What are QR Codes?

A Quick Response (QR) code is a type of two-dimensional barcode that stores information in the form of black and white squares. Developed in 1994 by Masahiro Hara of Denso Wave, QR codes were initially used for tracking parts in manufacturing processes. Today, they’re ubiquitous in various industries, such as marketing, healthcare, and education.

Importance and Use Cases

QR codes offer several advantages over traditional barcodes:

• High storage capacity: A QR code can store up to 4,296 characters of information, making them ideal for storing URLs, contact details, or even small documents.
• Fast scanning: QR codes can be scanned quickly using smartphones and tablets with camera capabilities.
• Error correction: QR codes have built-in error correction mechanisms, ensuring that the data is accurately retrieved.

Some real-life use cases for QR codes include:

• Marketing campaigns: Businesses use QR codes to link customers to websites, social media profiles, or special promotions.
• Product tracking: Manufacturers embed QR codes on products to enable efficient inventory management and tracking.
• Healthcare: Medical professionals use QR codes to access patient records, treatment guidelines, or medication information.
