Understanding QR Codes

QR (Quick Response) codes are two-dimensional barcodes that can store URLs, text, contact information, Wi-Fi credentials, and more. They were invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous in marketing, payments, and authentication.

Decoding a QR code involves image processing to locate the finder patterns, correcting for distortion, and reading the encoded data matrix. While this tool provides the user interface for uploads, full browser-based decoding typically requires a dedicated JavaScript library.

Frequently Asked Questions
