The full form of QR is Quick Response.
This acronym refers to the Quick Response code, a type of two-dimensional barcode that is machine-readable. QR codes are widely used because of their ability to store more data than a standard barcode and can be scanned quickly using a smartphone camera. This makes them suitable for a variety of applications, including:
- URL redirection: Leading users to websites.
- Contact information sharing: Easily sharing vCards.
- Payment processing: Facilitating mobile payments.
- Authentication: Verifying identity.
- Tracking and tracing: Managing inventory and logistics.
The "Quick Response" name reflects the code's primary advantage: its ability to be decoded rapidly.
