QR Code Tips & Best Practices

1. Best ways to use QR codes for your business

If you run a small business, freelancer service or local shop, a well-placed QR code can connect offline customers with your most important online links.

• On business cards: use a multi-link QR that opens your website, WhatsApp, Google Maps location and social media profiles.
• On brochures and posters: link to your latest offer, online booking page or product catalog so people can act immediately.
• For limited-time campaigns: create QR codes with an expiry date using MultiLinkQR so old codes stop working after the promotion ends.

Instead of printing multiple QR codes, you can keep everything in one code and update the links in a new multi-link QR whenever your campaign changes.

2. How to create a QR code for your online portfolio

Designers, developers, photographers and freelancers often need to share several links at once: portfolio, LinkedIn, GitHub, Behance, Dribbble, resume and contact form.

A multi-link QR code lets you share all these profile links from one place. When someone scans your QR, they see a clean landing page with buttons for each destination.

1. Open the MultiLinkQR generator.
2. Add each of your HTTPS links with clear labels such as “Portfolio”, “LinkedIn” or “GitHub”.
3. Choose a color that matches your personal brand.
4. Generate and test your QR code on a few different phones.
5. Place the QR on your CV, portfolio PDF, website and business card.

This makes it easy for recruiters and clients to find every important link without typing long URLs.

3. QR code on visiting card – design tips

Adding a QR code to your visiting card gives people an instant digital way to contact you. Follow these quick design tips for better scanning:

• Size: keep the QR at least 2 cm x 2 cm (around 0.8 x 0.8 inches).
• Contrast: dark QR on a light background works best. Avoid busy images behind the code.
• Safe margin: leave some white space around the QR so scanners can detect it easily.
• Call to action text: add a short line like “Scan for all my links” or “Scan to save my contact”.
• Testing: always test your printed cards with multiple phones before printing a large batch.

Because MultiLinkQR supports multiple links, you do not need separate codes for your website, contact and socials – one QR on your visiting card can handle everything.

4. QR codes for restaurants, cafés and events

Restaurants and event organizers can use QR codes to keep information updated without reprinting menus or posters.

• Link to digital menus, allergen information and special offers.
• Add links for online ordering, table booking and reviews.
• Create separate multi-link QR codes for different sections, such as drinks, food and desserts.

When your menu or price changes, you only need to update the links in your new multi-link QR, not the physical boards or table stands.
