QR Code vs Barcode — What’s the difference?
Both store data, but they’re built for different purposes. Here’s when to use each.
QR Code
A 2D square code readable by smartphone cameras. Stores much more data than a traditional barcode — URLs, WiFi credentials, contact cards, and plain text. No special scanner needed.
Best for: Marketing, digital content, websites, WiFi sharing, business cards, menus, and anywhere a smartphone camera is the scanner.
Barcode
A 1D linear code read by laser scanners at retail checkouts and warehouses. Stores numeric product identifiers. Industry standard for retail, logistics, inventory, and supply chain management.
Best for: Retail products, inventory tracking, shipping labels, healthcare, and any system using point-of-sale or warehouse scanners.

Do Free QR Codes Expire?
Static QR codes — like the ones generated by SnapHQ — never expire. The destination URL is encoded directly in the code. As long as the URL remains active, the QR code works forever with no monthly fees or account maintenance required.
What Size Should a QR Code Be?
For business cards: minimum 2.5 × 2.5 cm. For flyers and brochures: 4 × 4 cm. For posters: 6 × 6 cm minimum. For storefront displays: 10 × 10 cm or larger. A useful rule of thumb — the maximum reliable scanning distance is approximately 10 times the width of the QR code.
Frequently Asked Questions
Are the QR codes and barcodes watermark-free? Yes. All codes are downloaded clean with no SnapHQ branding or watermarks.
Can I use the codes commercially? Yes — for product packaging, retail, marketing materials, and any commercial purpose.
Do I need a registered GS1 number for my barcodes? For retail sales in major stores, yes — your UPC/EAN numbers should be registered with GS1. For internal use, inventory tracking, or small-scale e-commerce, unregistered numbers often work fine.
