Finder patterns: These are the square dots at each corner of the code, which help the camera detect the QR code.
Timing patterns: These are the alternating black and white lines that run horizontally or vertically through the code, helping the camera to orient the QR code correctly.
Data modules: These are the square modules that contain the actual data being stored in the QR code.

Importance and Use Cases of QR Codes

QR codes have numerous use cases across various industries. Some of their importance include:

Marketing and advertising: Businesses can use QR codes to provide customers with additional information about a product or service, such as promotions, discounts, or company details.
Education and training: QR codes can be used in educational settings to link students to additional resources, such as videos, images, or interactive simulations.
Supply chain management: QR codes can help track inventory levels, monitor shipping status, and provide real-time updates on product availability.
