What is Barcode?
A barcode is a machine-readable representation of data, typically used to identify products. It consists of a series of vertical bars and spaces of varying widths, which encode information such as a product’s unique identifier (like a UPC code) or other details. When scanned by a barcode reader, the information is quickly retrieved, allowing for efficient inventory management, sales tracking, and data collection in various industries. Barcodes can be found on packaging, labels, and tickets, making them a fundamental part of modern commerce.
How to work Barcode?
Barcodes work by encoding information in a visual format that can be easily scanned and read by machines. Here’s a simplified overview of how they function:
Encoding Information: A barcode represents data (like a product number) using varying widths and spacing of parallel lines (bars). Different patterns correspond to different characters or numbers.
Scanning: A barcode scanner emits a beam of light (usually a laser or LED) that reflects off the barcode. The scanner detects the light reflected back, interpreting the varying widths and spaces.
Decoding: The scanner translates the pattern of light and dark into digital data. This process converts the barcode back into the original information it represents, like a product ID.
Data Processing: The decoded information is sent to a computer system, which can retrieve details from a database, like product name, price, and stock levels.
Applications: Barcodes are used in various settings, such as retail (for sales), logistics (for tracking shipments), and inventory management.
Overall, barcodes streamline the process of identifying and managing products efficiently.
