What are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that were first introduced in Japan in 1994 by Masahiro Hara, an engineer at Toyota. They were designed to track parts during manufacturing and were meant to be read quickly using a barcode scanner. Over the years, QR codes have evolved and become widely used for various applications, including marketing, advertising, inventory management, and more.

A standard QR code consists of three main components:

• Finder patterns: The square shapes at each corner of the code.
• Timing patterns: The small squares or dots that connect to the finder patterns.
• Data modules: The main body of the code where the data is encoded.
