I need to develop a simple php web page with QR Code scanner functionality. This page will be used to scan my customer's account number using qr code. As soon as a qr code is successfully scanned, the scanned text (account number) should be instantly posted to [login to view URL] page with the parameter "act_no".
The qr code functionality should be similar to [login to view URL] and should be quick in response. The page to be optimized for mobile usage.
