A QR code, short for Quick Response code, is a type of two-dimensional barcode that contains data in both the vertical and horizontal directions, allowing it to store a larger amount of information compared to traditional one-dimensional barcodes. QR codes can encode various types of data such as text, URLs, contact information, or other alphanumeric data. They are widely used for mobile marketing, product packaging, event ticketing, digital payments, and many other applications. QR codes can be scanned using smartphones, tablets, or dedicated QR code scanners, enabling users to quickly access information or perform actions by simply scanning the code with a compatible device.
