The full form of the QR code is "Quick Response Code."
It is a type of two-dimensional barcode that can be read by a smartphone or scanner.
QR codes were developed in 1994 by Denso Wave, a subsidiary of Toyota, as a way to track vehicle parts during the manufacturing process.
The name "Quick Response" reflects the fact that the code can be read quickly by a scanner, and the large amount of data that can be stored in a small space.
The QR code allows the storage of more data than traditional barcodes and it can be scanned easily by a smartphone camera or a scanner.
