Concept: What are QR Codes?

QR codes (Quick Response codes) are two-dimensional barcodes that store information in a matrix of black and white squares. They were first introduced in the 1990s by Masahiro Hara, an engineer at Denso Wave, a Japanese company. The purpose was to track parts during manufacturing, but soon their use expanded beyond the industrial sector.

QR codes have become ubiquitous in today’s digital world, used for various purposes such as:

• Sharing information
• Payment processing (e.g., Google Pay, Apple Pay)
• Shopping and product scanning
