What Is a QR Code?
Before diving into the “how,” let’s cover the “what.”
QR code stands for Quick Response code. It’s a type of barcode that stores information—like a website link, contact info, Wi-Fi password, payment URL, or location data—that can be quickly read by a smartphone camera.
They look like a square made of black and white patterns. When scanned, your iPhone reads the data inside and takes appropriate action—like opening a webpage or joining a Wi-Fi network.
