QR codes (Quick Response codes) are two-dimensional barcodes that can store information such as text, URLs, and contact details. They were first developed in 1994 by Masahiro Hara of Denso Wave, a Japanese company, and have since become widely used for various purposes such as advertising, marketing, and tracking.

What is QR Code?

A QR code consists of a square grid of black and white modules that are arranged in a specific pattern. The code is read by a device using a camera or scanner, which decodes the information stored within it. QR codes can store a wide range of data, including:

• Text: URLs, phone numbers, addresses, etc.
• URLs: Hyperlinks to websites or web pages
• Contact details: Names, email addresses, phone numbers, etc.
• VCard: Electronic business cards that contain contact information

Importance and Use Cases

QR codes have become an essential tool in modern life due to their versatility and convenience. Here are some examples of how QR codes can be used:

• Advertising: Companies use QR codes on billboards, magazines, and other marketing materials to direct customers to their website or social media pages.
• Marketing: QR codes can be used as a tracking mechanism for promotional campaigns, allowing businesses to monitor engagement and conversion rates.
• Tracking: QR codes are commonly used in logistics and supply chain management to track packages and goods in real-time.
• Payment systems: Some companies use QR codes for contactless payments, eliminating the need for physical cards or cash.
