At their core, QR codes are two-dimensional barcodes consisting of black squares arranged on a white background. These squares encode data that can be interpreted by a scanner or a smartphone camera. Unlike traditional barcodes, which store data in a linear fashion and are limited in capacity, QR codes can store much more information in a compact space. This includes URLs, contact details, Wi-Fi passwords, and even plain text.
### The Rise of QR Codes in Modern Society

In retail, QR codes have transformed the shopping experience by enabling customers to access product information, promotional offers, and payment options simply by scanning a code. Restaurants have adopted QR codes to replace physical menus, reducing contact points and streamlining the ordering process.
In conclusion, QR codes have evolved from their humble beginnings in manufacturing to become a versatile and powerful tool in our daily lives. Their ability to quickly and efficiently convey information has made them indispensable across various industries, and their potential for future applications is vast. As technology continues to advance, QR codes will undoubtedly remain a vital component of our connected world.
