QR Code Examples by Use Case

Last reviewed: 5 November 2026 by QRKit Editorial Team

Practical QR code examples for menus, events, business cards, packaging, education, support and asset labels, with testing advice for each.

A menu QR code should open quickly on mobile data and avoid large PDFs. Link to a lightweight page, keep the code at table distance, and test it on both iPhone and Android before printing table tents or stickers.

If the menu changes often, keep the URL stable and update the page behind it. The QR code itself cannot be edited after printing.

  • Use HTTPS and a short, readable URL.
  • Test the menu on mobile data, not only café Wi-Fi.
  • Print at least 3 cm wide for table use.

Events and registration

Event QR codes should lead to a page that works without an app download. Test the full journey: scan, open, register, and receive confirmation.

For calendars, verify the imported time zone on more than one device. For registration forms, check that the form is mobile-friendly and does not require a login.

Business cards and contact details

A contact card is most useful when it contains one reliable phone number or email, not every possible field. Test the contact preview on both major mobile platforms.

Avoid encoding private home addresses or personal mobile numbers unless you are comfortable sharing them with anyone who scans the code.

Packaging and product labels

Product codes should open quickly and work on small labels. Use a short HTTPS URL, choose a size suitable for the label, and test on the actual packaging material.

If the link may change, use a stable URL that you control. A QR code cannot be edited after it is printed on packaging.

Sources and methodology

This guide is based on QRKit's practical testing, public platform documentation, and common failure modes reported by users. Recommendations are conservative and should be tested on the exact devices, materials and print conditions you plan to use.
