## What it is
A set of Vue.js 3 components for detecting and decoding QR codes and other barcode formats directly in the browser. It provides QrcodeStream (live camera scanning), QrcodeDropZone (drag-and-drop images), and QrcodeCapture (file upload) components.

## Use cases
- scan qr codes with the camera in a vue app
- decode qr codes from uploaded images
- add barcode scanning to a web page
- drag and drop an image to read a qr code
- continuously scan qr codes from a webcam stream
- read qr codes in the browser without a native app

## When to choose
- you are building a Vue 3 application and need in-browser QR/barcode scanning
- you want multiple input modes: live camera, drag-and-drop, or file upload
- you need unstyled, responsive components that fit your own layout

## When to avoid
- your project does not use Vue.js
- you need server-side or native mobile QR decoding
- you need a full-featured barcode inventory system rather than a decoding component
