What is a QR Code?

A QR code is a square-shaped barcode that consists of black modules arranged in a specific pattern on a white background. The code can store up to 2,953 characters, making it an ideal tool for sharing information, promoting products or services, and providing access to digital content.

How Does a QR Code Work?

When you scan a QR code using your phone’s camera, the code is decoded, and the stored information is retrieved. This process involves several steps:

1. QR code generation: A QR code is created with specific data, such as a URL or text message.
2. Scanning: The QR code is scanned using a smartphone’s camera.
3. Decoding: The scanned code is decoded, and the stored information is retrieved.
4. Action: The retrieved information is processed, opening a webpage, sending an email, or performing another action.

Importance and Use Cases

QR codes have numerous applications across various industries:

1. Marketing: QR codes can direct customers to landing pages, promotional content, or exclusive offers.
2. E-commerce: QR codes enable easy access to product information, reviews, or even online shopping platforms.
3. Travel: QR codes provide quick access to boarding passes, hotel reservations, or tourist information.
4. Healthcare: QR codes can store medical records, prescriptions, or emergency contact details.
