Lovable + scanner
Browser-based QR scanning in a WebView is slow and permission-hungry. WebViewGold opens the native camera scanner from a link (<code>qrcode://</code> or <code>barcodescanner://</code>) and hands the result straight back to your Lovable app: a URL is opened automatically, a barcode value lands in a JavaScript variable.
From $109 one-time per platform, or let our team do it all from $698.
Event entry, class attendance, gym check-ins: the QR code contains a URL of your Lovable app with a token, the scanner opens it inside the app, your backend (Supabase or Lovable Cloud (Postgres, storage, edge functions)) validates it.
Inventory, product catalogs, price checks: the scanned EAN/UPC value is available as barcodescanresult and can fill a form field or trigger a lookup.
Members show a QR code, staff scan it with the same app. Both sides are plain pages in Lovable; the camera part is native.
Paste this into Lovable to implement the web-app side. Review the result, publish, then test inside the WebViewGold app.
Add native scanning for the WebViewGold app wrapper. 1) Create a route /scan/:code that looks the code up in a Supabase table scan_codes and shows the matching item; QR codes we print will contain that URL. 2) Add a Scan QR code button that sets window.location.href to qrcode:// when navigator.userAgent contains my custom WebViewGold token; otherwise hide it. 3) Add a Scan barcode button that sets window.location.href to barcodescanner:// and then polls the global variable barcodescanresult every 300 ms for up to 60 seconds; when it is set, query products by ean, show the product, and clear the variable. 4) Add an input fallback for manual entry.
With a good optimized version of your web app you can have a stunning mobile app within a couple of minutes. Additionally to that the customer service is very nice and very helpful! I can just recommend WebViewGold :-)
About 10 minutes plus your business logic.
A link or button that navigates to qrcode:// (QR codes, result URL is opened in the app) or barcodescanner:// (barcodes, result stored in barcodescanresult). Show it only inside the app by detecting the WebViewGold user agent.
For QR codes: encode a URL of your Lovable app (for example https://app.yourdomain.com/checkin?token=…); the app opens it like any navigation and your page does the rest. For barcodes: read barcodescanresult after the scanner closes and call your lookup in Supabase or Lovable Cloud (Postgres, storage, edge functions).
The WebViewGold projects already contain the camera usage description; adjust the text so it names your use case ("to scan tickets at the entrance"). Both stores read these strings.
With scanningmode://on, off or auto you control whether the scanner closes after the first hit or keeps scanning, useful for inventory counts.
A minimal handler for the barcode variable:
// button inside the app
function startScan() { window.location.href = "barcodescanner://"; }
// WebViewGold injects the result into the page
function onScannerClosed() {
if (typeof barcodescanresult !== "undefined" && barcodescanresult) {
document.querySelector("#sku").value = barcodescanresult;
lookupProduct(barcodescanresult);
}
}Only the camera permission with a purpose string, which the WebViewGold projects already contain. Describe the use case honestly in the string and in the App Privacy / Data safety answers if you store scan data.
Yes, with a JavaScript library. The native scanner is faster and uses the system camera UI; detect the app via the user agent and offer the native scanner there, the web library elsewhere.
The common 1D and 2D formats (EAN, UPC, Code 128, QR and more) through the native platform scanner frameworks.
Same result, different amount of work on your side. All three come with the approval guarantee and 24/7 human support.
