Plugin(s)

  • Barcode Scanning
  • Face Detection
  • Face Mesh Detection
  • Selfie Segmentation
  • Subject Segmentation
  • Translation

Current problem

Currently, the plugin supports scanning barcodes and QR codes from images only on Android and iOS. However, in our cross-platform Capacitor app, many users access the app via the web, where camera access is not always available. This makes it impossible for them to scan QR codes from saved images, which is a key use case.

Preferred solution

It would be very helpful to add web support for scanning QR codes from images on device. This would ensure consistent functionality across platforms using a single plugin made for Capacitor.

Alternative options

  • Have tested out zxing/browser, which works, but is not very user friendly to set up. Using it also means multiple plugins needed for cross-platform use
  • zxing/library should work cross platform, but haven't managed to get it working with Capacitor.
