What is a QR Code?

A Quick Response (QR) code is a two-dimensional barcode that can store information such as text, URLs, contact details, or even connect to social media profiles. The concept of QR codes was first introduced in the 1990s by Masahiro Hara, an engineer at Denso Wave, and has since become widely used across various industries.
