What is a QR code?
QR stands for Quick Response Code and it's a graphical representation of digital data that can be printed on platforms and then scan by various devices.
Quick Response Code is frequently used to track data and information on items in a supply chain and is also used in marketing and advertising campaigns.
After storing information, the QR decodes the data using a handheld scanner or using a scanning application that is present on mobiles or mobile cameras.
These codes store more data than a barcode. Usually, a barcode consists of numbers, characters, and symbols, while a QR code can hold up to 406 bytes of data or information. Now various versions and variations of QR codes are present and are customized for various purposes.
