Understanding What a QR Code Is
A QR code is a type of square barcode that stores information. When scanned with a phone, it can open links, show text, connect to Wi-Fi, or perform quick actions.
How a QR Code Works
The pattern of black and white squares represents data. Your phone’s camera reads this pattern and translates it into information that an app or browser can use instantly.
Why QR Codes Are Popular
They are fast, easy to scan, and can hold more information than traditional barcodes. This makes them useful for menus, tickets, payments, and product details.
Where QR Codes Are Used
You see QR codes in stores, ads, events, and packaging. They allow quick access to websites, apps, and digital services without typing anything.
The Simple Takeaway
A QR code is a scannable square that stores data. Your phone reads the pattern and opens information instantly, making digital access fast and convenient.
