What are QR Codes used for on Packaging?

Short answer

For everything that doesn't fit on the packaging: detailed product information, user manuals, spare parts, disposal instructions, and reordering. Dynamic codes are almost always the right choice here, as packaging can be in circulation for years and the linked content may change.

Typical Goals

Complete product information that doesn't fit on the packaging
User manual, multilingual
Spare parts and accessories
Reordering
Disposal and material instructions
Authenticity verification

Why Dynamic

A package is in circulation for one to several years. During this time, instructions, contacts, and website structures change. A static code then leads to a dead end – on printed goods that cannot be recalled.

Design Considerations

Sufficient Size. On curved surfaces, more than the rule of thumb suggests.
Matte instead of Glossy. Reflection makes the code unreadable in stores.
Not on the Edge. The code must be flat and readable.
Short Note Next to It. "Instructions and Spare Parts" significantly increases the scan rate – a code without explanation is rarely scanned.

What is Often Forgotten

The target page must work on mobile. Those scanning in the store have a small display and a mobile connection. A PDF manual with 40 megabytes will not open.

Legal

For certain products, the law specifies what information must be on the packaging. A QR code can supplement this information but cannot replace it, as long as the regulation requires physical labeling.

Before switching mandatory information to a code, this should be checked.

Key facts

Almost Always: Dynamic codes due to long circulation time
Increases Scan Rate: A short note next to the code
Caution: Mandatory information cannot always be replaced
