What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that stores information in a machine-readable format. QR codes were originally developed for tracking parts in automotive manufacturing but are now widely used across many industries including marketing, payments, logistics, and web applications.
QR codes can store various types of data including website URLs, text messages, contact details, Wi-Fi credentials, and payment links. Modern smartphones can easily scan QR codes using their built-in camera applications.
How QR Codes Work
A QR code stores information as a pattern of black and white squares. When a smartphone or QR scanner reads the code, it decodes the pattern and converts it back into the original information such as a website link or text message.
QR codes are designed to be scanned quickly and reliably even when partially damaged or viewed at different angles.
