Introduction to QR codes
QR codes have become increasingly popular in recent years, and you may have come across them in various places such as on products, billboards, or advertisements. QR codes, which stand for Quick Response codes, are two-dimensional barcodes that can hold a large amount of information including text, URLs, or even contact information. With the help of a smartphone, you can easily scan a QR code and access the stored information.
Understanding the working of QR codes
QR codes consist of black and white squares arranged in a specific pattern. These patterns are read by scanning devices such as smartphones, which can understand the code and decode the information. Each pattern has a unique reference that is used to decode the stored information. When you scan a QR code, your smartphone’s camera reads the pattern and sends it to a QR code reader app that decodes the information and displays it on your phone’s screen.

Using QR codes has several benefits, including:
- Efficiency: QR codes can store a large amount of information in a small space, making it more efficient than traditional barcodes.
