What is a QR Code?

A Quick Response (QR) code is a two-dimensional barcode that stores information in the form of a square grid of black and white modules. Developed in 1994 by Masahiro Hara, a Japanese engineer at Denso Wave, QR codes were initially used to track parts during manufacturing. Today, they have evolved into a versatile tool for sharing information, accessing websites, and interacting with various digital platforms.

Store and share data: Use QR codes for inventory management, product tracking, or storing passwords.
Facilitate online payments: Generate a QR code to receive payments from customers.
