Скачать или смотреть QR Code vs Barcode: What’s the Difference? | 1D vs 2D Codes Explained (2025 Update)

📱 Ever scanned a QR code and wondered how it differs from a traditional barcode? This guide breaks down the key differences between QR codes and barcodes — including structure, data capacity, use cases, and how they’re transforming industries in 2025.

🔍 A barcode is a 1D (one-dimensional) code that stores data linearly and is commonly used in retail for product identification. In contrast, a QR code is a 2D (two-dimensional) code that can hold much more information — from URLs and contact info to payment data — all in a small square grid.

📦 While barcodes are scanned horizontally using laser scanners, QR codes can be scanned in multiple directions using smartphone cameras or 2D image scanners — making them ideal for contactless payments, marketing, inventory tracking, and digital authentication.

⚡ Whether you're a developer, business owner, or tech-savvy user, understanding the QR code vs barcode comparison helps you choose the right tech for your application — from logistics and supply chains to smart packaging and AR experiences.

💡 With rising global adoption of QR code technology for mobile payments, ticketing, and touchless check-ins, knowing the advantages and limitations of each format is more relevant than ever.
