What is QR Code?
A QR code, or Quick Response code, is a two-dimensional barcode that can be read by a QR code scanner or a smartphone with a built-in camera and appropriate software. QR codes were first developed in 1994 by a Japanese company called Denso Wave.
QR codes can store much more information than traditional barcodes, including text, URLs, and other types of data. When scanned, the code is decoded and the stored information is retrieved. QR codes are often used for marketing purposes, allowing users to quickly access product information, websites, or other promotional material.
QR codes have become increasingly popular in recent years due to the widespread use of smartphones and the ease of scanning the codes using the phone’s camera. They can be used in a variety of settings, including advertising, packaging, and event promotions.

Why to decode QR Code?
QR codes need to be decoded in order to access the information that they contain. When a QR code is scanned, the code is read by a QR code scanner or a smartphone camera with a built-in QR code reader app. The scanner or app then decodes the information stored in the QR code and presents it to the user in a readable format.
Decoding a QR code is important because it allows users to access the information that the code contains, such as a website URL, product information, or promotional content. Without decoding the code, users would not be able to access this information.
Additionally, decoding a QR code can help businesses track the effectiveness of their marketing campaigns or product promotions. By using unique QR codes for different products or promotions, businesses can monitor the engagement and track the effectiveness of each campaign.
Overall, decoding a QR code is essential for accessing the information that it contains and unlocking the potential benefits of the technology, such as convenient access to information and promotional content.
