What Are QR Codes And How Do They Work?
QR codes, or Quick Response codes, are two-dimensional barcodes that can store information, such as URLs, text, or contact details. When scanned, these codes allow users to quickly access the encoded data without having to manually type it into their devices. QR codes are composed of black squares arranged on a white grid, making them easily recognizable and scannable.
The functionality of QR codes is rooted in their ability to be scanned by devices equipped with a camera and specific software, such as the QR code scanner integrated into smartphones. When you scan the code, the software decodes the data and directs you to the associated content or action, like visiting a website or saving contact information. This makes QR codes an efficient tool for sharing information in various scenarios, including marketing, event management, and product labeling.
How Can I Scan A QR Code With My IPhone Camera?
To scan a QR code with your iPhone camera, simply open the Camera app, which comes pre-installed on all iPhones. Ensure that the camera is pointed at the QR code, allowing it to fill the screen.
