How small can a QR code be on product packaging?

The minimum recommended size for reliable scanning is 2cm x 2cm (about 0.8 inches square), though 3cm x 3cm is better for consumer packaging. Test on the actual packaging material — glossy, curved, or textured surfaces may require larger codes. Always maintain adequate quiet zone (white space) around the code.

Should QR codes go on the front or back of packaging?

It depends on the purpose. Front-of-pack QR codes work for pre-sale information (ingredients, reviews) that influence purchase decisions. Back-of-pack or inside-pack codes work for post-sale content (setup guides, warranty, loyalty). Many brands use both positions for different purposes.

Can I update packaging QR codes after products ship?

Yes, with dynamic QR codes. The code printed on packaging redirects through a short URL that you control. You can update the destination anytime — add recall information, update instructions, swap seasonal content, or redirect to a new landing page — without changing the physical packaging.

How do QR codes help with product authentication?

Each product can receive a unique QR code linked to a verification database. When customers scan, they see confirmation of authenticity, manufacture date, and authorized retailer information. This is especially valuable for luxury goods, pharmaceuticals, and premium food products where counterfeiting is a concern.
