    Introduction: What is a QR code?

    QR code or Quick Response code is a two-dimensional barcode that can be read by a smartphone camera. It was first invented in 1994 by Denso Wave, a subsidiary of Toyota, to track vehicles during the manufacturing process. QR codes are capable of storing large amounts of data, such as URLs, contact information, product information, and more. One of the benefits of using QR codes is that it allows information to be quickly and easily accessed by consumers.

    The History of QR Codes

    QR codes were first used in the automotive industry to track vehicles during the manufacturing process. However, it wasn’t until the rise of smartphones that QR codes became more widely used. In 2011, QR codes were integrated into the Apple iOS operating system, which allowed users to scan QR codes without the need for a third-party app. Since then, QR codes have become increasingly popular in advertising and marketing.

    How Do QR Codes Work?

    QR codes work by encoding data in a two-dimensional barcode that can be read by a smartphone camera. The data is stored in a series of black and white pixels that are arranged in a grid. When a smartphone camera scans the QR code, the data is decoded and displayed on the screen. QR codes can be used to store a variety of data types, including plain text, URLs, contact information, product information, and more.

    QR codes offer a number of benefits for both businesses and consumers. These benefits include:
