QR Codes on Windows

A QR code on a window is a scannable, 2D barcode decal placed on a physical glass surface, such as a storefront, office, or vehicle window. Its primary benefit is to make a static, physical display interactive from the outside, allowing a user to scan with their smartphone to instantly access a website, view a menu, book an appointment, download an app, or get contact info, 24/7.

The Benefits of Using QR Codes on Windows

A QR code makes your window a “silent salesperson,” engaging customers even when you’re not there.

1. Capture Leads 24/7, Even When You’re Closed

Your business is closed, but a potential customer is walking by at 10 PM. A traditional window is a dead end. A QR code is an open door.

• A Dynamic Link QR Code can take them to your e-commerce store to make a purchase right from the sidewalk.
• A Dynamic Link on a salon or spa window can link to a “Book an Appointment” page.
• A Dynamic vCard QR Code on an office window lets a potential B2B client save your firm’s contact details instantly.

2. Provide Instant, Frictionless Information

A customer is in a hurry and doesn’t want to come inside just to ask a question. A QR code gives them the answer they need, instantly.

• A Dynamic Link QR Code on a restaurant window can link to the full menu, letting passersby browse before committing.
• A Dynamic Link on a “For Rent” or “For Sale” sign in a window can link to a full photo gallery, video tour, and agent contact info.
• A Phone QR Code can be used for a “Scan to Call” action for immediate inquiries.

3. Showcase Your Full Menu or Catalog

Your window display can only show a few items. A QR code is a portal to your entire inventory. A retail store can use a Dynamic Link QR Code on a mannequin display to link to the “Shop This Look” page, showing all available colors and related accessories. This turns your window display into an interactive catalog.

4. Measure Your Foot Traffic and Interest

This is the most powerful benefit of using Dynamic QR Codes. For the first time, you can get real data on your window’s effectiveness. How many people who walk by are actually interested in your products? Your analytics dashboard can show you:

• Total Scans: How many people scanned your “After-Hours Shopping” code?
• Time of Day: Are you getting more scans at 8 PM or on Sunday afternoon?
• Location: If you have a chain of stores, you can see which location’s window display is performing best. You can A/B test different window posters (e.g., “20% Off” vs. “New Collection”) to see which one drives more scans.

How to create a QR Code on a Window?

1. Log in or Sign up for your free TLinky account.
2. Dashboard → Click “QR Codes” → Select “Create QR”
3. Type QR Code Name & Select Static or Dynamic QR code.
4. Select your QR Code Type – For windows, we recommend a Dynamic Link (for menus/e-commerce) or a Dynamic vCard (for office contact). A Static WiFi code is also great for cafes.
5. Customize color, fonts & shape, etc., to match your brand.
6. Generate QR & Download (PNG, WEBP, SVG, PDF).

*Pro tip: Use Dynamic QR Codes to edit or replace all the information at any time without reprinting a new QR Code. This is essential for a semi-permanent decal. If your menu changes or your promotion ends, your window decal is never outdated. Just personalize.

QR Codes on Windows Best Practices

A window QR code must be scannable from a distance, through glass, and in various lighting conditions.

1. Add instructions

This is the most important rule. A code on a window needs a large, clear call to action (CTA).

• “SCAN TO SEE OUR MENU”
• “SCAN TO SHOP THE WINDOW”
• “WE’RE CLOSED? SCAN TO BOOK”
• “SCAN TO JOIN OUR WI-FI”

2. Frame it

On a glass window, a high-contrast frame is essential. It helps a phone’s camera lock onto the code, especially in bright sunlight or at night.

3. Add a logo inside your QR Code

This is a must for trust. A code with your company or restaurant logo in the center looks professional and assures users it’s safe to scan.

4. Save your designs

A professional platform allows you to save your branded designs as templates. This is perfect for a retail chain that needs to create consistent, on-brand QR codes for all its storefronts.

5. Customizable URL

On a pro plan, dynamic QR codes can use a custom short URL (e.g., yourbrand.com/window). This branded link is visible in some scanners and builds more trust.

6. Test before printing

This is the most critical step for window decals.

• Size: A 1-inch code is useless. A window code must be large and scannable from the sidewalk. We recommend a 1:10 size ratio (1 inch wide for every 10 inches of scan distance). For a 5-foot (60-inch) scan distance, your code should be at least 6 inches wide.
• Test for Glare: Print a test and stick it on the window. Does it scan at noon? At night? A matte finish decal is far better than glossy, as it reduces glare.
• Test for Tint: Does your window have a dark tint? This can block scanners. Test it.
• Inside or Outside? A decal on the outside is easier to scan. A decal on the inside (to be scanned from outside) is safer from weather and vandalism, but you must print it in reverse (mirrored).

• Restaurants & Cafes: Use a Dynamic Link QR Code on the front window for “Scan for Our Full Menu.” This lets customers browse before entering. They can also use a Static WiFi QR Code sticker for guests inside.

• Retail Stores: Use a Dynamic Link on a window display. A scan takes the shopper to that exact product’s e-commerce page. This is perfect for after-hours “window shopping.”
• Real Estate Offices: Use Dynamic Link QR Codes on window posters for each property. A scan links to the full listing, photo gallery, and video tour. This generates leads 24/7.
• Salons & Spas: Use a Dynamic Link on the front door to link to their “Book an Appointment” page, letting clients book a time even when the salon is closed.
• Vehicle Fleets: Use a Dynamic Link on the back window of a car or van. This is a key part of a QR Codes on Vehicles strategy, turning a traffic jam into a lead-generation opportunity.
