QR code is the abbreviation for <<Quick Response Code>>. It is a black and white square-shaped code that enables people to scan it with a smartphone to learn more about a product or person.
The difference between QR code and barcode:
The device can recognize the QR code horizontally or vertically, but the barcode is designed to be read horizontally only.
A barcode can hold a limited number of data (12 digits maximum), while more than 4000 characters or numbers can be stored in the QR code.
The QR code was designed in Japan by auto marketers in 1994, and they have relied on it due to its large storage capacity and its ability to translate additional information to consumers beyond what conventional materials or packaging can convey.
