What is QR Code
A QR code is a short form for Quick Response code which is a type of barcode that can store information in a matrix of squares, which can be scanned and read by smartphones, QR code scanners, and other devices. Unlike traditional barcodes, which hold information in horizontal lines, QR codes hold data both horizontally and vertically, allowing them to store much more information.
How QR Code Works:
- A QR code is made up of black and white squares arranged in a grid pattern.
- When scanned with a device, the code is decoded into meaningful data (e.g., a URL or text).
- The scanning device reads the code, interprets the data, and takes appropriate action (e.g., opening a website).
