How to use QR codes for your business or restaurant

QR codes have moved from novelty to everyday expectation. Studies show that 89% of smartphone owners have scanned a QR code, and usage has only accelerated since contactless experiences became the norm. For businesses of any size, a well-placed QR code is one of the cheapest and most effective tools to bridge the physical and digital worlds — no app required on either end.

Best uses for restaurants

Restaurants were among the earliest mainstream adopters of QR codes, and for good reason. The use cases are immediate and practical.

• Digital menus — link to a PDF or mobile-optimised menu page. Update it any time without reprinting physical menus.
• WiFi passwords — encode your guest WiFi credentials directly into a QR code. Customers scan once and connect instantly, no typing required.
• Review links — link directly to your Google or Tripadvisor review page. Placed on the bill or table card at the right moment, this significantly increases review volume.
• Online ordering systems — link to your ordering platform so customers can browse and order from their own phone, reducing pressure on staff during busy periods.

Best uses for retail & shops

In retail, QR codes extend the shopping experience beyond what physical shelf space allows.

• Product information — link to detailed specs, ingredients, user manuals, or how-to videos that would never fit on a label.
• Loyalty programs — let customers sign up or check in to a loyalty scheme with a single scan at the register.
• Payment links — a QR code linking to a payment page offers a fast, contactless checkout alternative.
• Social media — link to your Instagram or TikTok profile so customers can follow you in-store while they're already engaged with your brand.

Best uses for service businesses

For consultants, tradespeople, therapists, and other service providers, QR codes turn paper touchpoints into digital ones.

• Booking links — add a QR code to your business card or invoice linking directly to your booking page. Customers can schedule while you're still in front of them.
• Contact cards (vCard) — encode your full contact details so a scan automatically populates the customer's phone contacts.
• Portfolio links — link to case studies, testimonials, or a project gallery for clients who want to see your work before committing.

Best practices for QR codes

• Test before you print — scan the code on multiple devices and in different lighting conditions before committing to a print run.
• Add a call-to-action — never leave a QR code without context. "Scan to see our menu" or "Scan to book a table" dramatically increases scan rates.
• Minimum size of 2.5 cm — smaller than this and many cameras struggle to read the code reliably, especially on older phones.
• High contrast colours — dark code on a light background is the standard for a reason. Avoid low-contrast colour combinations that reduce scannability.
• Include your logo — modern QR codes can include a centre logo without affecting readability. It reinforces brand recognition and builds trust.
