What are QR codes and how do they work?
QR codes, or Quick Response codes, are two-dimensional barcodes that store information in a black-and-white grid pattern. They can encode various types of data, including URLs, text, contact information, and more. When a device scans a QR code, the information stored within it is decoded and presented to the user. This technology was originally developed for the automotive industry but has since found applications in various fields, including marketing, logistics, and mobile payments.
The main advantage of QR codes is their ability to be quickly scanned with a camera or a mobile device, enabling instant access to information. Unlike traditional barcodes, QR codes can hold much more data and can be scanned from any angle, which increases their versatility in everyday use. With the widespread adoption of smartphones, QR codes have become a popular tool for bridging the gap between physical items and digital content.
