What is a QR Code?

A QR code (Quick Response code) is a type of barcode that can store information in the form of text, URL, contact details, or other data. It was invented in 1994 by Masahiro Hara of Denso Wave, and its name “quick response” refers to its ability to be read quickly.

Importance and Use Cases

QR codes have become increasingly popular in recent years due to their ease of use and versatility. Here are some examples of how QR codes can be used:

• Marketing: Businesses use QR codes on advertisements, flyers, and product labels to drive traffic to websites or landing pages.
• Payments: Mobile payment systems like Apple Pay and Google Wallet use QR codes for contactless transactions.
• Authentication: QR codes are used in various authentication processes such as 2FA (two-factor authentication), identity verification, and secure login.
