CodeScanner

Barcode and QR code scanners are available in plenty in app markets, but most of them are paid, in-app-purchase required, or full of ads. Here is a simple and totally free app for barcode scanning and QR code scanning. If the scanned result is a url, you can open it by clicking on the result or if it is an e-mail id, then you can start your favourite email app by clicking on it. Or if you want to share the data you can past it directly by pasting clipboard commands.

So here is CodeScanner, the free code scanner for android.
Its lightweight
easy to operate
android 10+ compliant.....
Have fun....
