What Is a QR Code?
Essentially a QR code is a machine-scannable image similar to a bar code that can be immediately read using a smartphone camera. QR codes come with several black-and-white symbols placed horizontally and vertically which convey certain pieces of information.
When a camera from a Smartphone scans the QR code, it translates that information into something that humans can easily understand. Unlike bar codes, QR codes can hold over a hundred times more information including email addresses, phone numbers, website URLs, and more.
