    Understanding QR codes

    QR codes, also known as Quick Response codes, are two-dimensional barcodes that can be scanned using a QR code reader or smartphone camera. Invented in 1994 by a Japanese company, QR codes were initially used to track parts in vehicle manufacturing. However, with the rise of smartphones, QR codes have become increasingly popular and have found their way into different industries.

    How do QR codes work?

    QR codes comprise of black squares arranged on a white background with a square shape. These codes can store different types of information such as website URLs, product details, contact information, and other data. The information is encoded within the QR code, and when scanned by a reader, the information becomes available. QR codes work on the principle of reflection and absorption of light, and the scanner emits light on the board, and the black squares absorb the light, while white squares reflect back the light. This reflection and absorption process provides the QR code with the necessary information that helps to decode the data.

    Different types of QR codes

    There are several types of QR codes, and they include:

    • Static QR codes – this does not change, and the information embedded within the code is permanent
    • Dynamic QR codes – can be edited and updated if the information changes over time
    • Custom QR codes – can be designed with custom colors and logo

    Benefits of using QR codes

    QR codes have numerous benefits, and some of these include:

    • They are easy to use and require no typing
    • They can store large amounts of information in a small space
    • They offer a seamless transition between offline and online mediums
    • They can be tracked and analysed for marketing purposes

QR codes can also be used to share information with employees and to allow easy access to training manuals, documents, and other resources.
