What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can store text, URLs, contact information, and other data. Smartphones and tablets can scan QR codes instantly with their cameras, making them a fast way to share links, information, or actions without typing.
QR codes were invented in 1994 and have become widely used for sharing website links, connecting to Wi-Fi, making payments, accessing menus, sharing contact details, and more. They can store considerably more data than traditional barcodes and can be scanned even if partially damaged.

Frequently Asked Questions
How much data can a QR code hold?
QR codes can hold up to about 3,000 characters of text or 7,000 digits. Short URLs are ideal — shorter content makes the QR code simpler and easier to scan.
Can the QR code be printed in small sizes?
Yes, but very small QR codes (under about 2cm / 0.8 inches) may be hard for some cameras to scan. For print use, test scanning before finalizing.
Is my data private?
Yes. The QR code is generated entirely in your browser. Your text or URL is never sent to any server.
