QR Code

A Quick Response (QR) code is a type of barcode that can be read using smartphones or dedicated QR reading devices. Unlike traditional barcodes, which only use a series of vertical lines to represent data and can only store up to 20 numerical digits, QR codes are two-dimensional, meaning they contain information both horizontally and vertically. This 2D structure allows them to store up to 3,000 alphanumeric characters. This substantial increase in storage capacity makes QR codes ideal for encoding complex information like website URLs, contact details, and more. A QR code is typically square and consist of black squares arranged on a white background. QR codes have become a ubiquitous part of our digital world, used for everything from marketing campaigns to event ticketing. However, not all QR codes are created equal. There are two main types of QR codes: static and dynamic.
