Key Differences
A Barcode is a method of representing data in a visual, machine-readable form. It consists of a series of lines and spaces of varying widths that encode information. Barcodes are widely used in retail for product identification, inventory management, and tracking.
A QR Code, short for Quick Response Code, is a type of 2D barcode. Unlike traditional barcodes, QR Codes store data both horizontally and vertically, enabling them to hold more information, such as URLs, contact details, or text. QR Codes are commonly used in marketing, ticketing, and mobile applications.
Barcodes encode data by varying the widths and spacings of lines, limiting the amount of information they can carry. In contrast, QR Codes use a grid of squares to store data, making them capable of holding more extensive information.
Barcodes are primarily used for simple data like product numbers, while QR Codes are versatile and can store URLs, text, contact details, or even trigger actions on smartphones, making them suitable for a broader range of applications.
