What Are QR Codes and Why Are They Everywhere?

QR codes, or Quick Response codes, have become an integral part of our daily lives. From restaurant menus to payment systems, these two-dimensional barcodes have revolutionized how we share and access information.

Originally invented in 1994 by Denso Wave, a Japanese automotive company, QR codes were designed to track vehicles during manufacturing. Today, they have evolved far beyond their industrial origins to become a universal tool for connecting the physical and digital worlds.

How QR Codes Work: The Technology Behind the Squares

Unlike traditional barcodes that store data horizontally, QR codes store information both horizontally and vertically. This two-dimensional structure allows them to hold significantly more data - up to 4,296 alphanumeric characters compared to just 20-25 characters in a standard barcode.

Conclusion

QR codes have proven to be more than just a passing trend. Their versatility, ease of use, and ability to bridge physical and digital experiences make them an invaluable tool for businesses and individuals alike.
