Võrgukoodide

Võrgukoodid, also known as QR codes, are two-dimensional barcodes that can be scanned by smartphones and other devices to access information. They were invented by the Japanese company Denso Wave in 1994 and have since become widely used for various purposes. QR codes can store a wide range of data, including URLs, contact information, text, and even payment details. They are particularly popular in marketing, advertising, and event management, as they allow for quick and convenient access to information.

The structure of a QR code consists of black and white squares arranged in a square grid. The information encoded in the QR code is represented by variations in the modules (the black and white squares) within the grid. The size and complexity of the QR code can vary depending on the amount of data being encoded.

To scan a QR code, users typically need to use a QR code reader application on their smartphone. These apps can be found in the app stores of various operating systems, including iOS and Android. Once scanned, the QR code will direct the user to the corresponding information or action, such as opening a website or initiating a payment.

QR codes have become an integral part of modern technology, offering a quick and efficient way to share information. Their versatility and ease of use have made them a popular choice for businesses and individuals alike. As technology continues to advance, the use of QR codes is expected to grow, further integrating them into our daily lives.
