▲ ▼ On-screen QR code/barcode scanner
QR code and barcode were originally invented to share data from physical material to digital medium. It worked great for getting information onto smartphones with the advent of good cameras. But, now QR codes are everywhere on the web and to access it we need another device to scan or take screenshot to scan with a QR code scanner app.
I would like a QR code scanner app which automatically scans the QR code on the screen (from web, social media, images etc.) and provides the data in return without having to manually take screenshot each time. The currently available apps which claim to do it don't work and are of very low quality.
In needgap, QR code is automatically generated here for each problem; so that the problem can be shared on web, chat for validation and those who view it on a computer can scan the QR via smartphone to get to the problem easily.
