QR Code Generator vs Barcode Generator 2D vs 1D Code Design — When to Use Each Format for Scannable Products
QR codes encode URLs, contacts, and WiFi passwords. Barcodes encode product SKUs. Both are scannable. But the data and scanners are completely different.
You need a scannable code on a product. QR code or barcode? A QR code encodes up to 4,296 characters and is scanned by phone cameras. A barcode encodes 12-20 digits and is scanned by laser scanners at checkout. Use QR codes for consumer-facing applications: marketing materials, menus, business cards, WiFi sharing. Use barcodes for supply-chain applications: product packaging, inventory management, retail checkout. The QR code is the consumer code. The barcode is the supply-chain code. Different data. Different scanners. Different codes.
