Quick Response (QR) codes are a type of two-dimensional barcode that has revolutionized the way we share information. Developed in Japan in 1994 by Masahiro Hara of Denso Wave, QR codes have become an essential tool for businesses, marketers, and individuals seeking to convey data quickly and efficiently.

What Are QR Codes?

QR codes are square-shaped barcodes consisting of a matrix of black squares on a white background. They can store various types of data, including:

• URLs (website links)
• Text
• Contact information (e.g., phone numbers, email addresses)
• VCards (electronic business cards)
• SMS messages
• Email addresses
• Wi-Fi network names and passwords
• Geo coordinates

QR codes are designed to be scanned using a smartphone camera app or specialized QR code readers. Once scanned, the encoded data is decoded and displayed on the device’s screen.
