Before diving into scanning QR codes on screen, let’s quickly review what a QR code is:

• A QR code (Quick Response code) is a type of two-dimensional barcode consisting of black and white squares.
• It can store various types of data, such as text, URLs, email addresses, phone numbers, or even GPS coordinates.
• The size and resolution of the QR code affect its readability; typically, it’s best to scan a clear, high-resolution image.
