, or nopass for open. |
| P: | Pre-Shared Key | P:SecretPassphrase; | Network passphrase or security key. Special characters (;, :, \, ") must be backslash-escaped. |
| H: | Hidden Network Flag | H:true; | H:false; | Optional boolean flag indicating whether the SSID is hidden and does not broadcast beacons. |
| ;; | Payload Terminator | ;; | Double semicolon terminating the wireless configuration record. |
Static WiFi QR codes vs enterprise captive portals vs iPSK
Choosing the right onboarding method depends on your venue size, security requirements, and visitor engagement goals. Compare how static QR codes stack up against managed captive portals and dynamic Identity Pre-Shared Keys (iPSK).
| Feature | Static QR Code | Purple Captive Portal | Identity PSK (iPSK) |
|---|---|---|---|
| Primary use case | Small cafes, home offices, private meeting rooms | Public venues, retail, hospitality, healthcare, events | Student housing, build-to-rent (BTR), multi-tenant units |
| Authentication method | Shared pre-shared key (PSK) | Web login, SMS OTP, social auth, or email verification | Unique dynamic pre-shared key per user or apartment |
| Password security | Shared password easily leaked or forwarded | No shared password; dynamic session authorization | Private key isolated to specific resident devices |
| Client device isolation | Requires manual AP client isolation configuration | Built-in network isolation and firewall ACLs | Dynamic VLAN/micro-segmentation per resident |
| Visitor insights & CRM data | Zero data capture or visitor analytics | Real-time footfall, dwell time, CRM sync (HubSpot, Salesforce) | Resident device mapping and bandwidth management |
| Regulatory compliance | No terms of service or GDPR/CCPA acceptance | Automated legal compliance, opt-in consent, and audit logs | Tenant privacy compliance and audit readiness |

常見問題
WiFi QR Code 在 iPhone、iPad 和 Android 上是如何運作的？
當行動裝置相機掃描符合標準無線網路 URI 格式（WiFi:S:SSID;T:WPA;P:password;;）的 WiFi QR Code 時，作業系統會直接解析網路憑證。iOS 和 Android 會顯示原生通知提示，詢問使用者是否要加入網路。點擊提示即可自動連接裝置，無需手動選擇 SSID 或輸入密碼。
使用此線上工具產生 WiFi QR Code 安全嗎？
是的。此工具完全在用戶端運作，使用您網頁瀏覽器中的 JavaScript。您的網路 SSID、安全性加密類型和預先共用密碼絕不會傳輸到我們的伺服器，也不會儲存在任何資料庫中。SVG 和 PNG 圖片皆在您的裝置上本機產生。
支援哪些 WiFi 安全性加密類型？
此工具支援 WPA、WPA2 和 WPA3-Personal (SAE/PSK) 網路、舊版 WEP 網路以及開放未加密網路 (nopass)。它也支援隱藏網路廣播標記。
我可以為隱藏的 SSID 產生 QR Code 嗎？
是的。啟用「隱藏網路」選項會在 QR 承載資料中加入 H:true 參數。掃描時，支援的用戶端裝置會在網路關聯過程中專門探測該隱藏的 SSID。
為什麼商業場所會從靜態 QR Code 升級為 Purple 強制入口？
雖然列印的 QR Code 對於小型辦公室很方便，但大型公共場所、飯店和零售品牌在使用共用密碼時會面臨安全和營運挑戰（例如頻寬濫用和無法獲取訪客洞察）。Purple 以品牌專屬的強制入口、自動化 CRM 潛在客戶獲取、符合 GDPR/CCPA 規範以及 802.1X 私人 PSK (iPSK) 驗證，來取代靜態憑證。
Running guest WiFi at scale?
A printed QR code is the easy bit. Purple adds branded captive portals, data capture, and analytics on top, so guest WiFi becomes a marketing channel across every venue.
