What is a QR Code?

A QR code (Quick Response code) is a type of barcode that stores information such as text, URLs, phone numbers, and even videos. It was invented in 1994 by Masahiro Hara, an engineer at Denso Wave, a Japanese company. QR codes were initially used to track parts in manufacturing but have since become widely used for marketing, advertising, and other purposes.

How Does it Work?

QR codes work by encoding information into a grid of black and white squares, called “modules.” The module pattern is what allows the QR code reader to recognize the code. When you scan a QR code using an Android phone’s camera, the QR code reader decodes the modules and retrieves the stored information.

Importance and Use Cases

QR codes are widely used in various industries and for different purposes:

• Marketing: Businesses use QR codes on promotional materials such as flyers, brochures, and posters to link customers to websites or social media pages.
• Advertising: Advertisers use QR codes to take customers directly to a website or landing page with special offers or promotions.
• Tracking: Companies use QR codes to track inventory levels, shipping information, and employee time tracking.
• Social Media: Social media platforms like Facebook and Twitter have incorporated QR code functionality into their apps.

Scanning a QR Code on an Android Phone
