What is a QR Code?
A Quick Response (QR) code is a two-dimensional, machine-readable barcode consisting of black and white squares, designed to store data like URLs, text, or contact information. Unlike traditional 1D barcodes, they can be quickly scanned by smartphone cameras to immediately trigger actions, such as opening websites, connecting to Wi-Fi, or making payments.
Key Aspects of QR Codes:
- Origin: Invented in 1994 by Denso Wave, a Toyota subsidiary, originally to track vehicle parts during manufacturing.
- Functionality: They act as a physical-to-digital link, providing instant access to information without typing, often used in marketing, menus, and logistics.
- Capacity: They can hold significantly more data than traditional barcodes, including over 7,000 digits or 4,000 alphanumeric characters.
- Types: Static codes (fixed information) and Dynamic codes (editable information).
- Security: While useful, they can be used in phishing attacks, so it is recommended to verify the URL before acting on it.
Most modern smartphone cameras have built-in readers, making them a widely used, touch-less tool.
