Introduction to QR Codes

Quick Response (QR) Codes have revolutionized the way we share information. Originating in the automotive industry in the 1990s for tracking vehicle parts, these two-dimensional barcodes have evolved into a versatile tool for storing a wide range of data.

How QR Codes Work

Unlike traditional barcodes, QR codes can store much more information and are readable from any direction. They work by encoding data in black squares arranged in a square grid, which can be read by an imaging device like a smartphone camera.

Common Uses of QR Codes

Today, QR codes are used everywhere, from marketing campaigns to personal use. They make connecting to Wi-Fi networks effortless, provide quick access to websites, enhance customer engagement in retail, and even facilitate contactless transactions.

Various Formats of QR Codes

There are several formats of QR codes, each serving different needs. URL QR codes direct users to a web page. VCard QR codes share contact information. Wi-Fi QR codes give access to network credentials. Text, email, and SMS QR codes are used for straightforward text messages, email addresses, or sending SMSes, respectively.
