A Quick Response (QR) code is a type of two-dimensional barcode that stores information such as text, URL, email address, or even a contact card. These codes were first introduced in 1994 by Masahiro Hara and his team at Denso Wave, a Japanese company. The unique name “Quick Response” was chosen because it could read the data rapidly.

• Sharing contact information
• Linking to websites or social media profiles
• Providing coupons or promotions
• Storing medical information

The importance of QR codes lies in their ability to bridge the physical and digital worlds. They make it easy for people to access information, share data, or complete transactions using their mobile devices.
