QR Codes for Restaurants and Food Apps

Restaurants adopted QR codes at scale during 2020 for contactless menus, and they have stayed. But a QR code that opens a PDF menu is a missed opportunity. QR codes can drive app downloads, enable mobile ordering, connect to loyalty programs, and collect customer data. This article covers practical strategies for restaurants and food delivery apps.

Beyond the PDF Menu

A QR code on a table tent that opens a PDF is the baseline. Here is what restaurants can do instead:

QR Code Type	Destination	Business Value
Digital menu	Web app or PWA	No app download required, always updated
Mobile ordering	In-app order screen	Faster service, higher order accuracy
App download	App store page with deep link	Drives installs, enables future marketing
Loyalty signup	In-app loyalty enrollment	Captures customer data, repeat visits
Review request	Google/Yelp review page	Social proof for new customers
Feedback form	In-app survey	Private feedback before it goes public

Placement Strategies

Table Placements

Table tents and table stickers are the highest-visibility spots. Every seated customer sees them.

What works:

• Clear call to action: "Order from your phone" or "Join our rewards" beats "Scan me."
• One QR code per purpose. A table tent with three QR codes confuses customers. Use one code that leads to a landing page with multiple options, or rotate between single-purpose tents.
• Durable materials. Laminated cards or acrylic table stands resist food and liquid spills.

Sizing: QR codes on table tents should be at least 2 cm x 2 cm (about 0.8 in x 0.8 in). For a typical scan distance of 20-30 cm, this provides reliable scanning even in low light.

Menu Integration

Print QR codes directly on physical menus:

• Next to specific dishes: "See this dish on video" linking to a short clip in the app.
• At the bottom of the menu: "Order ahead for your next visit" linking to the app.
• On the back cover: "Join rewards and get 10% off" linking to loyalty enrollment.

Receipts

Print a QR code on every receipt:

• "Rate your experience" linking to a feedback form.
• "Reorder this meal" linking directly to the items they just ordered, pre-loaded in the app's cart.
• "Download our app and earn points on today's order" with a deferred deep link that credits the visit retroactively.

Packaging (Takeout and Delivery)

Takeout bags and delivery boxes are marketing surfaces:

• Sticker on the bag: "Track your next order in real time" with an app download QR code.
• Printed on the box: "Exclusive app-only deals" with a deep link to the deals section.
• Insert card in the bag: "Get $5 off your next order" with a promo code deep link.

Window and Door Signage

Foot traffic sees the exterior:

• "Skip the line, order ahead" with a QR code linking to the app's order screen.
• "View today's specials" with a QR code linking to a daily specials page.

Deep Linking from QR Codes

A QR code that opens the app store is fine for first-time users, but returning customers should go directly to the relevant screen in the app.

Smart Routing

The QR code URL should detect whether the app is installed:

1. App installed: Open the app directly to the relevant screen (menu, order, loyalty).
2. App not installed: Show a landing page or redirect to the app store.

This is standard deep linking behavior. The QR code URL (e.g., https://yourdomain.com/menu) is configured as a Universal Link (iOS) and App Link (Android).

Contextual Deep Links

Different QR codes in different locations can carry context:

https://yourapp.com/order?location=downtown&table=12
https://yourapp.com/order?location=uptown&table=5
https://yourapp.com/menu?location=downtown

The location and table parameters let the app:

• Pre-select the correct restaurant location.
• Associate the order with the physical table.
• Show location-specific menus and pricing.

Driving App Downloads

The Value Exchange

Customers scan QR codes when they get something in return. Effective incentives:

• Immediate discount: "Scan to get 15% off today's order" (via the app).
• Loyalty points: "Earn 100 bonus points on your first app order."
• Exclusive access: "App-only menu items this week."
• Convenience: "Skip the wait, order from your table."

Landing Page vs Direct Store Link

A landing page between the QR code and the app store converts better than a direct store link:

Approach	Pros	Cons
Direct store link	One less step	No context, no fallback, no analytics
Landing page	Show value prop, capture emails, track conversions	Extra step before download

A landing page can also handle platform detection (iOS vs Android) and show the value proposition before sending users to the store.

Loyalty Program QR Codes

Enrollment

QR code on table tents: "Join rewards, earn free meals."

The deep link URL:

https://yourapp.com/loyalty/signup?source=table-tent&location=downtown

This opens the loyalty signup screen in the app. The source parameter lets you track which physical placement drives enrollments.

Check-In

Replace physical stamp cards with a QR code at the register:

The customer scans a QR code displayed at the POS. The QR code contains a rotating URL or token that the app validates:

https://yourapp.com/loyalty/checkin?token=abc123&location=downtown

The app confirms the check-in and credits the visit. Rotating tokens prevent screenshot-based fraud.

Analytics

Track QR code performance by using unique URLs per placement:

Placement	URL	Metric
Table tent (Downtown)	yourapp.com/menu?src=tt-downtown	Scans per day
Receipt	yourapp.com/reorder?src=receipt	Conversion to reorder
Takeout bag	yourapp.com/download?src=bag	App installs
Window sign	yourapp.com/order?src=window	Orders placed

This lets you compare which placements drive the most value and reallocate accordingly.

Design Tips

Contrast and Readability

• Use high-contrast QR codes. Black on white works best. Avoid placing QR codes on busy backgrounds or over photographs.
• Leave a quiet zone (white space) around the QR code, at least 4 modules wide.
• Add your logo to the center of the QR code only if you increase the error correction level to H (30% error tolerance).

Call to Action

Never print a QR code without context. "Scan me" is weak. Better examples:

• "Scan to order from your table"
• "Scan for 15% off your first app order"
• "Scan to join rewards"

Environmental Considerations

• Outdoor signage: Use larger QR codes (at least 10 cm for 1-meter scan distance) and weather-resistant materials.
• Dim lighting: Increase QR code size and contrast. Test scanning in the actual lighting conditions.
• Greasy environments: Laminated or acrylic surfaces resist kitchen/food contamination.

Tolinku for Restaurant QR Codes

Tolinku generates QR codes for any route. Each QR code links to a Tolinku route that handles platform detection, deep linking, and analytics. You can track scans, conversions, and app installs per QR code placement.
