What Is a QR Code?

QR = Quick Response. Invented in 1994 by Denso Wave for automotive parts tracking in Japan.

A QR code is a two-dimensional matrix barcode that encodes data in black-and-white square patterns. Unlike traditional barcodes, QR codes can be scanned from any direction and hold up to 7,089 numeric characters or 4,296 alphanumeric characters. Modern uses include contactless payments, business cards, Wi-Fi authentication, product packaging, and marketing campaigns.

Frequently Asked Questions

What is a QR code?

A QR (Quick Response) code is a two-dimensional barcode that stores data in a matrix of black-and-white squares. It can encode URLs, text, contact information, WiFi credentials, and more. Most modern smartphone cameras can scan QR codes natively.

Can QR codes store WiFi passwords?

Yes. When you generate a QR code with the WiFi type, it encodes the network name (SSID), password, and encryption type (WPA/WEP) into a standard format. Scanning it with a phone camera will prompt the user to join the network automatically.

Are QR codes safe to scan?

QR codes themselves are harmless — they are just data. However, the URL or data they point to could be malicious. Always verify the URL before entering personal information. Most browsers now show a preview of the URL before opening it from a QR scan.

Disclaimer: QR codes are generated via the third-party QR Server API. Do not encode sensitive personal data such as passwords or financial information into QR codes.
