Hi @Jiang10086, thanks for filing this request and sorry for the delay in responding here. I thought about this scenario before, and at first I was hesitant to implement an auto-launch because one of the security benefits of barcodrod.io is seeing and inspecting the barcode/QR code contents after decoding before using it for anything (good practice for QR codes with unknown/suspicious contents or origin).

That said, auto-copy to clipboard OR offering this as a configurable setting is a good compromise. I'll mark this as planned and look to include it in a future release.
