A Quick Response (QR) code is a type of two-dimensional barcode that can store various types of data, such as text, URLs, email addresses, phone numbers, and more. Scanning a QR code using your Android device allows you to instantly access the information stored within it.

In today’s digital age, QR codes have become an essential tool for businesses, marketers, and individuals alike. They provide a convenient way to share information, promote products or services, and even facilitate contactless transactions.
