Accurate scanning of QR code APK

A QR code generator on your mobile phone can easily store the store's website address, store name, SMS, phone, email, and even a short article in the QR code. It is also fun to write your confession in the QR code, add the other party's photo in the middle, and send the QR code directly to her. Maybe the chance of success will be much bigger.
The generated QR code can be found directly in the album, and the saved path will be displayed when it is generated.
