Barcodes are machine-readable, optical representations of data, primarily used to identify products and track information efficiently. They consist of parallel lines (1D) or patterns (2D) that, when scanned by light, are translated into numbers or letters by a computer.

Rapid Identification & Data Capture: Barcodes instantly identify items, eliminating manual entry and speeding up processes like checkout in retail or item retrieval in warehouses.
Inventory Management & Tracking: They allow businesses to track stock levels in real-time, monitor items throughout the supply chain, and manage shipping.
Accuracy Improvement: Barcodes significantly reduce human error associated with typing or tracking items manually.
Product Information Retrieval: They connect physical items to database entries containing prices, product names, and specifications.
Access Control & Verification: Used in ticketing for events or transportation, they verify validity, and in healthcare, they track patient records and medication. Barcode Types
Linear (1D) Barcodes: These are the familiar vertical lines of varying widths, such as UPC-A codes on retail products or EAN-13 codes.
Matrix (2D) Barcodes: These use patterns like dots, hexagons, and rectangles (e.g., QR codes) to store more data, including links to websites or contact information. How They Work
Scanning: A scanner (or camera) shines light onto the barcode.
Absorption and Reflection: The black bars absorb light, while the white spaces reflect it.
Conversion: The scanner detects this pattern of light/dark, converts it into a binary signal (ones and zeros), and sends it to a computer, which translates it into the corresponding alphanumeric characters.
